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…
Noncommutative gauge theories and Lorentz symmetry
Rabin Banerjee, Biswajit Chakraborty, Kuldeep Kumar
We explicitly derive, following a Noether-like approach, the criteria for preserving Poincare invariance in noncommutative gauge theories. Using these criteria we discuss the vario…
Screening in three-dimensional QED
E. Abdalla, R. Banerjee
We compute the quark-antiquark potential in three dimensional massive Quantum Electrodynamics. The result indicates that screening prevails for large quark masses, contrary to the…
Generalised Hamiltonian embedding of the Proca model
N. Banerjee, R. Banerjee
We convert the second class Proca model into a first class theory by using the generalised prescription of Batalin, Fradkin and Tyutin. We then show how a basic set of gauge invari…
Quantisation of second class systems in the Batalin-Tyutin formalism
N. Banerjee, R. Banerjee, S. Ghosh
We review the Batalin-Tyutin approach of quantising second class systems which consists in enlarging the phase space to convert such systems into first class. The quantisation of f…
Quantisation of invariant nonlinear sigma model in the Batalin-Tyutin formalism
N. Banerjee, Subir Ghosh, R. Banerjee
We quantise the nonlinear sigma model using the Batalin Tyutin (BT) approach of converting a second class system into first class. It is a {\it nontrivial} application of th…
