Fermionic Bell violation in the presence of background electromagnetic fields in the cosmological de Sitter spacetime

Ali, M.S.; Bhattacharya, S.; Chakrabortty, S.; Kaushal, S. (2022-08-01)

The violation of the Bell inequality for Dirac fermions is investigated in the cosmological de Sitter spacetime, in the presence of background electromagnetic fields of constant strengths. The orthonormal Dirac mode functions ...
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 ...
