Composite scalar bosons masses: Effective potential versus Bethe-Salpeter approach
Physics Letters B, 2023 Ten years ago the 125 GeV Higgs resonance was discovered at the LHC [1,2], if this boson is a fundamental particle or a particle composed of new strongly interacting particles is still an open question.

Physics Letters B, 2022 We investigate the effect of peculiar velocities of inhomogeneities and the spatial curvature of the universe on the shape of the gravitating potential. To this end, we consider scalar perturbations of the FLRW metric.

Extend Bekenstein’s theorem to Einstein–Maxwell-scalar theories with a scalar potential
European Physical Journal C: Particles and Fields, 2022 The Bekenstein’s theorem allows us to generate an Einstein-conformal scalar solution from a single Einstein-ordinary scalar solution. In this article, we extend this theorem to the Einstein–Maxwell-scalar (EMS) theory with a non-minimal coupling between ...

DONKIN'S DIFFERENTIAL OPERATORS FOR HOMOGENEOUS HARMONIC FUNCTIONS
St. Petersburg Polytechnical University Journal: Physics and Mathematics, 2019 The work continues the study of Donkin operators for homogeneous harmonic functions. Previously, a basic list of such first-order operators for three-dimensional harmonic functions was obtained.

GENERALIZATION OF THE THOMSON FORMULA FOR HOMOGENEOUS HARMONIC FUNCTIONS
St. Petersburg Polytechnical University Journal: Physics and Mathematics, 2019 It is shown that the Thomson formula for three-dimensional harmonic homogeneous functions can be generalized if, instead of purely algebraic linear expressions, one uses a linear algebraic form with the participation of the first order partial ...

Global strain-induced scalar potential in graphene devices
Communications Physics, 2021 The electrical and optical properties of a material depend strongly on the details of its crystal structure. Here, the authors report a technique to mechanically deform the lattice of monolayer graphene with strain, and electrically detect the generation

BASIC DONKIN'S DIFFERENTIAL OPERATORS FOR HOMOGENEOUS HARMONIC FUNCTIONS
St. Petersburg Polytechnical University Journal: Physics and Mathematics, 2019 It is shown that there are the differential operators that transform three-dimensional homogeneous harmonic functions into new three-dimensional homogeneous harmonic functions.

Quantum corrections to slow-roll inflation: scalar and tensor modes
Journal of High Energy Physics, 2021 Inflation is often described through the dynamics of a scalar field, slow-rolling in a suitable potential. Ultimately, this inflaton must be identified with the expectation value of a quantum field, evolving in a quantum effective potential. The shape of

GENERALIZATION OF THE THOMSON FORMULA FOR HARMONIC FUNCTIONS OF A GENERAL TYPE
St. Petersburg Polytechnical University Journal: Physics and Mathematics, 2019 It is shown that the Thomson formula for three-dimensional harmonic functions is unique. Namely, there are no other formulas of this type, with the exception of the trivial change of variables in the form of shifts, reflections, rotations and stretching ...
