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…
Stochastic Variability of Binary Accretion
Akhil Nair, Jonathan Zrake
We measure the power spectral density (PSD) of the accretion rate time series in an unequal mass (q = 0.2) binary surrounded by a circumbinary gas disk, using very high-resolution…
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…
