Hilbert space geometry and quantum chaos
Rustem Sharipov, Anastasiia Tiutiakina, Alexander Gorsky +2
The quantum geometric tensor (QGT) characterizes the Hilbert space geometry of the eigenstates of a parameter-dependent Hamiltonian. In recent years, the QGT and related quantities…
New spectral-parameter dependent solutions of the Yang-Baxter equation
Alexander. S. Garkun, Suvendu K. Barik, Aleksey K. Fedorov +1
The Yang-Baxter Equation (YBE) plays a crucial role for studying integrable many-body quantum systems. Many known YBE solutions provide various examples ranging from quantum spin c…
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…
Quantum metric of non-Hermitian Su-Schrieffer-Heeger systems
Chao Chen Ye, W. L. Vleeshouwers, S. Heatley +2
Topological insulators have been studied intensively over the last decades. Earlier research focused on Hermitian Hamiltonians, but recently, peculiar and interesting properties we…
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…
