Web12 de jan. de 2024 · An experimentally relevant modification of the QRM, the asymmetric (or biased) quantum Rabi model (AQRM) is no longer invariant under this operator, but shows nevertheless characteristic degeneracies of its spectrum for half-integer values of , the parameter governing the asymmetry. participating in can improve flexibilityWebThe open Dicke model The Dicke model of Eq 1 assumes that the cavity mode and the two-level systems are perfectly isolated from the external environment. In actual experiments, this assumption is not valid: the coupling to free modes of light can cause the loss of cavity photons and the decay of the two-level systems (i.e. dissipation channels). participating in team meetingsWebFIG. 1. Schematic diagram showing the stable points in the potential V (x) = εx + ηx2 + x4. The local minima of the potential are marked by triangles. The circles mark local maxima in the potential. Panel (a) shows the case of positive η, which gives a single local minimum. Here we have taken ε = 0.
