A Note on Partially Anti-invariant Submanifolds of Kenmotsu Manifolds
Muhammad Shuaib, Cenap Ozel, Meraj A. Khan +1
In this paper, we introduce and investigate partially antiinvariant submanifolds of Kenmotsu manifolds. The integrability of the involved distributions is examined, and conditions…
Magnetic Reconnection and Energy Extraction from a Rotating Black Hole in the Einstein-AdS SU(N)-Nonlinear Sigma Model
Muhammad Israr Aslam, Muhammad Nawaz, Abdul Malik Sultan +3
In the present study, we analyze the power and efficiency of energy extraction via magnetic reconnection in the rotating Einstein-AdS-SU()-NLSM black hole, both in the circular-…
Magnetic Reconnection and Energy Extraction from a Rotating Black Hole in a Four-dimensional Einstein-Gauss-Bonnet Gravity
Abdul Malik Sultan, Muhammad Israr Aslam, Muhammad Nawaz +4
Recently, Comisso and Asenjo proposed a new mechanism for energy extraction based on magnetic reconnection of plasma within the ergosphere. In this paper, we analyze the power and…
Repetitive Penrose Process in Rastall Rotating Black Holes Immersed in Quintessence Dark Energy
Ali Ahmad Sabir, Muhammad Israr Aslam, Abdul Malik Sultan +3
We investigate the repetitive Penrose process in the spacetime of a Rastall rotating black hole surrounded by a quintessence dark energy field. After reviewing the fundamental prop…
