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.…

Out-of-time correlation functions in single-body systems
Andrew C. Hunt
In the study of quantum chaos, `out of time ordered correlators' (OTOCs) are commonly used to quantify the rate at which quantum information is scrambled. This rate has been conjec…
