Covariant Effective Action for Generalized Proca Theories
Sukanta Panda, Abbas Tinwala, Archit Vidyarthi
We investigate quantum stability of the generalised Proca theories in curved spacetime treating gravity as a dynamical field. To compute the quantum gravitational corrections we ev…
Higher Derivative Scalar Tensor Theory in Unitary Gauge
Pawan Joshi, Sukanta Panda
Ostrogradsky instability generally appears in nondegenerate higher-order derivative theories and this issue can be resolved by removing any existing degeneracy present in such theo…
Asymptotic Symmetry of Four Dimensional Einstein-Yang-Mills and Einstein-Maxwell Theory
Nabamita Banerjee, Tabasum Rahnuma, Ranveer Kumar Singh
Asymptotic symmetry plays an important role in determining physical observables of a theory. Recently, in the context of four dimensional asymptotically flat pure gravity and $\mat…
Equivalence of JT Gravity and Near-extremal Black Hole Dynamics in Higher Derivative Theory
Nabamita Banerjee, Taniya Mandal, Arnab Rudra +1
Two derivative Jackiw Teitelboim gravity theory captures the near horizon dynamics of higher dimensional near extremal black holes, which is governed by a Schwarzian action at the…
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…
Recursion relations for scattering amplitudes with massive particles II: massive vector bosons
Sourav Ballav, Arkajyoti Manna
Using the recently introduced recursion relations with covariant massive-massless shift, we study tree-level scattering amplitudes involving a pair of massive vector bosons and an…
Interaction Between AdS Black Hole Molecules
Suvankar Dutta, Gurmeet Singh Punia
We take a bottom-up approach to find the interaction potential between the black hole molecules under mean-field approximation. We start with the equation of state of dyonic…
Spinning amplitudes from scalar amplitudes
Mahesh KN Balasubramanian, Raj Patil, Arnab Rudra
We provide a systematic method to compute tree-level scattering amplitudes with spinning external states from amplitudes with scalar external states in arbitrary spacetime dimensio…
A Unitary Matrix Model for -deformed Plancherel Growth
Suvankar Dutta, Debangshu Mukherjee, Neetu +1
In this paper we construct a unitary matrix model that captures the asymptotic growth of Young diagrams under -deformed Plancherel measure. The matrix model is a analog of G…
Covariant Effective Action for Scalar-Tensor Theories of Gravity
Sandeep Aashish, Sukanta Panda, Abbas Altafhussain Tinwala +1
We develop the calculation of the divergent part of one-loop covariant effective action for scalar fields minimally and non-minimally coupled to gravity using the generalized Schwi…
New phase in Chern-Simons theory on lens space
Kushal Chakraborty, Suvankar Dutta
We consider Chern-Simons theory on in Seifert framing and write down the partition function as a unitary matrix model. In the large and large limit the eigen…
Soft Photon theorem in the small negative cosmological constant limit
Nabamita Banerjee, Karan Fernandes, Arpita Mitra
We study the effect of electromagnetic interactions on the classical soft theorems on an asymptotically AdS background in 4 spacetime dimensions, in the limit of a small cosmologic…
