Exact tunneling splittings from symmetrized path integrals
George Trenins, Lars Meuser, Hannah Bertschi +3
We develop a new simulation technique based on path-integral molecular dynamics for calculating ground-state tunneling splitting patterns from ratios of symmetrized partition funct…
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…
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…
