The Beauty of Coherent Quantum States
Our group also participates in COST Action Nanoscale Coherent Hybrid Devices for Superconducting Quantum Technologies, supported by the European Cooperation in Science and Technology (COST). For more information see a recent video on YouTube.
Photon emission micromaser
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
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
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
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
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.
Crime at our Department
Doc. Jan Klíma, a long year member of our group, just published his new book of novellas Třikrát zločin (three times crime) with plot set also in the building of our department.
"Exceptionally good" grant GAUK
Student grant GAUK on Relativistic theory of spin-dependent transport in spintronic materials solved by David Wagenknecht, Libor Šmejkal, and Jakub Šebesta was evaluated as exceptionally good. Congratulation!
Quantum Mechanics II
The second book of Quantum Mechanics by J. Klíma and B. Velický just appeared in the bookstores.
