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 $…
Higher Spin Gravity in and Folds on Fermi Surface
Suvankar Dutta, Debangshu Mukherjee, Sanhita Parihar
In this paper, we introduce new sets of boundary conditions for higher spin gravity in where the boundary dynamics of spin two and other higher spin fields are governed by…
Higher derivative invariants in four dimensional N=3 Poincare supergravity
Subramanya Hegde, Madhu Mishra, Debangshu Mukherjee +1
In this paper, we use the superconformal approach to derive the higher derivative action for N = 3 Poincare supergravity in four space-time dimensions. We first study the coupling…

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…
From 2d Droplets to 2d Yang-Mills
Arghya Chattopadhyay, Suvankar Dutta, Debangshu Mukherjee +1
We establish a connection between time evolution of free Fermi droplets and partition function of \emph{generalised} \emph{q}-deformed Yang-Mills theories on Riemann surfaces. Clas…
Quantum Mechanics of Plancherel Growth
Arghya Chattopadhyay, Suvankar Dutta, Debangshu Mukherjee +1
Growth of Young diagrams, equipped with Plancherel measure, follows the automodel equation of Kerov. Using the technology of unitary matrix model we show that such growth process i…
Hyperscaling violation, quasinormal modes and shear diffusion
Debangshu Mukherjee, K. Narayan
We study quasinormal modes of shear gravitational perturbations for hyperscaling violating Lifshitz theories, with Lifshitz and hyperscaling violating exponents and . The lo…
Notes on hyperscaling violating Lifshitz and shear diffusion
Kedar S. Kolekar, Debangshu Mukherjee, K. Narayan
We explore in greater detail our investigations of shear diffusion in hyperscaling violating Lifshitz theories in arXiv:1604.05092 [hep-th]. This adapts and generalizes the membran…
Hyperscaling violation and the shear diffusion constant
Kedar S. Kolekar, Debangshu Mukherjee, K. Narayan
We consider holographic theories in bulk -dimensions with Lifshitz and hyperscaling violating exponents at finite temperature. By studying shear gravitational modes in…
AdS plane waves, entanglement and mutual information
Debangshu Mukherjee, K. Narayan
