H2020-WIDESPREAD-2014-1 (2015-2016): SlovakION - Slovak Centre of Excellence in Ion Beam and Plasma Technologies for Materials Engineering and Nanotechnology 

The Center of Excellence SlovakION aims to become Eastern Europe’s leading research centre for ion beam and plasma technologies in materials engineering and nanotechnology. Based on cutting-edge research and closely integrated in an international network of research facilities, SlovakION’s holistic approach to innovation transfer and its close interaction with the regional industry will contribute to the economic development of Slovakia. The main focus lies with the automotive and electronics industry as pointed out in Slovakia’s Research and Innovation Strategy for Smart Specialisation. The TEAMING project shall help to develop the new Centre of Excellence as an internationally acclaimed source of excellent research. In close cooperation with the Slovak government and relevant industrial partners, SlovakION will establish and develop an integrated system for technology transfer and applied research. As a long term vision, this Slovak transfer model should be extended on other areas of research and industrial fields. The SlovakION project draws its strength from three major sources: (i) STU is Slovakia’s leading technical university with a long tradition of excellent research and education, (ii) As of today, already €42M has been committed for creating a state-of the- art facility for ion and plasma technologies. These funds were provided by the European Structural Investment Fund (ESIF), the Slovak Republic Government and the STU, and (iii) HZDR Dresden will be the leading support for SlovakION building on more than a decade of close collaboration. HZDR will not only bring its own experiences in breeding excellent research and develop fruitful technology transfer, but could draw on the whole Dresden research cluster including a leading technical university, several thematically linked Fraunhofer sites as well as several public-private partnerships fostering technology transfer.


VEGA- 1/0223/19 (2019-2022) Computational design of novel functional materials

The project focuses on broadening the vistas of the technologically important materials with transition metals and lanthanides by predicting and targeted design of new as-yet unknown phases using theoretical approaches based on atomic-scale quantum-mechanical modelling, evolutionary algorithms and direct phonon method. The studied systems will encompass new electronic materials for spintronics, multiferroics and superconductors. This study will allow for designing of the most effective and technologically attractive structural forms of the newly predicted phases particularly tuned for the functionality in question in accessible pressure and temperature ranges.

APVV-18-0168  (2019-2023) Quest for novel inorganic compounds with nickel, palladium, copper and silver by DFT modelling and ion beam synthesis

The current project aims at a thorough theoretical and experimental study of all important stoichiometries, which are currently missing from the structure map of binary oxides and halides of Group 10 (Ni, Pd) and 11 (Cu, Ag) metals. Absence of these simple chemical stoichiometries is disturbing and calls for an explanation. What are the reasons for these white spots on the huge seas of chemical stability? Are these compounds truly unstable? Or, maybe, they could be stable but not enough attention was paid to them? Answers to these and related questions will be given within the project using state-of-the-art approaches for search of new materials that will rely on combination of computational modelling at the atomic level and experimental physicochemical techniques, reactive magnetron sputtering deposition and ion implantation. Our strategy meets the urgent need of the modern world for highly effective screening of the unknown potential of available natural resources and the most economic use of available research infrastructures.


APVV-18-0161 (2019-2023) Quantum Monte Carlo for strongly correlated electronic systems

In recent years, single-determinant fixed-node diffusion Monte Carlo (FNDMC) reached high-standard accuracy in a number of diverse systems (where mean-field methods like DFT do not suffice) ranging from weakly bound noncovalent complexes to strongly correlated systems like solid transition-metal oxides at high pressures. Thanks to its favourable CPU cost scaling, parallelism, and direct access to periodicity, FNDMC gains popularity as an unprecedented benchmark tool for large realistic complex many-electron systems. Recent results however suggest, that the expected accuracy is not always accessible, sometimes the results are overvalued, or they depend on the parameters that have been ignored to date. The reason being incomplete understanding of FN approximation (FNA) and its interplay with other possible biases. Our goal is identification and development of deep conceptual understanding of the key FNDMC error sources in strong interaction limit. We plan to uncover the currently unknown links between generic nodal (position-space) properties (e.g.,topology) of fermionic wave functions, and, their connection to the structure of many-determinant expansions and 1-particle reduced density matrix occupation numbers, as well as separation of electron correlation energy to dynamic and nondynamic (strong, multireference) component, which will enable fundamental understanding of FNA limits and decoupling of FN-bias from other bias sources of FNDMC. We also plan screening of FNDMC accuracy in strongly interacting model systems and unprecedented method developments that go beyond FN approximation. In addition to deep physical insights to the strong correlation effects in complex many-electron systems and limits of FNDMC methodology, the results of the project will enable rational usage and fine bias control of this method valuable for large systems.


ESA PECS (2019-2021) Preparation for ATHENA MISSION by establishing Slovak Research Team oriented to existing X-ray missions and AGN study 

The aim of the project is to create and train a new satellite data analysis team, targeting mainly XMM-Newton (ESA), Chandra (NASA) and Swift (NASA) missions aimed at accretion systems, to prepare the currently non-existent platform for the future X-ray mission Athena (ESA). The project aims to have two aspects: X-ray data processing and active galactic nuclei (AGN), the first mentioned having a very weak base in Slovakia, and no longer exists at all, and is one of the main objectives of the planned ATHENA mission. During the first phase, the team must be able to process raw data from XMM-Newton, Chandra and Swift missions to obtain energy spectra and light curves. In the second phase, team will initiate systematic research on AGN and publish its results in scientific journals.


Schéma Návraty (01.04.2018 - 01.04.2019): Predictive modelling of new finctional materials for technological applications

The project focuses on search for novel materials for innovative technologies by means of atomic-scale computational modelling. We will gain new insights into fictionalization of transition metals in form of new inorganic compounds and their attractive solid-state phases. The computational approach will be based on learning algorithms combined with quantum-mechanical Density Functional Theory methods. The project will be realized in two stages. In the first stage, new systems with transition metals will be mapped and their crystal structures characterized. In the second stage, we will shift our attention to physico-chemical properties with the aim to functionalize the new systems for applications in electronics and spintronics.

SK-SRB-2016-0002 (01.01.2017-31.12.2017) C-Au chemical bond in gold ion implanted polyethylene: DFT modeling and experiment

The stability of polyethylene chains with partly Au substituted hydrogen is already confirmed by our preliminary results (theoretical group at ATRI MTF STU). IR spectra of various gold substituted PE chains will be modeled using DFT trying to explain and interpret experimental IR results for gold implanted polyethylene samples prepared in INS Vinca, Serbia. The main chemical and physical properties of the polymers will be predicted by computational chemistry methods.


APVV-15-0105 (2016-2020): Noncovalent interactions in systems of increasing complexity

A common idea of this project is providing benchmark wavefunction data (mostly CCSD(T)) that would support DFT predictions of energetics and properties of gradually complex systems. Noncovalent interactions will be analysed, contributions many-body terms to the non additivity will be evaluated. As a prototype, beryllium clusters will be studied, binding energies per atom of Be_n up to the solid state will be of interest. The focus will be on interactions of biologically relevant amino acid clusters extracted from protein structures in the Protein Data Bank, their geometry and stability. Another class of molecules considered are metal-ligand complexes, including heavy metals. The main goal is to understand the bonding mechanism in context of their size, from small complexes to nanoclusters. Relativistic effects provide one of instruments for this analysis as well as for the analysis of iodine containing species relevant to coolant system of the nuclear reactor and in 12 complexes with antithyroid drugs. Many-body dispersion interactions will be treated using DFT in connection with layered materials and molecular crystals, their structure, elastic and thermal properties and adsorption. The alteration of properties of solute molecules in solvents, is another consequence of intermolecular interactions. This will be considered in relativistic calculations of NMR shielding constants. We combine wavefunction and DFT methods having in mind controlled accuracy. Large systems are treated using DFT, but selection of functionals is supported by extensive benchmarks on model systems. This will be achieved by further extension of efficiency of the wavefunction methods towards treating model systems closer to large molecules of interest. Important part of the project is the development of relativistic methods as well as improvement of methods for dispersion treatment within DFT. All methodological achievements will be implemented in computer programs MOLCAS, DIRAC and VASP.

In our project we will focus on particular problems namely: ab initio calculations of cationic in-crystal polarizabilities, cavity embedded molecules and NMR and hyperfine propeties of semiconductor quantum dots.


VEGA- 1/0219/16 (2016-2018): High energy heavy ion-beam annealing of ion implantation synthesized silicon carbide

SiC is a promising material for a wide range of applications from semiconductor industry to e.g. in fuel elements of next generation nuclear power plants' reactors. The most recent method for SiC synthesis is based on carbon implantation into silicon substrate followed by High Energy Heavy-Ion-Beam Annealing (HE HIBA) is currently under development. Advantages of HE HIBA annealing are significantly lower temperature requirements, possibility of localized synthesis and short time of treatment, among other things. Synthesized silicon carbide will be analyzed and characterized by Rutherford backscattering spectrometry (RBS), Resonant Nuclear Reaction Analysis (R-NRA), X-ray diffraction (XRD) and transmission electron microscopy (TEM). Particularly the new experimental facility at MTF STU Trnava equipped with a 500 kV ion implanter and 6 MV tandem accelerator will be utilized. Relation between the main parameters of synthesis processes and of the resulting SiC layers will be studied.


VEGA-1/0335/16 (2016-2018): Searching for physical sources of the fast stochastic oscillations in accreating systems

The goal of the project is the study of the fast stochastic oscillations generated by turbulent accretion in cosmic objects, where the main driving mechanism is the accretion through a disc. This stochastic flickering usually does not originate only from a single source, hence the light curve is a superposition of more signals. Individual components can be identified by detailed study of the periodogram. For analysis of such complicated periodograms data with high cadence on long time-base are required. Ideal instrument satisfying such demands is the Kepler spacecraft. Its one-minute cadence on time-base over hundreds of days is a unique opportunity for our study. Together with our flickering simulating model based on turbulent accretion process we want to identify individual parts of the complicated periodograms calculated from Kepler telescope data, to localize their source and bring a complex model of accretion in some types of cosmic objects.


VEGA-1/0465/15 (2015-2018): Design of Al-TM alloys for on-board hydrogen production

The main goal of the project is identification and design of new aluminum alloys for on-board hydrogen production. Theoretical part will focus on study of corrosion properties of aluminum alloys, the influence of alloying elements on electrochemical stability of alloy surface will be evaluated. By methods of quantum chemistry (periodic DFT) we will study the electrode potential shift in alloys relative to pure metal. We will evaluate segregation energies of alloying elements, adsorption energies on alloys surfaces with respect to doping element. The impact of surface coverage of doping element on corrosion properties will be investigated. Based on the results of simulations, binary and ternary aluminum alloys suitable for hydrogen production will be designed.


VEGA-1/0770/13 (2013-2015): Structure, propeties and processes at surfaces and interfaces of materials: computational modeling.

Joining is an important technological process. Frequently, there is defined an upper limit for the joining temperature due to, e.g. undesirable phase transition in the joined materials and the technological need for decreasing of the joining temperature arises. This goal can be achieved by the melting point depression – its reduction in nanostructured material in comparison to the bulk material. Nano-multilayer foils of brazing filler alloy and diffusion barrier layer (DBL) was shown to be working concept in joining. In the proposed project we address by atomic scale modeling methods structural and thermodynamical properties of the nano-multilayer systems potentially applicable in joining technology. We will apply DFT methods to model structure of the brazing alloy and DBL material interfaces and fit effective potentials for subsequent classical molecular dynamics modeling of large scale structure of interfaces and simulation of melting point depression. Benchmark interaction energies will also be provided.


VEGA 1/0511/13 (2013 – 2015): Study of turbulent accretion process in accreating binary systems through flickering activit

The main purpose of the project is the study of the turbulent flow in high Reynolds number (Re) regime, not accessible in today’s laboratories. Accretion systems are unique cosmic experiments to do so. The turbulence minimum dimension scales in the fluid are described by the Re. The largest scales of fluid motion are set by the overall geometry of the flow and are dissipating into smaller eddies up to the minimal dimension scale. From the basic fluid mechanics it is well known that higher Re numbers yield smaller minimal dimension scale. From Re about 10^6 the dissipation toward smaller scales of turbulent elements is so strong that the fluid becomes quasilaminar. The bigger eddies should dissipate and hence disappear. Today Re estimates from Earth goes toward a value of about 10^8. What is happening then? The typical Re in an accretion disk of cataclysmic variables is of about 10^12 and one of the possibility to explain flickering are turbulence in the disc. Can the flow tell something about the size of the turbulence? Why do we observe the flickering if the turbulence should "disappear" for Re ~ 10^6?
