... We use the word analogue rather than limit here because surface-hopping is not a rigorous classical limit. As a result, there are several variations of surface-hopping with di†erent hopping algorithms. The intent of surface-hopping is to improve on the Ehrenfest mean-Ðeld method in situations where ...

The identical systems in contact with the reservoir constitute the canonical ensemble. This approach works well for the high-tem ...

Order by disorder in a four-flavor Mott insulator on the fcc lattice
... A particularly simple choice of the parameter set {ϑz } corresponds to the helical states, defined by a ϑz varying linearly with the position of the plane along the z axis, ϑz = z ϑ in Eq. (12). The classical field of the helical state can be expressed in the following recursive form: ξ r+δ = R(−ϑ/2 ...

In consequence, the distance D[ρ1 ,ρ2 ] between two states can tend to zero when the system approaches a unique steady state (i.e., the dynamics is relaxing). We emphasize that contractivity is not a universal feature but depends on the metric: Quantum evolu ...
