Ultrafast relaxation dynamics

added on 2 December 2017, 13:10

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

added on 2 December 2017, 13:00

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.

Molecules and the graph theory

added on 20 May 2017, 20:35

Ruda Sýkora and Tomáš Novotný present a method based on graph theory for the evaluation of the inelastic propensity rules for molecules exhibiting complete destructive quantum interference in their elastic transmission. The method can be fully automated and they provide a functional website running a code using Wolfram Mathematica which allows everyone to examine their molecules.

Superconducting quantum dot: symmetric vs. asymmetric

added on 18 May 2017, 16:50

A. Kadlecová and her mates studied the Anderson single-level quantum dot attached to two BCS superconducting leads. They revealed that a system with asymmetric tunnel coupling to the leads can be related to the symmetric one. Surprisingly, it is the symmetric case which is the most general, meaning that all physical quantities in the case of asymmetric coupling are fully determined by the symmetric ones.
