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…

No-signaling principle and quantum brachistochrone problem in $P T$ -symmetric fermionic two- and four-dimensional models

Alireza Beygi, S. P. Klevansky

Fermionic systems differ from bosonic ones in several ways, in particular that the time-reversal operator $T$ is odd, $T^{2} = - 1$ . For $P T$ -symmetric bosonic systems, the no-signaling…

Coupled Oscillator Systems Having Partial PT Symmetry

Alireza Beygi, S. P. Klevansky, Carl M. Bender

This paper examines chains of $N$ coupled harmonic oscillators. In isolation, the $j$ th oscillator ( $1 \leq j \leq N$ ) has the natural frequency $ω_{j}$ and is described by the Hamilto…
