A twist on bilayers
Bilayer materials are receiving a lot of attention due to their two-dimensional nature and promising applications in, e.g., optoelectronics. A recent paper, co-authored by A. Slobodeniuk, presents optical properties of MoS2 with one layer turned against the other.
Unsupervised phase classification
Correct phase diagrams of strongly correlated systems, e.g., high temperature superconductors or spintronics materials, are important roadmaps for future applications. However, because of their complexity and the fact that we might not even know all of the phases of a particular system, their construction is a complicated and often cumbersome task. Yet, it does not have to be if we entrust it into the hands of a new machine learning method introduced in the recent PRResearch paper coauthored by Martin Žonda.
Alžběta’s recent PRL
Wonderful news! Our PhD student Alžběta Kadlecová is the only Czech coauthor on a recent article published in Physical Review Letters. In a collaboration with Université Paris-Saclay, a surprising decrease of the AC Josephson current in a carbon nanotube quantum dot is studied. Congratulations, Alžběta!
Jakub’s successful PhD defense
Jakub Šebesta defended his PhD thesis on March 15. Congratulations, Jakub, and best wishes for your new postdoc career! Jakub stayed in our group for a bit more than four years and published four articles, including a very recent paper in Physical Review B .
Our research on the APL cover
Recently our theory-experiment collaboration on the ultrafast spin manipulation using precisely tailored femtosecond laser pulses has been published in the Applied Physics Letters. It has been selected as a featured article at the cover of the latest APL issue.
Advances and challenges in single-molecule electron transport
A thorough review on measurement techniques and recent theories on electronic transport in single molecule magnets coauthored by R. Korytár just appeared in Reviews of Modern Physics.
Our ab initio calculations as well as collaboration with experiment have resulted in two recent publications on CuMnAs properties. In the first one, the finite temperature magnetism and resistivity of antiferromagnetic CuMnAs is described. The second one studies electrical transport properties of bulk tetragonal CuMnAs.
Dynamics due to femtosecond laser pulse
In a short period two of our papers on ultrafast magnetization dynamics due to femtosecond laser pulse has been accepted and published in Phys. Rev B. The first one studies laser-induced dynamics of a magnetic domain walls, while the second one focuses on THz spin waves generation due to superdiffusive spin transport.
Tracking ultrafast energy flow
A recent paper with contribution by K. Carva, suggested by Phys. Rev. B editor, studies ultrafast nonequilibrium energy flow between electronic and lattice degrees of freedom in crystalline nickel. By combining ab initio calculations with ultrafast diffuse electron scattering, the authors provide a detailed understanding of the complex nonequilibrium energy transfer between electrons and phonons in laser-excited Ni metal.
