Wavepackets in inhomogeneous periodic media: effective particle-field dynamics and Berry curvature
Alexander B. Watson, Jianfeng Lu, Michael I. Weinstein
We consider a model of an electron in a crystal moving under the influence of an external electric field: Schrödinger's equation with a potential which is the sum of a periodic fun…
A Mathematical Theory of Optimal Milestoning (with a Detour via Exact Milestoning)
Ling Lin, Jianfeng Lu, Eric Vanden-Eijnden
Milestoning is a computational procedure that reduces the dynamics of complex systems to memoryless jumps between intermediates, or milestones, and only retains some information ab…
Thermodynamic Limit of Crystal Defects with Finite Temperature Tight Binding
Huajie Chen, Jianfeng Lu, Christoph Ortner
We consider a tight binding model for localised crystalline defects with electrons in the canonical ensemble (finite electronic temperature) and nuclei positions relaxed according…
