Large D charged black hole as a Jackiw-Teitelboim gravity weakly coupled to the thermal graviton background
Oleg O. Novikov, Andrey A. Shavrin
The s-wave approximation to the black hole dynamics has attracted considerable attention recently. However, the near-AdS2 geometry of the near-horizon region and decoupling of the…
Holographic model for the first order phase transition in the composite Higgs boson scenario
Oleg O. Novikov, Andrey A. Shavrin
The composite Higgs model assumes that the Higgs field arises as the pseudo-Goldstone mode corresponding to a dynamical symmetry breaking in a new strongly coupled sector. We prese…
States localized on a boundary of the time-dependent parity-breaking medium
Oleg O. Novikov, Anna Zakharova
We consider the massive vector field propagating in the inhomogeneous parity-breaking medium, such as the dense hot hadronic matter with chiral imbalance. The transition between th…
The Franke-Gorini-Kossakowski-Lindblad-Sudarshan (FGKLS) Equation for Two-Dimensional Systems
Alexander A. Andrianov, Mikhail V. Ioffe, Ekaterina A. Izotova +1
Open quantum systems are, in general, described by a density matrix that is evolving under transformations belonging to a dynamical semigroup. They can obey the Franke-Gorini-Kossa…
Quantum decoherence of the homogeneous modes during inflation
Oleg O. Novikov, Arina M. Shtennikova
In this short note we consider the decoherence of the minisuperspace background degrees of freedom due to the long wavelength scalar and tensor perturbations becoming unobservable…
A Perturbation Algorithm for the Pointers of Franke-Gorini-Kossakowski-Lindblad-Sudarshan Equation
A. A. Andrianov, M. V. Ioffe, E. A. Izotova +1
This paper is devoted to the study of behavior of open quantum systems consistently based on the Franke-Gorini-Kossakowski-Lindblad-Sudarshan (FGKLS) equation which covers evolutio…
-symmetric quantum field theory on the noncommutative spacetime
Oleg O. Novikov
We consider the -symmetric quantum field theory on the noncommutative spacetime with angular twist and construct its pseudo-Hermitian interpretation. We explore the d…
Scattering in pseudo-Hermitian quantum field theory and causality violation
Oleg O. Novikov
The non-Hermitian but -symmetric quantum field theories are known to have a pseudo-Hermitian interpretation. However the corresponding intertwining operator happens t…
Integrable Minisuperspace Models with Liouville Field: Energy Density Self-Adjointness and Semiclassical Wave Packets
Alexander A. Andrianov, Chen Lan, Oleg O. Novikov +1
The homogeneous cosmological models with a Liouville scalar field are investigated in classical and quantum context of Wheeler-DeWitt geometrodynamics. In the quantum case of quint…
Inhomogeneous modes in the PT-symmetric quantum cosmology
O. O. Novikov
We consider the possibility to solve the issues of the phantom field cosmology by means of the PT-symmetric quantum theory. The Born-Oppenheimer approximation is applied to the Whe…
Quantum cosmology of the multi-field scalar matter: some exact solutions
Alexander A. Andrianov, Oleg O. Novikov, Chen Lan
We consider the gravity interacting with matter scalar fields and quantized in the minisuperspace approach in which the wave functional is described by the Wheeler-DeWitt equations…
Gravity effects on thick brane formation from scalar field dynamics
Alexander A. Andrianov, Vladimir A. Andrianov, Oleg O. Novikov
The formation of a thick brane in five-dimen\-sional space-time is investigated when warp geometries of type are induced by scalar matter dynamics and triggered by a thin-b…
CP violation in the models of fermion localization on a domain wall (brane)
Alexander A. Andrianov, Vladimir A. Andrianov, Oleg O. Novikov
A brief survey of fermion localization mechanism on a domain wall ("thick brane") generated by a topologically nontrivial vacuum configuration of scalar fields is given. The extens…
Localization of scalar fields on self-gravitating thick branes
Alexander A. Andrianov, Vladimir A. Andrianov, Oleg O. Novikov
The model of a domain wall ("thick" brane) in noncompact five-dimensional space-time is considered with geometries of type generated by self-interacting scalar matter. The…
