We study the bath dynamics in the dephasing model of a two-state quantum system (qubit) coupled to an environment of harmonic oscillators. This model was shown [Morozov et al., Phys. Rev. A, 2012 85, 022101] to admit the ...

Based on the effective Hubbard model we suggest a statistical description of reaction-diffusion processes for bimolecular chemical reactions of gas particles adsorbed on the metallic surface. The system of transport ...

Short–wavelength asymptotics of time correlation functions (TCF) of simple classical fluids is considered in the framework of short time expansion. The explicit expressions for zeroth time moments up to the 8-th order ...
