Generation and purification of excited spacetimes using Schwarzian derivative
Rakesh K Jha, Akhil U Nair, Prasant Samantray +1
The paper uses the Schwarzian derivative to formulate differential equations that identify two‑dimensional spacetime regions with thermal particle spectra, determine parent spaceti…
Thermality Breakdown in Null-Shifted Rindler Wedges
Rakesh K Jha
We investigate the behaviour of quantum fields in null-shifted Rindler wedges and analyse the particle spectra perceived by accelerated observers associated with these null deforma…
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…
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…
