Tidal Love numbers of wormholes as black-hole mimickers
Sergey N. Solodukhin, Vagif Tagiev
We study the dynamical scalar tidal Love numbers of wormholes that provide viable mimickers for black holes, focusing on thin-shell Schwarzschild and Damour-Solodukhin geometries.…
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…
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)…
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…
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…
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…
