One generalization of the Dicke-type models
Denis V. Kurlov, Aleksey K. Fedorov, Alexandr Garkun +1
We discuss one family of possible generalizations of the Jaynes-Cummings and the Tavis-Cummings models using the technique of algebraic Bethe ansatz related to the Gaudin-type mode…
Conformal symmetry in quasi-free Markovian open quantum systems
Anatolii I. Lotkov, Denis V. Kurlov, Aleksey K. Fedorov +2
Conformal symmetry governs the behavior of closed systems near second-order phase transitions, and is expected to emerge in open systems going through dissipative phase transitions…
Adiabatic eigenstate deformations and weak integrability breaking of Heisenberg chain
Pavel Orlov, Anastasiia Tiutiakina, Rustem Sharipov +3
We consider the spin-1/2 XXX chain weakly perturbed away from integrability by an isotropic next-to-nearest neighbor exchange interaction. Recently, it was conjectured that this mo…
