Energy extraction from a Kerr-Bardeen-Letelier black hole by Comisso-Asenjo Mechanism
Bijendra Kumar Vishvakarma, Dharm Veer Singh, Sanjay Siwach
We explore the energy extraction from a Kerr-like regular black hole coupled with a cloud of strings (CoS) via the Comisso-Asenjo mechanism. We study the effects of the black hole…
Operator-Level Quantum-Classical Correspondence in Relativistic Quantum Theory and Curved Spacetime
Pankaj Sheoran, Gopal Kashyap, Sanjay Siwach
In a recent work \cite{Shaikh:2026nsi}, it was shown that for a non-relativistic particle, the operator equations of motion can be cast in the same differential form as Newton's eq…
Strong Gravitational Lensing by Bardeen Black Hole in Cloud of Strings
Bijendra Kumar Vishvakarma, Shubham Kala, Sanjay Siwach
We investigate the gravitational lensing by Bardeen black hole in cloud of strings (CoS) in strong field limit. The effect of CoS parameter has been outlined in comparison with…
Parameter estimation of the Bardeen-Kerr black hole in cloud of strings using shadow analysis
Bijendra Kumar Vishvakarma, Dharm Veer Singh, Sanjay Siwach
We consider the rotating generalization of the Bardeen black hole solution in the presence of cloud of strings (CoS). The parameter space for which the black hole horizon exists is…
Shadows and quasinormal modes of the Bardeen black hole in cloud of strings
Bijendra Kumar Vishvakarma, Dharm Veer Singh, Sanjay Siwach
We investigate the black hole (BH) solution of the Einstein's gravity coupled with non-linear electrodynamics (NED) source in the background of a cloud of strings. We analyze the h…
Motion of charged and spinning particle influenced by dark matter field surrounding a charged dyonic black hole
Sanjar Shaymatov, Pankaj Sheoran, Sanjay Siwach
We investigate the motion of massive charged and spinning test particles around a charged dyonic black hole spacetime surrounded by perfect fluid scalar dark matter field. We obtai…
