Spinning test particles in a weak gravitational wave and the memory effect
Ritwik Acharyya, Shailesh Kumar, Sayan Kar
In this work, we investigate the worldline deviation of spinning test particles in a weak gravitational wave (GW) spacetime. Within the pole-dipole approximation and the Tulczyjew…
Displacement memory in regular black hole spacetimes
Ritwik Acharyya, Sayan Kar
Displacement memory, induced by a wave pulse in a regular black hole spacetime, is studied using geodesic (timelike) separation and geodesic deviation. The presence of the wave pul…
Spectroscopy of excited quarkonium states in the light-front quark model
Ritwik Acharyya, Satyajit Puhan, Narinder Kumar +1
We have investigated the ground state (), radially excited states () and () along with the orbitally excited state () for the heavy charmonia () and botto…
Quark spin-orbit correlations in spin-0 and spin-1 mesons using the light-front quark model
Ritwik Acharyya, Satyajit Puhan, Harleen Dahiya
We have investigated the spin-orbital angular momentum correlations for the active quark inside the light and heavy mesons for both the spin-0 and spin-1 cases. These correlations…
Modelling Einstein cluster using Einasto profile
Ritwik Acharyya, Pritam Banerjee, Sayan Kar
We demonstrate a general relativistic approach to model dark matter halos using the Einstein cluster, with the matter stress-energy generated by collisionless particles moving on c…
