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…
Chemical Reaction Dynamics under Vibrational Strong Coupling
Andrew C. Hunt
In this thesis, we use classical, semi-classical and quantum-mechanical methods to simulate chemical reaction dynamics inside of an optical cavity. Within such a cavity, by selecti…
Thermal quenching of classical and semiclassical scrambling
Vijay Ganesh Sadhasivam, Andrew C. Hunt, Lars Meuser +2
Quantum scrambling often gives rise to short-time exponential growth in out-of-time-ordered correlators (OTOCs). The scrambling rate over an isolated saddle point at finite tempera…
