The numerical solution of a system of non-linear kinetic equations for electron distribution functions and non-equilibrium phonons is obtained for quantum cascade intersubband lasers on quantum wells and wires. In the case of quantum wells the analytical solution of system of equations is found....

We present a quantum-statistical theory using the Kubo formalism to describe both CIP (current in plane) and CPP (current perpendicular to the plane) giant magnetoresistance (GMR) of thin magnetic sandwiches. It is shown that GMR for both geometries oscillates with the thicknesses of the...

A distribution law of classical particle-diffusion toward that of the Gaussian process is extensively studied for molten AgI and Lennard–Jones liquid (liquid Ar) by molecular dynamics simulation. In a time scale of the order from 1ps to 100ps, a generalized spatio-temporal distribution law of...

Monte Carlo (MC) simulations, finite-size scaling and theoretical analysis have been carried out to study the critical behavior of long linear particles of length k (k-mers) on honeycomb lattices. A nematic phase, characterized by a big domain of parallel k-mers, is separated from the isotropic...

In this short note we collect together known results on the use of random matrix theory (RMT) in lattice statistical mechanics. The purpose here is two fold. Firstly the RMT analysis provides an intrinsic characterization of integrability, and secondly it appears to be an effective tool to find...
