Spacing statistics in two-mode random lasing
Oleg Zaitsev
The distribution of spacings between the lasing frequencies for an ensemble of random lasers in the two-mode regime was computed. The random lasers are implemented as open chaotic…
Mode statistics in random lasers
Oleg Zaitsev
Representing an ensemble of random lasers with an ensemble of random matrices, we compute average number of lasing modes and its fluctuations. The regimes of weak and strong coupli…
Semiclassical theory in Andreev billiards: beyond the diagonal approximation
Oleg Zaitsev
Recently semiclassical approximations have been successfully applied to study the effect of a superconducting lead on the density of states and conductance in ballistic billiards.…
Semiclassical theory of weak antilocalization and spin relaxation in ballistic quantum dots
Oleg Zaitsev, Diego Frustaglia, Klaus Richter
We develop a semiclassical theory for spin-dependent quantum transport in ballistic quantum dots. The theory is based on the semiclassical Landauer formula, that we generalize to i…
The role of orbital dynamics in spin relaxation and weak antilocalization in quantum dots
Oleg Zaitsev, Diego Frustaglia, Klaus Richter
We develop a semiclassical theory for spin-dependent quantum transport to describe weak (anti)localization in quantum dots with spin-orbit coupling. This allows us to distinguish d…
Localization by interference: Square billiard with a magnetic flux
R. Narevich, R. E. Prange, Oleg Zaitsev
Eigenstates and energy levels of a square quantum billiard in a magnetic field, or with an Aharonov-Bohm flux line, are found in quasiclassical approximation, that is, for high eno…
