The spectrum of states of Ba~nados-Teitelboim-Zanelli black hole formed by a collapsing dust shell
Alexander A. Andrianov, Danila Lyozin, Artem Starodubtsev
We perform canonical analysis of an action in which 2+1-dimensional gravity with negative cosmological constant is coupled to cylindrically symmetric dust shell. The resulting phas…
Natural cancellation of powerlike divergences in the SM by dark matter through gauged Higgs portal
S. S. Afonin, A. A. Andrianov, V. A. Andrianov +1
We discuss the connection between the vacuum energy problem and the number of dark matter sectors and its relation to the cancellation of quadratic divergences both in the cosmolog…
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 Analysis of BTZ Black Hole Formation Due to the Collapse of a Dust Shell
Alexander A. Andrianov, Artem Starodubtsev, Yasser Elmahalawy
We perform Hamiltonian reduction of a model in which 2+1 dimensional gravity with negative cosmological constant is coupled to a cylindrically symmetric dust shell. The resulting a…
Vector mesons spectrum in a medium with a chiral imbalance induced by the vacuum of fermions
Vladimir Kovalenko, Alexander Andrianov, Vladimir Andrianov
The properties of the light vector mesons in the presence of local parity breaking medium with a chiral imbalance are considered in the vector-meson dominance model. Applying the f…
Emission of photons by quasiparticles in Weyl semimetals
Alexander Andrianov, Roberto Soldati, Dmitri Vassilevich
We show that quasiparticles in Weyl semimetals may decay with emission of a single photon. We study the spectrum of emitted photons and estimate the decay rates.
