A review on analytical studies in Gravitational Lensing
Abhishek Chowdhuri, Saptaswa Ghosh, Arpan Bhattacharyya
In this study, we review some current studies on Gravitational Lensing for black holes, mainly in the context of general relativity. We mainly focus on the analytical studies relat…
Bath deformations, islands and holographic complexity
Aranya Bhattacharya, Arpan Bhattacharyya, Pratik Nandy +1
Considering a doubly holographic model, we study the evolution of holographic subregion complexity corresponding to deformations of bath state by a relevant scalar operator, which…
Complexity for Open Quantum System
Arpan Bhattacharyya, Tanvir Hanif, S. Shajidul Haque +1
We study the complexity for an open quantum system. Our system is a harmonic oscillator coupled to a one-dimensional massless scalar field, which acts as the bath. Specifically, we…
Renormalized Entanglement Entropy for BPS Black Branes
Arpan Bhattacharyya, S. Shajidul Haque, Alvaro Veliz-Osorio
We compute the renormalized entanglement entropy (REE) for BPS black solutions in , 4d gauged supergravity. We find that this quantity decreases monotonically with the…
