Exploring the landscape of black hole mimickers
Sergey N. Solodukhin, Vagif Tagiev
We identify a general class of spacetime metrics that mimic the properties of black holes without possessing a true event horizon. These metrics are constrained by the requirements…
Cosmological singularity, conformal anomaly and symmetric polynomials
Sergey N. Solodukhin
We consider a spacetime singularity at arising in a Kasner-type metric that solves the gravitational equations modified by quantum effects of a conformal field theory (CFT)…
Auxiliary-Field Formalism for Higher-Derivative Boundary CFTs
Gregorio Paci, Sergey N. Solodukhin
We study the conformal field theory defined by the fourth-order operator on four-dimensional manifolds with boundaries, reformulating it through an auxiliary field so that the dyna…
Manifestations of chiral anomaly in a graphene plate
Sergey N. Solodukhin
Inspired by the Dirac model model of graphene, we consider a -dimensional fermionic system in which fermions are described by four-component spinors. These fermions are prop…
Boundary conformal invariants and the conformal anomaly in five dimensions
Amin Faraji Astaneh, Sergey N. Solodukhin
In odd dimensions the integrated conformal anomaly is entirely due to the boundary terms \cite{Solodukhin:2015eca}. In this paper we present a detailed analysis of the anomaly in f…
Islands for black holes in a hybrid quantum state
Yohan Potaux, Debajyoti Sarkar, Sergey N. Solodukhin
Following our previous work on hybrid quantum states in the RST model, we study its most interesting solution representing a completely regular spacetime with the structure of caus…
