From coupled Rabi models to the Potts model
Anatoliy I. Lotkov, Valerii K. Kozin, Denis V. Kurlov +2
We study -symmetric Rabi model that describes a three-level system coupled to two bosonic modes. We derive a mapping of the two-mode Rabi model onto a…
Cat states in one- and two-mode Rabi models
Anatoliy I. Lotkov, Denis V. Kurlov, Valerii K. Kozin +2
We investigate one- and two-mode variants of the -symmetric quantum Rabi model, which describe the interaction of a qutrit with one or two bosonic modes and are direc…
Quantum computation with hybrid parafermion-spin qubits
Denis V. Kurlov, Melina Luethi, Anatoliy I. Lotkov +3
We propose a universal set of single- and two-qubit quantum gates acting on a hybrid qubit formed by coupling a quantum dot spin qubit to a parafermion qubit with…
Adiabatic Transformations in Dissipative and Non-Hermitian Phase Transitions
Pavel Orlov, Georgy V. Shlyapnikov, Denis V. Kurlov
The quantum geometric tensor has established itself as a general framework for the analysis and detection of equilibrium phase transitions in isolated quantum systems. We propose a…
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…
