Topological quantum pump of strongly interacting fermions in coupled chains

open access: yesNew Journal of Physics, 2019
We analyse a tight binding model of two coupled chains with strongly interacting fermions. Depending on the parameter w , the many body lowest energy band consists of either single particles or bound pairs.

Standard model alignment scenarios for Higgs bosons

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2016
This paper describes the model NMSSM with effective explicit and spontaneous CP-violations, and additional mixing of CP-even and CP-odd Higgs bosons states. The neutral Higgs bosons masses and decay widths were calculated at fixed parameters of the model

Supersymmetrical Separation of Variables in Two-Dimensional Quantum Mechanics

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2010
Two different approaches are formulated to analyze two-dimensional quantum models which are not amenable to standard separation of variables. Both methods are essentially based on supersymmetrical second order intertwining relations and shape invariance -

Resolutions of Identity for Some Non-Hermitian Hamiltonians. I. Exceptional Point in Continuous Spectrum

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2011
Resolutions of identity for certain non-Hermitian Hamiltonians constructed from biorthogonal sets of their eigen- and associated functions are given for the spectral problem defined on entire axis.

Resolutions of Identity for Some Non-Hermitian Hamiltonians. II. Proofs

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2011
This part is a continuation of the Part I where we built resolutions of identity for certain non-Hermitian Hamiltonians constructed of biorthogonal sets of their eigen- and associated functions for the spectral problem defined on entire axis.

The Cigar-Shaped Background Metric with Supersymmetry Approaches and Thermal Properties of System [PDF]

open access: yesIranian Journal of Astronomy and Astrophysics
In this paper, we introduce the cigar- shaped metric . Such metric can be obtained by the Schwarzschild black hole. Here, we write the Dirac equation in the corresponding background.
