Abstract: A bstractWe compute the topologically twisted index for general N=2$$ \mathcal{N}=2 $$ supersymmetric field theories on ℍ2×S1$$ {\mathrm{\mathbb{H}}}_2\times {S}^1 $$. We also discuss asymptotically AdS4 magnetically charged black holes with hyperbolic horizon, in four-dimensional N=2$$… read more here.

Abstract: Abstract We calculate the entropy of an asymptotically Schwarzschild black hole, using an effective field theory of winding modes in type II string theory. In Euclidean signature, the geometry of the black hole contains a… read more here.

DOI: 10.1103/physrevd.101.084028
Abstract: The main part of this work is to present a formula allowing a microscopic derivation of the Schwarzschild black hole entropy in arbitrary dimension. More generally, this Cardy-like formula applies for static black holes whose… read more here.

DOI: 10.1103/physrevd.96.026018
Abstract: We investigate the structure of the three-qubit magic Veldkamp line (MVL). This mathematical notion has recently shown up as a tool for understanding the structures of the set of Mermin pentagrams, objects that are used… read more here.

DOI: 10.3390/e22101110
Abstract: In a recent paper (Entropy 2020, 22(1), 17), Tsallis states that entropy—as in Shannon or Kullback–Leiber’s definitions—is inadequate to interpret black hole entropy and suggests that a new non-additive functional should take the role of… read more here.
