Electrovacuum solutions in non-local gravity
Karan Fernandes, Arpita Mitra
We consider the coupling of the electromagnetic field to a non-local gravity theory comprising of the Einstein-Hilbert action in addition to a non-local term as…
Cosmological implications of shift symmetric Galileon field
Rabin Banerjee, Sumanta Chakraborty, Arpita Mitra +1
A ghost-free metric formulation of the recently proposed covariant Galileon model \cite{RPgal} which retains the internal shift symmetry has been constructed. This presents a new r…
Gravitational anomalies on the Newton-Cartan background
Karan Fernandes, Arpita Mitra
We derive the trace and diffeomorphism anomalies of the Schrödinger field minimally coupled to the Newton-Cartan background using Fujikawa's path integral approach. This approach i…
General algorithm for non-relativistic diffeomorphism invariance
Rabin Banerjee, Arpita Mitra, Pradip Mukherjee
An algorithmic approach towards the formulation of non-relativistic diffeomorphism invariance has been developed which involves both matter and gauge fields. A step by step procedu…
A new formulation of non-relativistic diffeomorphism invariance
Rabin Banerjee, Arpita Mitra, Pradip Mukherjee
We provide a new formulation of nonrelativistic diffeomorphism invariance. It is generated by localising the usual global Galilean Symmetry. The correspondence with the type of dif…
