Closed timelike curves in modified theories of gravity

Agnik Sen Roy, Sashideep Gutti, Shailesh Kulkarni

We study closed timelike curves (CTCs) in three rotating spacetimes arising in modified gravity: the tidally charged braneworld black hole, the Kerr-Newman black hole in Rastall gr…

Generation and purification of excited spacetimes using Schwarzian derivative

Rakesh K Jha, Akhil U Nair, Prasant Samantray +1

In this article, we use the expression of the Schwarzian derivative to set up differential equations to find answers to three fundamental questions in the context of QFT in curved…

Four inequivalent paths to Thermality in Minkowski spacetime

Rakesh K Jha, Akhil U Nair, Prasant Samantray +1

We investigate thermal behaviour in quantum fields by analysing a hierarchy of null-shifted Rindler wedges in Minkowski spacetime. Starting from the Minkowski vacuum restricted to…

Complexity Growth in Black Holes: A Comparison of the Volume and Action Proposals

Suraj Maurya, Sashideep Gutti, Rahul Nigam +1

In this article, we investigate the late-time growth of holographic complexity, defined via the complexity-volume (CV) and complexity-action (CA) prescriptions, for BTZ, Schwarzsch…

Selective Thermalization, Chiral Excitations, and a Case of Quantum Hair in the Presence of Event Horizons

Akhil U Nair, Rakesh K. Jha, Prasant Samantray +1

The Unruh effect is a well-understood phenomenon, where one considers a vacuum state of a quantum field in Minkowski spacetime, which appears to be thermally populated for a unifor…

Maximal hypersurfaces and aspects of volume of the Kerr family of black holes

Suraj Maurya, Sashideep Gutti, Rahul Nigam

In Schwarzschild spacetime, Reinhart (1973) has shown the hypersurface (the subscript stands for "Reinhart") to be a maximal hypersurface. This Reinhart radius p…
