Energy spectrum and quantum phase transition of the coupled single spin and an infinitely coordinated Ising chain
S. S. Seidov, N. G. Pugach, A. S. Sidorenko
We consider a spin model, composed of a single spin, connected to an infinitely coordinated Ising chain. Theoretical models of this type arise in various fields of theoretical phys…
Wigner current in multidimensional quantum billiards
S. S. Seidov, D. G. Bezymiannykh
In the present paper we derive the Wigner current of the particle in a multidimensional billiard -- the compact region of space in which the particle moves freely. The calculation…
Dicke model semiclassical dynamics in superradiant dipolar phase in the 'bound luminosity' state
S. I. Mukhin, A. Mukherjee, S. S. Seidov
Analytic solution of semiclassical dynamics equations of the Dicke model in a superradiant state is presented. The time dependences of the amplitudes of superradiant bosonic conden…
Quantum Dicke battery supercharging in the "bound luminocity" state
S. S. Seidov, S. I. Mukhin
Quantum batteries, which are quantum systems to be used for storage and transformation of energy, are attracting research interest recently. A promising candidate for their investi…
High-fidelity transmon coupler activated CCZ gate on fluxonium qubits
Ilya A. Simakov, Grigoriy S. Mazhorin, Ilya N. Moskalenko +2
The Toffoli gate takes a special place in the quantum information theory. It opens up a path for efficient implementation of complex quantum algorithms. Despite tremendous progress…
Wigner function dynamics with boundaries expressed as convolution
S. S. Seidov
In the present paper a method of finding the dynamics of the Wigner function of a particle in an infinite quantum well is developed. Starting with the problem of a reflection from…
Quantum beats of a magnetic fluxon in a two-cell SQUID
I. N. Moskalenko, I. S. Besedin, S. S. Seidov +2
We report a detailed theoretical study of a coherent macroscopic quantum-mechanical phenomenon - quantum beats of a single magnetic fluxon trapped in a two-cell SQUID of high kinet…
