Correlation Harvesting by Unruh--DeWitt Detectors in a Cylindrical Cavity: Entanglement, Mutual Information, and Quantum Discord
Shagun Kaushal, Harkirat Singh Sahota
We study correlations between two Unruh--DeWitt detectors coupled to a massless scalar field confined inside a cylindrical cavity through entanglement negativity, mutual informatio…
Cavity-controlled Inhibition of Decoherence in Accelerated Quantum Detectors
Harkirat Singh Sahota, Shagun Kaushal, Kinjalk Lochan
Vacuum fluctuations of quantum fields provide an unavoidable environment for any quantum system coupled to it. We study the interplay between boundary conditions and acceleration i…
A dynamical systems perspective on the thermodynamics of late-time cosmology
Dipayan Mukherjee, Harkirat Singh Sahota, Swati Gavas
A thermodynamic description of cosmological spacetimes may provide insights into the fundamentals of the cosmic evolution that remain otherwise obscure, similar to `black hole ther…
Non-local correlations of a test quantum field in gravitational collapse
Harkirat Singh Sahota, Suprit Singh, Ashish Pandita
Quantum correlations across the horizon could be pivotal in unveiling the puzzles surrounding quantum aspects of black holes and Hawking radiation. The peaks in the equal time corr…
Unitary quantum matter-bounce in a universe with a positive cosmological constant
Harkirat Singh Sahota, Dipayan Mukherjee, S. Shankaranarayanan
We analyze the Wheeler-DeWitt quantization of a spatially flat Friedmann-Lemaître-Robertson-Walker universe containing pressureless dust and a positive cosmological constant ($Λ> 0…
Exact path integrals on half-line in quantum cosmology with a fluid clock and aspects of operator ordering ambiguity
Vikramaditya Mondal, Harkirat Singh Sahota, Kinjalk Lochan
We perform half-line path integral quantization of flat, homogeneous cosmological models containing a perfect fluid acting as an internal clock, in a dimensi…
Are accelerated detectors sensitive to Planck scale changes?
Harkirat Singh Sahota, Kinjalk Lochan
One of the foremost concerns in the analysis of quantum gravity is whether the locations of classical horizons are stable under a full quantum analysis. In principle, any classical…
Imprints of the operator ordering ambiguity on the dynamics of perfect fluid dominated quantum universe
Harkirat Singh Sahota
Sharply peaked quantum states are conjectured to be conducive to the notion of a quantum-corrected spacetime. We investigate this conjecture for a flat-FLRW model with perfect flui…
