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…
On the origin of exponential operator growth in Hilbert space
Vijay Ganesh Sadhasivam, Jan M. Rost, Stuart C. Althorpe
The question of thermalization in quantum many-body systems has long been studied through the properties of matrix elements of operators corresponding to local observables. More re…
Instantons and the quantum bound to chaos
Vijay Ganesh Sadhasivam, Lars Meuser, David R. Reichman +1
We investigate why the Lyapunov exponents of out-of-time-ordered correlators (OTOCs) satisfy a universal bound by probing imaginary-time path-integral spa…
