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…

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…
