Entropic hypocoercivity via the Polchinski flow: an application to the lattice sine-Gordon model
Bowen Li, Jianfeng Lu
We develop a multiscale criterion for exponential decay of relative entropy in the canonical stochastic quantization of lattice field theories, the underdamped Langevin dynamics of…
Space-Time Log-Sobolev Inequality and Hypocoercive Hypercontractivity for Underdamped Langevin Dynamics
Bowen Li, Jianfeng Lu
We study hypercontractivity for underdamped Langevin dynamics with a convex confining potential whose spatial Gibbs marginal satisfies a logarithmic Sobolev inequality (LSI). Unlik…
Sharp hypocoercive convergence estimates for underdamped Langevin dynamics via the modified method
Zexi Fan, Bowen Li, Jianfeng Lu
In this note, we consider the underdamped Langevin dynamics with invariant measure . Assume that th…
Thermal expectation estimation via single-trajectory Gibbs sampling with non-destructive measurements
Hongrui Chen, Jiaqing Jiang, Bowen Li +1
Estimating thermal expectation values of quantum many-body systems is a central challenge in physics, chemistry, and materials science. Standard quantum Gibbs sampling protocols ad…
