Reverse Transportation and Harnack Inequalities for Underdamped Langevin in the Non-convex Setting
Andreas Habring, Laurenz Nagler
We establish a dimension-free long-time reverse transportation, respectively Harnack inequality for the underdamped Langevin dynamics with non-convex potential. Specifically, we pr…

Annealed Underdamped Langevin Dynamics
Laurenz Nagler, Alexander Falk, Andreas Habring
In sampling, different flavours of annealing, tempering, or other successive approximation approaches are widely used and studied. In this work we investigate annealed underdamped…
