Cosmology meets cohomology
Shounak De, Andrzej Pokraka
The cosmological polytope and bootstrap programs have revealed interesting connections between positive geometries, modern on-shell methods and bootstrap principles studied in the…
On unitarity of the Coon amplitude
Rishabh Bhardwaj, Shounak De, Marcus Spradlin +1
The Coon amplitude is a one-parameter deformation of the Veneziano amplitude. We explore the unitarity of the Coon amplitude through its partial wave expansion using tools from …
Correlators of Four Light-Ray Operators in CCFT
Shounak De, Yangrui Hu, Akshay Yelleshpur Srikant +1
Building on results in arXiv:2203.04255, we compute the correlator of four gluon light-ray operators in celestial CFT. We find that it is described by Fox H-functions and generaliz…
Beyond-Newtonian dynamics of a planar circular restricted three-body problem with Kerr-like primaries
Shounak De, Suparna Roychowdhury, Roopkatha Banerjee
The dynamics of the planar circular restricted three-body problem with Kerr-like primaries in the context of a beyond-Newtonian approximation is studied. The beyond-Newtonian poten…
Gravity dual of Navier-Stokes equation in a rotating frame through parallel transport
Sumit Dey, Shounak De, Bibhas Ranjan Majhi
The fluid-gravity correspondence documents a precise mathematical map between a class of dynamical spacetime solutions of the Einstein field equations of gravity and the dynamics o…
Quantum gravity as an emergent phenomenon
Shounak De, Tejinder P. Singh, Abhinav Varma
There ought to exist a reformulation of quantum theory which does not depend on classical time. To achieve such a reformulation, we introduce the concept of an atom of space-time-m…
Effective metric in fluid-gravity duality through parallel transport: a proposal
Shounak De, Sumit Dey, Bibhas Ranjan Majhi
The incompressible Navier-Stokes (NS) equation is known to govern the hydrodynamic limit of essentially any fluid and its rich non-linear structure has critical implications in bot…
Fluid description of gravity on a timelike cut-off surface: beyond Navier-Stokes equation
Shounak De, Bibhas Ranjan Majhi
Over the past few decades, a host of theoretical evidence have surfaced that suggest a connection between theories of gravity and Navier-Stokes (NS) equation of fluid dynamics. It…
