Logarithm of charge ratio in black hole entropy
Muktajyoti Saha, Ashoke Sen, P. Shanmugapriya
Logarithmic correction to BPS black hole entropy, computed from microscopic description, often contains terms involving large ratios of charges, besides the logarithmic terms invol…

Quantum evolution of de Sitter black holes near extremality
Arindam Bhattacharjee, Muktajyoti Saha
We study the evolution of charged, asymptotically de Sitter black holes close to the cold extremal branch of the phase space. We consider black hole sizes that are parametrically s…

Logarithmic corrections to entropy of 3D cosmological solutions from celestial dual
Arindam Bhattacharjee, Shruti Menon, Muktajyoti Saha
Recently a one-dimensional Schwarzian type theory was proposed as an effective dual theory of pure gravity in (2+1) dimensional asymptotically flat spacetimes \cite{Bhattacharjee:2…
