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…

Ponderomotive barriers in rotating mirror devices using static fields
Tal Rubin, Nathaniel J. Fisch
Particularly for aneutronic fusion schemes, it is advantageous to manipulate the fuel species differently from one another, as well as expel ash promptly. The ponderomotive effect…
