High-energy photon hologram of a photon gas
P. O. Kazinski, A. A. Sokolov
The photon hologram of a one-particle density matrix of a photon gas is derived including the case where the energy of a probe photon is above the electron-positron pair creation t…
-term Multi-Field Inflation in Supergravity without Stabiliser Superfields
Jinn-Ouk Gong, Sergei V. Ketov, Takahiro Terada
Realising -term slow-roll inflation in supergravity is non-trivial due to the well-known -problem. The common strategy to solve the problem is to impose a shift symmetry on t…
Towards Lagrangian dynamics for constrained mixed-symmetric interacting higher-spin fields
A. Reshetnyak
The necessary and sufficient conditions to construct consistent Lagrangian formulation for irreducible interacting massless higher-spin (HS) fields on -dimensional Minkowski spa…
Starobinsky inflation and Swampland conjectures
Sergei V. Ketov
This paper is devoted to memory of late Professor V. G. Bagrov, who was my first teacher in theoretical physics. About 45 years later, theoretical physics has changed and me too. T…
Einstein-Grisaru-Zanon gravity
Ruben Campos Delgado, Sergei V. Ketov
The leading -correction to the gravitational low-energy effective action of closed (type II) superstring theory in four-spacetime dimensions defines the Einstein-Grisaru-Za…
Vacuum instability in QED with an asymmetric x-step. New example of exactly solvable case
A. I. Breev, S. P. Gavrilov, D. M. Gitman
We present a new exactly solvable case in strong-field QED with one-dimensional step potential (x-step). The corresponding x-step is given by an analytic asymmetric with respect to…
Dilaton-axion modular inflation in supergravity
Daniel Frolovsky, Sergei V. Ketov
Dilaton and axion are ubiquitous in extended supergravities and closed superstrings. We propose new models of modular inflation in four-dimensional supergravity coupled to th…
Covariant Lagrangian Cubic Interaction Vertices For Irreducible Higher Spin Fields in Minkowski Backgrounds
Alexander A. Reshetnyak
We review the application of BRST and BRST-BV approaches to construct the generic off-shell local Lorentz covariant cubic interaction vertices for irreducible massless and massive…
Non-commutative gauge symmetry from strong homotopy algebras
Vladislav Kupriyanov, Fernando Oliveira, Alexey Sharapov +1
We explicitly construct an L algebra that defines U gauge transformations on a space with an arbitrary non-commutative and even non-associative star product.…
Gauge Invariant Lagrangian Formulations for Mixed Symmetry Higher Spin Bosonic Fields in AdS Spaces
A. Reshetnyak, P. Moshin
We deduce a non-linear commutator higher-spin (HS) symmetry algebra which encodes unitary irreducible representations of the AdS group -- subject to a Young tableaux $Y(s_1,\ldots…
Dualisation of free fields
V. A. Abakumova, S. L. Lyakhovich
We consider the general free field theory such that system of equations of motion includes a subsystem with a special property. If the subsystem is considered by itself, it would b…
Consistent Lagrangians for irreducible interacting higher-spin fields with holonomic constraints
I. L. Buchbinder, A. A. Reshetnyak
We study the aspects of constructing the interactions for the higher spin fields in the framework of BRST approach. The main object of such an approach is BRST operator acting in t…

We develop the BRST-BV approach to construct the general off-shell Lorentz covariant cubic, quartic, -tic interaction vertices for irreducible higher spin fields on -dimensio…

The explicit compact expression for the susceptibility tensor of a single photon wave packet on the photon mass-shell is derived. It is assumed that the probe photon is hard, the t…

We study the formation of primordial black holes (PBH) in the Starobinsky supergravity coupled to the nilpotent superfield describing Volkov-Akulov goldstino. By using the no-scale…

Ioseph Buchbinder, Evgeny Ivanov, Nikita Zaigraev
As a continuation of our previous papers arXiv:2109.07639 and arXiv:2202.08196, we study the linearized structure of the manifestly supersymmetric theory of t…

I. L. Buchbinder, E. A. Ivanov, B. S. Merzlikin +1
We study the off-shell structure of the two-loop effective action in supersymmetric gauge theories formulated in harmonic superspace. The off-…
