Antiferromagnetic Spintronics

added on 24 June 2020, 10:00

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

added on 22 May 2020, 22:00

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

added on 22 May 2020, 21:00

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.

Photon emission micromaser

added on 18 January 2020, 11:42

T. Chlouba and T. Novotný studied a micromaser model based on a solid-state setup with a double quantum dot. They analyzed the method of full counting statistics used for the prediction of the bistability and identified a likely cause behind its failure.

Conductivity of magnetic topological insulators

added on 18 January 2020, 11:40

An experimental evidence and theory of the influence of an anomalous temperature dependence of the phase coherence length on the conductivity of magnetic topological insulators has been recently published in Physical Review Letter.

Atomic scale Kondo lattices

added on 31 May 2019, 9:20

Richard Korytár conducted a research on formation of the finite size analogue of a heavy Fermi liquid. In their study they have shown a possibility of fabrication artificial materials with novel electronic and magnetic properties.

Anomalous Hall effect in NiMnSb

added on 31 May 2019, 9:10

David Wagenknecht et al. present their fully relativistic density-functional theory treatment of nonzero temperatures. They calculate contributions of phonons and disorder to the temperature-dependent resistivity, anomalous Hall conductivity, and spin-resolved conductivity in ferromagnetic half-Heusler NiMnSb.

Tunable Josephson Junctions

added on 11 May 2019, 13:00

A practical guide to quantum phase transitions in quantum-dot-based tunable Josephson junctions by A. Kadlecová, M. Žonda, V. Pokorný, and T. Novotný you can now find in Physical Review Applied. Their results enable fast and efficient, yet reliable characterization and design of such nanoscopic tunable Josephson-junction devices.
