Gravitational-wave signatures of spinning particles around rotating hairy black holes
Surojit Dalui, Xian-Hui Ge
We study how the spin of a compact secondary and a gravitational-decoupling deformation of the Kerr geometry are imprinted on gravitational waves from strong-field eccentric motion…
Spin-Hair Induced Chaos of Spinning Test Particles in Rotating Hairy Black Holes
Surojit Dalui, Xian-Hui Ge
We investigate the finite-time instability of massive spinning test particles around a rotating hairy black hole generated through gravitational decoupling. The particle motion is…
Chaotic Dynamics in Extremal Black Holes: A Challenge to the Chaos Bound
Surojit Dalui, Chiranjeeb Singha, Krishnakanta Bhattacharya
We investigate chaotic dynamics in extremal black holes by analyzing the motion of massless particles in both Reissner-Nordström and Kerr geometries. Two complementary approaches (…
Chaotic Imprints in Gravitational Waves from Extreme-Mass-Ratio-Inspirals Embedded in Dark Matter Halo
Surajit Das, Surojit Dalui, Bum-Hoon Lee +1
We investigate imprints of chaos in gravitational waves from extreme-mass-ratio inspirals configuration, where a stellar massive object, confined in an external potential as a harm…
Extreme-Mass-Ratio Inspirals Embedded in Dark Matter Halo: Existence of Homoclinic Orbit and Horizon-Induced Chaos
Surajit Das, Surojit Dalui, Bum-Hoon Lee +1
We study the existence of homoclinic orbit and the onset of chaotic motion for a massive particle moving around a Schwarzschild-like black hole embedded in a Dehnen-(1,4,5/2) type…
Dynamical analog spacetimes from nonlinear perturbations in a topological material
Surajit Das, Surojit Dalui, Hrishit Banerjee +1
Emergent spacetime analogs in condensed matter systems have opened a fascinating window into simulating aspects of gravitational physics in controlled laboratory environments. In t…
