Towards a Holographic dual of Carrollian BCFT
Pronoy Chakraborty, Ritankar Chatterjee, Priyadarshini Pandit
In this work we aim to lay the foundation of flat version of AdS/BCFT correspondence through Carrollian framework. We begin with discussing the recently discovered Boundary…
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…
Tensionless Strings in a Kalb-Ramond Background
Aritra Banerjee, Ritankar Chatterjee, Priyadarshini Pandit
We investigate tensionless (or null) bosonic string theory with a Kalb-Ramond background turned on. In analogy with the tensile case, we find that the Kalb-Ramond field has a non-t…
Tensionless Tales of Compactification
Aritra Banerjee, Ritankar Chatterjee, Priyadarshini Pandit
We study circle compactifications of tensionless bosonic string theory, both at the classical and the quantum level. The physical state condition for different representations of B…
Non-Lorentzian Kač-Moody Algebras
Arjun Bagchi, Ritankar Chatterjee, Rishabh Kaushik +2
We investigate two dimensional (2d) quantum field theories which exhibit Non- Lorentzian Kač-Moody (NLKM) algebras as their underlying symmetry. Our investigations encompass both 2…
BMS Field Theories with Symmetry
Arjun Bagchi, Ritankar Chatterjee, Rishabh Kaushik +3
We investigate quantum field theories in two dimensions (2d) with an underlying Bondi-van der Burgh-Metzner-Sachs (BMS) symmetry augmented by currents. These fiel…
A Rindler Road to Carrollian Worldsheets
Arjun Bagchi, Aritra Banerjee, Shankhadeep Chakrabortty +1
The tensionless limit of string theory has recently been formulated in terms of worldsheet Rindler physics. In this paper, by considering closed strings moving in background Rindle…
