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…
Probing Chaos in Schwarzschild-de Sitter Spacetime: The Role of Black Hole and Cosmological Horizons
Surojit Dalui, Soumya Bhattacharya, Chiranjeeb Singha
In this paper, we study the motion of a massless, chargeless particle in Schwarzschild-de Sitter spacetime, revealing exponential radial growth and potential chaos in an integrable…
