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…

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…

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…
