Weakly interacting Bose gases below the critical temperature
E. Kovalchuk, R. Kobes
We consider a homogeneous non-ideal Bose gas at nonzero temperature in equilibrium below the critical temperature in the framework of finite temperature field theory. An algo…

A Relationship Between Parametric Resonance and Chaos
R. Kobes, S. Peles
In this paper we study two types of exponential instability -- parametric resonance and chaos. We show that a given equation may produce chaos or parametric resonance, depending ho…

Finite size effects in metallic superlattice systems
J. Chen, R. Kobes, J. Wang
Clean metallic superlattice systems composed of alternating layers of superconducting and normal materials are considered, particularly aspects of the proximity effect as it affect…
