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.
