algebra and the dual theory of 3D asymptotically flat higher spin gravity
Nabamita Banerjee, Arindam Bhattacharjee, Surajit Biswas +2
BMS algebra in three spacetime dimensions can be deformed into a two parameter family of algebra known as algebra. For , we show that other than , no other $…
JT gravity from holographic reduction of 3D asymptotically flat spacetime
Arindam Bhattacharjee, Muktajyoti Saha
We attempt to understand the CFT structure underlying (2+1)D gravity in flat spacetime via dimensional reduction. We observe that under superrotation, the hyperbolic (and dS$_2…
Dual Theory for maximally extended flat Supergravity
Nabamita Banerjee, Arindam Bhattacharjee, Surajit Biswas +1
Maximally extended dimensional flat Supergravity theories exist for a class of super-Poincaré algebras for arbitrary . They have rich asymptotic st…
A Matrix Model with BMS Constraints
Arindam Bhattacharjee, Neetu
Our goal is to find a matrix model with constraints built in. These constraints are imposed through Loop equations. We solve them using a free field realisation of the alge…
Asymptotic Symmetry and Classical holographic dual of supergravity
Arindam Bhattacharjee
We consider minimal supergravity on (2+1)dimensional de-Sitter background. We fix the fall-off conditions for gravitini fields in order to fix the asymptotic phase space. Using the…
Classical Soft Theorem in the AdS-Schwarzschild spacetime in small cosmological constant limit
Nabamita Banerjee, Arindam Bhattacharjee, Arpita Mitra
We have studied scattering of a probe particle by a four dimensional AdS-Schwarzschild black hole at large impact factor. Our analysis is consistent perturbatively to leading order…
