Pulsar as a Weber detector of gravitational waves and a probe to its internal phase transitions

Partha Bagchi, Oindrila Ganguly, Biswanath Layek +2

It is believed that cores of neutron stars provide a natural laboratory where exotic high baryon density QCD phases may exist.The theoretically well established {\it neutron superf…

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…

Pulsars as Weber gravitational wave detectors

Arpan Das, Shreyansh S. Dave, Oindrila Ganguly +1

A gravitational wave passing through a pulsar will lead to a variation in the moment of inertia of the pulsar affecting its rotation. This will affect the extremely accurately meas…

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…

A realisation of Lorentz algebra in Lorentz violating theory

Oindrila Ganguly

A Lorentz non-invariant higher derivative effective action in flat spacetime, characterised by a constant vector, can be made invariant under infinitesimal Lorentz transformations…

Lorentz-preserving fields in Lorentz-violating theories

Oindrila Ganguly, Debashis Gangopadhyay, Parthasarathi Majumdar

We identify a fairly general class of field configurations (of spins 0, 1/2 and 1) which preserve Lorentz invariance in effective field theories of Lorentz violation characterized…
