State-resolved quantum-information fingerprints of partial dynamical symmetry in the interacting boson model
Dhritimalya Roy
Partial dynamical symmetry (PDS) is an algebraic structure in which a symmetry is neither exact nor fully broken: a subset of eigenstates keeps good quantum numbers and stays solva…
Geodesic Motion and Particle Confinements in Cylindrical Wormhole Spacetime: Exploring Closed Timelike Curves
Dhritimalya Roy, Ayanendu Dutta, Subenoy Chakraborty
In this study, the geodesic motion of a test particle along with its confinement is investigated within Cylindrically Symmetric Wormhole spacetime admitting to Closed Timelike Curv…
Investigating Evolving Wormholes in Gravity
Dhritimalya Roy, Ayanendu Dutta, Bikram Ghosh +1
The present work examines whether evolving wormhole solution is possible or not in modified gravity theory. In the background of inhomogeneous FLRW type wormhole configura…
Evolving wormhole formation in dRGT massive gravity
Ayanendu Dutta, Dhritimalya Roy, Subenoy Chakraborty
In this study, we have examined the evolving wormhole solution within Einstein-massive gravity, considering traceless, barotropic, and anisotropic pressure fluids. We have conducte…
On the role of closed timelike curves and confinement structure around Kerr-Newman singularity
Ayanendu Dutta, Dhritimalya Roy, Subenoy Chakraborty
In this study, the particle motion around the naked singularity and black hole of Kerr-Newman spacetime is investigated with a special attention on the closed timelike orbits. It i…
Does Dynamical Wormhole Evolve From Emergent Scenario?
Dhritimalya Roy, Ayanendu Dutta, Bikram Ghosh +1
In the present work we analyse a dynamical wormhole solution with two fluids system (one isotropic and homogeneous and the other being inhomogeneous and anisotropic in nature) as t…
Particle motion around traversable wormholes: Possibility of closed timelike geodesics
Ayanendu Dutta, Dhritimalya Roy, Subenoy Chakraborty
The present work investigates the general wormhole solution in Einstein gravity with an exponential shape function around an ultrastatic and a finite redshift geometry. The geodesi…
Wormhole formation in massive gravity: An analytic description
Ayanendu Dutta, Dhritimalya Roy, Nihal Jalal Pullisseri +1
The present study analyses the wormhole solution both in the dRGT- massive gravity and Einstein massive gravity. In both the models, the anisotropic pressure solution in…
Does violation of Cosmic No-hair Conjecture guarantee the existence of Wormhole?
Dhritimalya Roy, Ayanendu Dutta, Subenoy Chakraborty
The present work investigates the interrelation between the validity (or violation) of the cosmic no-hair conjecture and the existence (or non-existence) of wormholes, both in Eins…
The role of closed timelike curves in particle motion within Van Stockum space-time: A generalization
Ayanendu Dutta, Dhritimalya Roy, Subenoy Chakraborty
The present work analyses the particle motion in the Van Stockum space-time considering the existence of closed timelike curves. Test particles with or without angular momentum are…
