Long-time soliton dynamics via a coarse-grained space-time method
Dung N. Pham, Zoe Zager, Wentao Fan +1
We investigate the long-time dynamics of the Sine-Gordon (SG) model under a class of perturbations whose quantum field theoretic analog - via bosonization - corresponds to the mass…

Generalized Time-Coarse Graining via an Operator Cumulant Expansion
Leon Bello, Tal Rubin, Wentao Fan +2
We introduce a general framework for deriving effective dynamics from arbitrary time-dependent generators, based on a systematic operator cumulant expansion. Unlike traditional app…
