Pre-failure response spectra predict finite-amplitude fragility
Surachate Limkumnerd
Failure theories often identify a single leading route to failure: the most unstable mode, weakest link, minimum-action escape path, or optimal perturbation. Yet finite-amplitude s…
Path-Extrema Upper Bounds on Mean Entropy Production
Surachate Limkumnerd
Fluctuation relations imply the second-law inequality , but path extrema can also constrain how large the mean entropy production can be. For steady-state p…
Matrix-noise Jacobians in stochastic-calculus inference and optimal paths
Surachate Limkumnerd
Multiplicative noise makes stochastic dynamics depend on how the white-noise limit is interpreted. In multidimensional systems with matrix-valued noise amplitudes , this dep…
Weighted Phase-Space Paths for Exact Wigner Dynamics
Surachate Limkumnerd, Panat Phanthaphanitkul
A quantum state can be written in phase space, but the resulting object is not generally the probability density of a positive stochastic process on ordinary phase space. We spell…
