Log-Sobolev inequalities for boundary-driven anharmonic chains
Jianfeng Lu
The paper proves uniform logarithmic Sobolev inequalities for a weakly anharmonic chain of oscillators driven at its ends by Langevin thermostats at different temperatures, showing…

Structure-preserving numerical schemes for Lindblad equations
Yu Cao, Jianfeng Lu
We study a family of structure-preserving deterministic numerical schemes for Lindblad equations. This family of schemes has a simple form and can systemically achieve arbitrary hi…
