Time-dependent thermoelectric transport in nanosystems
Črt Lozej, Tomaž Rejec
Izvirni znanstveni članek
Oznake: thermal conductivity;thermal properties;thermoelectric effects;transport properties;quantum dots;
Recently the Luttinger field approach was proposed by Eich et al. in Phys. Rev. B 90, 115116 (2014). as a way to simulate switching on a temperature gradient across a nanoscale device initially in thermal equilibrium. The time-dependent particle and heat currents can then be calculated by propagatin ...

In this thesis the classical and quantum dynamics in billiard systems are considered. Extensive numerical studies of the classical transport properties in several examples of billiard families including the ergodic Bunimovich stadium and cut-circle billiards and the mixed-type Robnik and lemon billi ...

Quantum chaos in triangular billiards
Črt Lozej, Giulio Casati, Tomaž Prosen
Izvirni znanstveni članek
Oznake: kvantna fizika;teroje kaosa;quantum chaos;quantum physics;
We present an extensive numerical study of spectral statistics and eigenfunctions of quantized triangular billiards. We compute two million consecutive eigenvalues for six representative cases of triangular billiards, three with generic angles with irrational ratios with π, whose classical dynamics ...

Phenomenology of quantum eigenstates in mixed-type systems: Lemon billiards with complex phase space structure
Črt Lozej, Dragan Lukman, Marko Robnik
Izvirni znanstveni članek
Oznake: kvantna fizika;energija;
The boundary of the lemon billiards is defined by the intersection of two circles of equal unit radius with the distance 2B between their centers, as introduced by Heller and Tomsovic [E. J. Heller and S. Tomsovic, Phys. Today 46, 38 (1993)]. This paper is a continuation of our recent papers on a cl ...

Fluctuating number of energy levels in mixed-type lemon billiards
Črt Lozej, Dragan Lukman, Marko Robnik
Izvirni znanstveni članek
Oznake: nonlinear dynamics;quantum chaos;mixed-type systems;energy level statistics;lemon billiards;billiards;
: In this paper, the fluctuation properties of the number of energy levels (mode fluctuation) are studied in the mixed-type lemon billiards at high lying energies. The boundary of the lemon billiards is defined by the intersection of two circles of equal unit radius with the distance 2B between the ...
