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…

Boundary Carroll CFTs: SUSY and Superstrings
Arjun Bagchi, Shankhadeep Chakrabortty, Pronoy Chakraborty +2
We consider two dimensional superconformal Carrollian theories with boundaries and construct two variants of the Boundary Superconformal Carrollian Algebra (BSCCA), viz. the Homoge…

Boundary Carrollian CFTs and Open Null Strings
Arjun Bagchi, Pronoy Chakraborty, Shankhadeep Chakrabortty +3
We consider Carrollian conformal field theories in two dimensions and construct the boundary Carrollian conformal algebra (BCCA), opening up innumerable possibilities for further s…
