The leading-soft cubic graviton self-interaction on the black-hole horizon
Ayanendu Dutta
We expand the Einstein-Hilbert action to cubic order about the Schwarzschild horizon, in the even Regge-Wheeler gauge of the Gaddam-Groenenboom-'t~Hooft (GGV) near-horizon framewor…
Quantum Simulation of Bound and Resonant Doubly-Bottom Tetraquark
Ayanendu Dutta
We present the first quantum-simulation study of bound and resonant doubly-bottom tetraquark states within a QCD-inspired chiral quark model. An effective four-quark Hamiltonian is…
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…
Properties of black hole exterior fermions in spinfoam
Ayanendu Dutta
We discuss fermion tunneling from the black hole exterior to white hole exterior geometry using the spin foam technique in background-independent Loop Quantum Gravity. The fermion…
