New-born strings are tensionless
Sudip Karan, Bibhas Ranjan Majhi
We report a physical origin of tensionless strings, obtained by formulating string dynamics in finite-lifetime settings for the first time. Departing from the conventional paradigm…
A time-like window into tensionless worldsheets
Sudip Karan, Bibhas Ranjan Majhi
Rindler worldsheets are well known to transition into a tensionless regime in the infinite acceleration limit, acquiring an emergent Carrollian structure. In this work, we uncover…
Logarithmic correction to the entropy of a Kerr-Newman family of black holes in -charged STU supergravity models
Sudip Karan, Gurmeet Singh Punia, Surajit Biswas
The leading quantum-gravitational correction to the black hole entropy is known to be a universal logarithmic term. In this study, we investigate the logarithmic corrections for th…
Logarithmic correction to black hole entropy in universal low-energy string theory models
Sudip Karan, Gurmeet Singh Punia
We calculate the logarithmic correction to the entropy of asymptotically flat and AdS black holes (rotating, non-rotating, charged, and uncharged) embedded in Einstein-Maxwell-dila…
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…
