Evolution of energy density fluctuations in the presence of a magnetic field
Shreyansh S. Dave, Subrata Pal
In this proceeding, we study the evolution of energy density fluctuations in the presence of a static and uniform magnetic field. By numerically solving the relativistic Boltzmann-…
Effects of magnetic field on the evolution of energy density fluctuations
Shreyansh S. Dave, Subrata Pal
We study the effects of a static and uniform magnetic field on the evolution of energy density fluctuations present in a medium. By numerically solving the relativistic Boltzmann-V…
Parametric resonance in abelian and non-abelian gauge fields via space-time oscillations
Shreyansh S. Dave, Sanatan Digal, Vinod Mamale
We study the evolution of abelian electromagnetic as well as non-abelian gauge fields, in the presence of space-time oscillations. Analysis of the time evolution of…
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,…
Field excitation in fuzzy dark matter near a strong gravitational wave source
Shreyansh S. Dave, Sanatan Digal
The axion-like particles with ultralight mass (eV) can be a possible candidate of dark matter, known as the fuzzy dark matter (FDM). These particles form Bose-Einstei…
Parametric resonance of complex scalar field under spacetime oscillations
Shreyansh S. Dave, Sanatan Digal
In this proceeding, we study time evolution of a complex scalar field, in symmetry broken phase, in presence of oscillating spacetime metric background. We show that spacetime osci…
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…
Initial fluctuations and power spectrum of flow anisotropies in relativistic heavy-ion collisions
Shreyansh S. Dave, Saumia P. S., Ajit M. Srivastava
Flow has emerged as a crucial probe for the properties of the thermalized medium produced in relativistic heavy-ion collisions. The evolution of initial state fluctuations leaves i…
Effects of oscillating spacetime metric background on a complex scalar field and formation of topological vortices
Shreyansh S. Dave, Sanatan Digal
We study the time evolution of a complex scalar field in the symmetry broken phase in the presence of oscillating spacetime metric background. In our (2+1)-dimensional simulations,…
Re-visiting gravitational wave events via pulsars
Minati Biswal, Shreyansh S. Dave, Ajit M. Srivastava
By now many gravitational wave (GW) signals have been detected by LIGO and Virgo, with the waves reaching earth directly from their respective sources. These waves will also travel…
Formation of topological vortices during superfluid transition in a rotating vessel
Shreyansh S. Dave, Ajit M. Srivastava
Formation of topological defects during symmetry breaking phase transitions via the {\it Kibble mechanism} is extensively used in systems ranging from condensed matter physics to t…
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…
Setting Initial Conditions for Inflation with Reaction-Diffusion Equation
Partha Bagchi, Arpan Das, Shreyansh S. Dave +2
We discuss the issue of setting appropriate initial conditions for inflation. Specifically, we consider natural inflation model and discuss the fine tuning required for setting alm…
Effects of magnetic field on the plasma evolution in relativistic heavy-ion collisions
Arpan Das, Shreyansh S. Dave, P. S. Saumia +1
Very strong magnetic fields can arise in non-central heavy-ion collisions at ultrarelativistic energies, which may not decay quickly in a conducting plasma. We carry out relativist…
Towards laboratory detection of topological vortices in superfluid phases of QCD
Arpan Das, Shreyansh S. Dave, Somnath De +1
Topological defects arise in a variety of systems, e.g. vortices in superfluid helium to cosmic strings in the early universe. There is an indirect evidence of neutron superfluid v…
