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…
Hawking Temperature of Massive Charged Ads Black Hole: a Topological Treatment
Surajit Mandal, Surajit Das
In this work, we investigate the Hawking temperature of a charged Ads black hole (spherically symmetric) on the basis of a completely topological method introduced by Robson, Villa…
Buchdahl stars and bounds with cosmological constant
Christian G. Boehmer, Naresh Dadhich, Surajit Das
The Schwarzschild interior solution, when combined with the assumption of a finite central pressure, leads to the well-known Buchdahl bound. This bound establishes an upper limit o…
Near-horizon chaos beyond Einstein gravity
Surajit Das, Surojit Dalui, Rickmoy Samanta
We investigate chaos in the dynamics of massless particles near the horizon of static spherically symmetric black holes in two well-motivated models of gravity. In both thes…
Unveilling Chaos in Particle Motion: Analyzing the Impact of Horizon in Gravity
Surajit Das, Surojit Dalui
This article is devoted to investigate the effects of theory in the dynamics of a massless particle near the horizon of a static spherically symmetric (SSS) black hole. Deri…
