Libor Veis (J. Heyrovský Institute of Physical Chemistry, Academy of Sciences of the Czech Republic, v.v.i., Dolejškova 3, 18223 Prague 8, Czech Republic)

In the first part of the talk, I will review basic concepts of quantum chemical density matrix renormalization group (QC-DMRG), the method of choice for calculations of strongly correlated molecular systems, which is especially suitable for treatment of one-dimensional and quasi one-dimensional problems. I will also present our recent developments on local orbital optimization matching the two-site DMRG scheme [1] and introduce MOLMPS, the massively parallel QC-DMRG implementation which is currently under development [2].

In the second part, I will introduce the recently developed...

Abstract: Engineering novel materials with specific electronic, magnetic, optical or transport properties is a challenge for material science. It relies crucially on our understanding of the underlying physical mechanisms. Increasing our knowledge about electronic and magnetic properties of materials has thus immediate impact onto possible technological advances. The DFT+DMFT approach, which is a combination of the Dynamical Mean Field Theory and the Density Functional Theory is a powerful tool to study from first principles the magnetic and electronic properties of strongly...

Jiří Kaštil

In recent years, the search for new materials suitable for preparation of rare-earth-free permanent magnets has led to a renewed interest in the magnetic properties of Fe compounds with an anisotropic crystal structure, which may promise sizeable magnetic anisotropy and high Curie temperature. The Fe5SiB2 phase was discovered in 1960 by B. Aronsson and I. Engström. It possess a high Curie temperature of 845 K and a high value of saturated magnetization of about 9 μB / f.u.. The compound crystallizes in the tetragonal crystal structure of Cr5...

Dvořákova přednáška / Pátek, 21.06.2019 14:00 - 16:00

prof. Ramamoorthy Ramesh (Department of Physics and Department of Materials Science and Engineering, University of California, Berkeley, USA)

The 11th Dvořák Lecture

The emergence of the “Internet of Things” and the explosion of Artificial Intelligence/Machine Learning applications are likely to push up significantly the market for microelectronics. The related energy consumption could increase by 20–25%. Thus, looking for a new generation of ultralow power memories and switches is an area of significant current research. Perovskite oxides exhibit a rich spectrum of functional responses, including magnetism, ferroelectricity, highly correlated electron behavior, superconductivity, etc. Over the past...
