Reply to "Comment on `Multiparty quantum mutual information: An alternative definition'"
Asutosh Kumar
We reaffirm the claim of Lee et al. [preceding Comment, Phys. Rev. A 108, 066401 (2023)] that the expression of quantum dual total correlation of a multipartite system in terms of…
Small Black String Thermodynamics
Jyotish Kumar, Sudhaker Upadhyay, Himanshu Kumar Sudhanshu
We consider a cylindrically symmetric solution for the field equations of Einstein-Hilbert action with a negative cosmological constant in four dimensions. The small statistical fl…
Charged Black Holes in Einstein--Gauss--Bonnet Massive Gravity
Prosenjit Paul, Sudhaker Upadhyay, Dharm Veer Singh
We investigate Einstein--Gauss--Bonnet--Maxwell massive gravity in AdS background and find an exact black hole solution. The horizon structure of the black holes studied. Trea…
Quasinormal Modes and Phase Structure of Regular Einstein-Gauss-Bonnet Black Holes
Yerlan Myrzakulov, Kairat Myrzakulov, Sudhaker Upadhyay +1
In this paper, we present an exact regular black hole solution in Einstein-Gauss-Bonnet coupled with nonlinear matter fields. It is a generalization of a regular Einstein-Gauss-Bon…
Weak Deflection Angle, Greybody Bound and Shadow for Charged Massive BTZ Black Hole
Sudhaker Upadhyay, Surajit Mandal, Yerlan Myrzakulov +1
We provide a discussion on a light ray in a charged black hole solution in massive gravity. To serve the purpose, we exploit the optical geometry of the black hole solution and fin…
