Three perspectives on entropy dynamics in a non-Hermitian two-state system
Alexander Felski, Alireza Beygi, Christos Karapoulitidis +1
A comparative study of entropy dynamics as an indicator of physical behavior in an open two-state system with balanced gain and loss is presented. We distinguish the perspective ta…
Dyson-Schwinger equations in zero dimensions and polynomial approximations
Carl M. Bender, Christos Karapoulitidis, S. P. Klevansky
The Dyson-Schwinger (DS) equations for a quantum field theory in -dimensional space-time are an infinite sequence of coupled integro-differential equations that are satisfied ex…
Underdetermined Dyson-Schwinger equations
Carl M. Bender, Christos Karapoulitidis, S. P. Klevansky
This paper examines the effectiveness of the Dyson-Schwinger (DS) equations as a calculational tool in quantum field theory. The DS equations are an infinite sequence of coupled eq…
