Cavity-Induced Suppression of Entanglement and Enhancement of Quantum Discord
Shagun Kaushal, Harkirat Singh Sahota
We study correlations between two Unruh-DeWitt detectors coupled to a scalar field in a cylindrical cavity. Boundary conditions strongly modify the detector-correlation dynamics re…
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…
