Decoding the Imprints of Energy-Momentum Squared Gravity in Neutron Stars with Machine Learning Analysis
Sayantan Ghosh, Premachand Mahapatra, Dipti Deb
Neutron stars (NSs) provide a unique laboratory for testing gravity in the strong-field regime and for searching for deviations from General Relativity (GR). In this work, we inves…
Trace anomaly and interior curvature of neutron stars in energy-momentum squared gravity
Ratikanta Swain, Sayantan Ghosh, Bharat Kumar
In energy-momentum squared gravity (EMSG), the spacetime inside a neutron star is sourced by effective thermodynamic variables that need not coincide with the physical fluid pressu…
Universal Relations and Correlation Analysis of Proto-Neutron Star Properties in Energy-Momentum Squared Gravity
Sayantan Ghosh
Proto-neutron stars (PNSs) are the hot, lepton-rich remnants of the core collapse supernovae, which go through a cooling phase and become cold, stable Neutron stars (NSs). Since PN…
Spacetime Curvature as a Probe of Exotic Core Phases in Neutron Stars within Modified Gravity
Sayantan Ghosh, Bharat Kumar, Subhash Mahapatra
In this study, we investigate the effect of Energy-Momentum Squared Gravity (EMSG) on the curvature of neutron stars (NSs) by using three relativistic mean-field (RMF) equations of…
Exploring Radial Oscillations in Slow Stable and Hybrid Neutron Stars
Sayantan Ghosh, Sailesh Ranjan Mohanty, Tianqi Zhao +1
In the era of gravitational wave astronomy, radial oscillations hold significant potential for not only uncovering the microphysics behind the internal structure but also investiga…
Probing the impact of Delta-Baryons on Nuclear Matter and Non-Radial Oscillations in Neutron Stars
Probit Jyoti Kalita, Pinku Routaray, Sayantan Ghosh +2
The presence of heavy baryons, such as -baryons and hyperons can significantly impact various properties of Neutron Stars (NSs), like oscillation frequencies, dimensionless tida…
Exploring the Macroscopic Properties and Nonradial Oscillations of Proto-Neutron Stars: Effects of Temperature, Entropy, and Lepton Fraction
Sayantan Ghosh, Shahebaj Shaikh, Probit J Kalita +3
Neutron stars (NSs) have traditionally been viewed as cold, zero-temperature entities. However, recent progress in computational methods and theoretical modelling has opened up the…
Exploration of strongly correlated states in SmB6 through a comparison of its two-coil pick-up response to that of Bi2Se3
Sayantan Ghosh, Sugata Paul, Amit Jash +2
Earlier studies on the Kondo insulator SmB6 reveal the presence of a bulk Kondo insulating gap between 30 - 50 K, and the emergence of a conducting surface state only below 4 K. He…
Non-exotic static spherically symmetric thin-shell wormhole solution in gravity
Moreshwar Tayde, Sayantan Ghosh, P. K. Sahoo
In this study, we have conducted an analysis of traversable wormhole solutions within the framework of linear gravity, ensuring that all the energy conditions h…
The Impact of Anisotropy on Neutron Star Properties: Insights from I-f-C Universal Relations
Sailesh Ranjan Mohanty, Sayantan Ghosh, Pinku Routaray +2
This study presents a universal relation for anisotropic neutron stars, called the relation, which accounts for the local anisotropic pressure using the Quasi-Local (QL) Mo…
Investigating Dark Matter-Admixed Neutron Stars with NITR Equation of State in Light of PSR J0952-0607
Pinku Routaray, Sailesh Ranjan Mohanty, H. C. Das +4
The fastest and heaviest pulsar, PSR J0952-0607, with a mass of , has recently been discovered in the disk of the Milky Way Galaxy. In response to this dis…
Unstable Anisotropic Neutron Stars: Probing the Limits of Gravitational Collapse
S. R. Mohanty, Sayantan Ghosh, Bharat Kumar
Neutron stars (NSs) are incredibly versatile for studying various important aspects of high-energy and compact-object physics. These celestial objects contain extreme matter at inc…
Radial oscillations in neutron stars from unified hadronic and quarkyonic equation of states

We study radial oscillations in non-rotating neutron stars by considering the unified equation of states (EoSs), which support the 2 M star criterion. We solve the Sturm-Li…
Entangled Quantum States of Magnetic Dipoles
S. Ghosh, T. F. Rosenbaum, G. Aeppli +1
Free magnetic moments usually manifest themselves in Curie Laws, where weak external magnetic fields produce magnetizations diverging as the reciprocal 1/T of the temperature. for…
Coherent Spin Oscillations in a Disordered Magnet
S. Ghosh, R. Parthasarathy, T. F. Rosenbaum +1
Most materials freeze when cooled to sufficiently low temperature. We find that magnetic dipoles randomly distributed in a solid matrix condense into a spin liquid with spectral pr…
