Spectral gap estimates for Brownian motion on domains with sticky-reflecting boundary diffusion
Vitalii Konarovskyi, Victor Marx, Max von Renesse
Introducing an interpolation method we derive lower bounds for the spectral gap for Brownian motion on general domains with sticky-reflecting boundary diffusion associated to the f…

Adiabatic Approximation of Coarse Grained Second Order Response
Fenna Müller, Max von Renesse
We propose estimators for dynamic second order response theory in coarse grained variables for driven out-of-equilibrium subsystems. The error is controlled through the the notion…
