Hawking radiation from acoustic black holes in hydrodynamic flow of electrons
Shreyansh S. Dave, Oindrila Ganguly, Saumia P. S. +1
Acoustic black holes are formed when a fluid flowing with subsonic velocities, accelerates and becomes supersonic. When the flow is directed from the subsonic to supersonic region,…
Hawking radiation from acoustic black holes in relativistic heavy ion collisions
Arpan Das, Shreyansh S. Dave, Oindrila Ganguly +1
We propose a new analogue model of gravity - the evolving quark gluon plasma (QGP) produced in relativistic heavy ion collisions. This quark gluon plasma is the "most inviscid" flu…
Acoustic Hawking radiation from an evolving horizon in a dynamical analogue spacetime
Oindrila Ganguly
Our knowledge of dynamical black holes suffers from a lack of observational insight. In an analogue model of gravity, we can design a longitudinally symmetric dynamical acoustic bl…
Acoustic superradiance in a slightly viscous fluid
Oindrila Ganguly
The acoustic analogue of the geometry of curved spacetime realised in a classical fluid becomes Lorentz violating in the presence of viscosity. We study how this effective Lorentz…
Intertial Frame Dragging in an Acoustic Analogue spacetime
Chandrachur Chakraborty, Oindrila Ganguly, Parthasarathi Majumdar
We report an incipient exploration of the Lense-Thirring precession effect in a rotating \textit{acoustic analogue black hole} spacetime. An exact formula is deduced for the preces…
