Spin correlations in spin blockade
Rafael Sánchez, Sigmund Kohler, Gloria Platero
We investigate spin currents and spin-current correlations for double quantum dots in the spin blockade regime. By analysing the time evolution of the density matrix, we obtain the…
Quantum chaos and its kinetic stage of evolution
L. Chotorlishvili, A. Ugulava
Usually reason of irreversibility in open quantum-mechanical system is interaction with a thermal bath, consisting form infinite number of degrees of freedom. Irreversibility in th…
Surmounting collectively oscillating bottlenecks
D. Hennig, L. Schimansky-Geier, P. Hänggi
We study the collective escape dynamics of a chain of coupled, weakly damped nonlinear oscillators from a metastable state over a barrier when driven by a thermal heat bath in comb…
Formation of vortices in a dense Bose-Einstein condensate
V. P. Barros, Ch. Moseley, A. Gammal +1
A relaxation method is employed to study a rotating dense Bose-Einstein condensate beyond Thomas-Fermi approximation. We use a slave-boson model to describe the strongly interactin…
Exact results in a slave boson saddle point approach for a strongly correlated electron model
Raymond Fresard, Thilo Kopp
We revisit the Kotliar-Ruckenstein (KR) slave boson saddle point evaluation for a two-site correlated electron model. As the model can be solved analytically, it is possible to com…
Kekule-distortion-induced Exciton instability in graphene
Raoul Dillenschneider
Effects of a Kekule distortion on exciton instability in single-layer graphene are discussed. In the framework of quantum electrodynamics the mass of the electron generated dynamic…
