Null reduction and dynamical realization of Carrollian conformal symmetries
Ashis Saha, Rabin Banerjee, Sunandan Gangopadhyay
We start from a Lorentzian action in a deformed light-cone background and applying the method of null reduction leads to a Carrollian action in one lower spacetime dimensions. We a…

Gauge interactions and the Galilean limit
Ashis Saha, Rabin Banerjee, Sunandan Gangopadhyay
The gauge invariant minimal couplings for a class of relativistic free matter fields with global symmetry (related to usual charge conservation) have been obtained by incorporating…

SVD Entanglement Entropy of Chiral Dirac Oscillators
Yuvraj Singh, Rabin Banerjee
We discuss the SVD entanglement entropy, which has recently come up as a successor to the pseudo entropy. This paper is a first of-its-kind application of SVD entanglement entropy…
