Equation of State Parameters for Fluid of Stringy Extended Objects in Cosmology with Cosmological Constant
Soon-Tae Hong, Bum-Hoon Lee
We construct the strong energy conditions (SECs) for both massive and massless stringy extended objects in the higher dimensional cosmology (HDC) with cosmological constant . E…
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…
Charged traversable wormholes: charge without charge
Hyeong-Chan Kim, Sung-Won Kim, Bum-Hoon Lee +1
We present and investigate charged wormhole solutions of the Einstein-Maxwell equations supported by anisotropic matter fields, with the purpose of establishing their physical plau…
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…
