Selective enhancement of quantum decay channels
Pritam Nanda, Kinjalk Lochan
In the decay of quantum particles under field theoretic consideration, the decay rate is typically a convolution of the density of modes the primary field is allowed to decay into…
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…
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…
Quantum Gravity signatures in late time Universe
Ankit Dhanuka, Kinjalk Lochan
In the cosmological settings, Quantum Gravity effects are typically understood to be limited towards very early phase of the universe, namely in the pre-inflationary era, with limi…
Analyzing quantum gravity spillover in the semiclassical regime
Harkirat Singh Sahota, Kinjalk Lochan
One of the standard approaches of incorporating the quantum gravity (QG) effects into the semiclassical analysis is to adopt the notion of a quantum-corrected spacetime arising fro…
