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…
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…
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…
