Carrollian ABJM: Fermions and Supersymmetry
Arjun Bagchi, Arthur Lipstein, Saikat Mondal +1
A natural approach for constructing a concrete example of flat space holography is to take the flat space limit of a well-understood example of AdS/CFT, such as the one relating M-…
High energy scattering and null strings
Arjun Bagchi, Sachin Grover, Sharang Rajesh Iyer +1
We propose an instrinsic worldsheet description of the ultra-high energy regime of string scattering based on worldsheet symmetries. At very high energies, the fundamental string b…
Black hole Near Horizons through the Looking Glass
Arjun Bagchi, Arkachur Bhattacharya, Sharang Rajesh Iyer +1
We show that the near horizon of a generic non-extremal black hole (BH) can be understood in terms of a Carrollian geometry with two null directions, also called a String-Carroll (…
Universal sectors of two-dimensional Carrollian CFTs
Ankit Aggarwal, Arjun Bagchi, Stephane Detournay +3
We revisit modular invariance in two-dimensional Carrollian conformal field theories from a geometric perspective. Focusing on the characters of the induced and highest-weight repr…
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…
