The Tensionless Lives of Null Strings
Arjun Bagchi, Aritra Banerjee, Ritankar Chatterjee +1
The tensionless limit probes the very high energy regime of string theory in contrast to the well studied point-particle limit which reduces to Einstein gravity. Tensionless string…

Strings near BTZ black holes: A Carrollian Chronicle
Aritra Banerjee, Arkachur Bhattacharya, Sharang Rajesh Iyer +2
The BTZ black hole provides a tractable (2+1)-dimensional example for investigating string dynamics in curved spacetime. However, a systematic and robust analysis of the solution s…

Non-relativistic Strings: Classical solutions and exactly solvable models
Aritra Banerjee, Adrita Chakraborty, Nibedita Padhi
We discuss classical closed string solutions in non-relativistic two-sphere target spaces. These classes of solutions closely relate to the GKP-type, spinning and pulsating strings…
