Derivation of the Redfield relaxation equation
so that we can write ∂ρI(t) ∂t = −2πi [Hr,I(t), ρI(t)] (2.4) This is a rather essential step, since we will assume that ρI varies slowly in time. If there was no perturbation, we would not have any variation at all, so the perturbation is assumed to make slow changes in ρI(t). The time dependence in Hr,I(t) now comes from two sources: the fluctuating field and the operators Ak,I which have now ...
متن کاملSymmetric Tensor Approximation Hierarchies for the Completely Positive Cone
In this paper we construct two approximation hierarchies for the completely positive cone based on symmetric tensors. We show that one hierarchy corresponds to dual cones of a known polyhedral approximation hierarchy for the copositive cone, and the other hierarchy corresponds to dual cones of a known semidefinite approximation hierarchy for the copositive cone. As an application, we consider a...
متن کاملA simple and accurate approximation of the inverse Langevin function
The inverse Langevin function cannot be represented in an explicit form and requires an approximation by a series, a non-rational or a rational function as for example by a Padé approximation. In the current paper an analytical method based on the Padé technique and the multiple point interpolation is presented for the inverse Langevin function. Thus, a new simple and accurate approximation of ...
متن کاملQuantum-classical approximation beyond Redfield theory
A quantum-classical approximation, capable of describing the evolution of open quantum systems well beyond the applicability limits of Redfield theory is suggested. The theory is based on the short lifetime of the quantum correlations between the quantum and the classical subsystem, caused by energy dispersion ~per degree of freedom! of the canonical bath. The resulting quantum-classical approx...
