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.
Ulrafast spin transfer torque
P. Baláž, M. Žonda, K. Carva et al. presented a theoretical model of generation of spin transfer torque in metallic spin valves using a femtosecond laser pulse.
I. Turek contributed to a research demonstrating reproducible switching in antiferromagnetic Mn2Au using current pulse generated bulk spin-orbit torques and read-out by magnetoresistance measurements.
R. Sýkora and T. Novotný commented on a paper discussing a question "Is the Antiresonance in Meta-Contacted Benzene Due to the Destructive Superposition of Waves Traveling Two Different Routes around the Benzene Ring?"
Ultrafast relaxation dynamics
P. Maldonado, K. Carva et al. presented a research on ultrafast relaxation dynamics in metals. They developed an out-of-equilibrium theory that captures the full dynamic evolution of the electronic and phononic populations and provides a microscopic description of the transfer of energy delivered optically into electrons to the lattice.
Handbook of Magnetic Materials
K. Carva, P. Baláž, and I. Radu contributed to the Handbook of Magnetic Materials (vol. 26) with a chapter entitled Laser-Induced Ultrafast Magnetic Phenomena.
