Raychaudhuri Equation and Weyl-Driven Shear: A Weak-Field Approach to Lensing and Gravitational Waves
Madhukrishna Chakraborty, Subenoy Chakraborty
The letter studies phenomena like gravitational wave propagation and gravitational lensing using the celebrated Raychaudhuri equation (RE) in the weak field limit. Newtonian analog…
Quasinormal modes and Grey body factors of Wormholes: From General prescription to Einstein Gauss Bonnet realizations
Madhukrishna Chakraborty, Subenoy Chakraborty
Traversable wormholes are one of the most exciting predictions of General Relativity that offer short-cuts through space-time. However, their feasibility requires the violation of…
Landauer's principle and black hole area quantization
Bijan Bagchi, Aritra Ghosh, Sauvik Sen
This article assesses Landauer's principle from information theory in the context of area quantization of the Schwarzschild black hole. Within a quantum-mechanical perspective wher…
Quantized Area of the Schwarzschild Black Hole: A non-Hermitian Perspective
Bijan Bagchi, Aritra Ghosh, Sauvik Sen
In this work, our aim is to link Bekenstein's quantized form of the area of the event horizon to the Hamiltonian of the non-Hermitian Swanson oscillator which is known to be $\math…
