Non-Lorentzian chaos and cosmological holography

Bagchi, A.; Chakrabortty, S.; Grumiller, D.; Radhakrishnan, B.; Riegler, M.; Sinha, A. (2022-08-18)

We study chaos in non-Lorentzian field theories, specifically Galilean and Carrollian conformal field theories in two dimensions. In a large central charge limit, we find that the Lyapunov exponent saturates the bound on ...
Rindler physics on the string worldsheet

Bagchi, A.; Banerjee, A.; Chakrabortty, S. (2021-07-25)

We construct the tensionless limit of bosonic string theory in terms of a family of worldsheets with increasing acceleration and show that the null string emerges in the limit of infinite acceleration when the Rindler ...
