Equilibrating continuous-variable open quantum systems using stochastic classical trajectories in path-integral space
William H. D. Moore, Stuart C. Althorpe
Beyond the weak-coupling limit, open quantum systems equilibrate to a highly entangled thermal state. For continuous-variable systems, this state can be written explicitly as an im…
Exploiting the path-integral radius of gyration in open quantum dynamics
Andrew C. Hunt, Stuart C. Althorpe
A major challenge in open quantum dynamics is the inclusion of Matsubara-decay terms in the memory kernel, which arise from the quantum-Boltzmann delocalisation of the bath modes.…
Effective classical potential for quantum statistical averages
Vijay Ganesh Sadhasivam, Stuart C. Althorpe, Venkat Kapil
We present an effective potential that allows quantum thermal expectation values of a position-dependent observable to be estimated as a classical ensemble average of the correspon…
