Evaluation of the probability current in the stochastic path integral formalism
Valentin Wilhelm, Matthias Krüger, Matthias Fuchs +1
The probability current is a vital quantity in the Fokker-Planck description of stochastic processes. It characterizes non-equilibrium stationary states and appears in linear respo…

A self-consistent current response theory of jamming and vibrational modes in low-temperature amorphous solids
Florian Vogel, Philipp Baumgärtel, Matthias Fuchs
We study amorphous solids with strong elastic disorder and find an un-jamming instability that exists, inter alia, in an harmonic model built using Euclidean random matrices (ERM).…

Properties of stable ensembles of Euclidean random matrices
Philipp Baumgärtel, Florian Vogel, Matthias Fuchs
We study the spectrum of a system of coupled disordered harmonic oscillators in the thermodynamic limit. This Euclidean random matrix ensemble has been suggested as model for the l…
