Quantum quenches in integrable systems: Constraints from factorisation
Dirk Schuricht
TL;DR
This paper investigates quantum quenches in integrable systems with strict factorisation, revealing that simultaneous particle transmission and creation cannot occur in generic interacting theories.
Contribution
It demonstrates that complete factorisation constraints prohibit simultaneous particle transmission and creation during quantum quenches in generic integrable models.
Findings
Simultaneous transmission and creation of particles are impossible under factorisation.
Factorisation constraints impose strict limitations on quench dynamics.
Results apply broadly to interacting integrable systems.
Abstract
We consider quantum quenches in integrable systems where complete factorisation of scattering, transmission and particle creation processes is assumed at all times. We show that under this assumption, the simultaneous transmission and creation of particles is impossible in generic interacting theories.
