Coherent states in quantum billiards constructed in the basis of the continued eigenfunctions
I. D. Burkov, S. S. Seidov
In the article a new approach to construction of generalized coherent states in quantum billiards is proposed. The coherent states are defined as the projections of a Gaussian wave…
Analytical solution of coupled self--consistency and linearised Usadel equations for the dirty superconductors at and with the proximity effect
S. S. Seidov, N. G. Pugach
In this manuscript we consider a superconducting film in the vicinity of the critical temperature and presence of the proximity effect. We analytically solve the corresponding line…
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…
Density of states in the heterostructure ferromagnetic insulator-superconductor-ferromagnetic insulator
D. V. Seleznev, S. S. Seidov, N. G. Pugach +3
We consider a spin valve composed of a superconducting film (S) between two ferromagnetic insulators (FI) on two sides. In the dirty limit the superconductor is described by Usadel…
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…
On the size of superconducting islands on the density-wave background in organic metals
Vladislav D. Kochev, Seidali S. Seidov, Pavel D. Grigoriev
Most high- superconductors are spatially inhomogeneous. Usually, this heterogeneity originates from the interplay of various types of electronic ordering. It affects various s…
First-order phase transition between superconductivity and charge/spin-density wave as the reason of their coexistence in organic metals
Seidali S. Seidov, Vladislav D. Kochev, Pavel D. Grigoriev
The interplay between superconductivity (SC) and spin/charge density wave (DW) in organic metals shows many similarities to high- superconductors. It also contains many puzzle…
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…
