Generalized Einstein-Maxwell theory: Seeley-DeWitt coefficients and logarithmic corrections to the entropy of extremal and non-extremal black holes
Sudip Karan, Binata Panda
We present a consolidated manual of Euclidean gravity approaches for finding the logarithmic corrections to the entropy of the full Kerr-Newman family of black holes in both extrem…

Logarithmic corrections to black hole entropy in matter coupled Einstein-Maxwell supergravity
Sudip Karan, Binata Panda
We calculate the first three Seeley-DeWitt coefficients for fluctuation of the massless fields of an Einstein-Maxwell supergravity theory (EMSGT) distributed into d…

Logarithmic correction to the entropy of extremal black holes in Einstein-Maxwell supergravity
Gourav Banerjee, Sudip Karan, Binata Panda
We study one-loop covariant effective action of \say{non-minimally coupled} , Einstein-Maxwell supergravity theory by heat kernel tool. By fluctuating the fiel…
