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…
Time-resolved and Superradiantly Amplified Unruh Effect
Akhil Deswal, Navdeep Arya, Kinjalk Lochan +1
We identify low-acceleration conditions under which the Unruh effect manifests as an early superradiant burst in a collection of excited atoms. The resulting amplified Unruh signal…
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…
A nested sequence of inequivalent Rindler vacua : Universal Relic Thermality of Planckian origin
Kinjalk Lochan, T. Padmanabhan
The Bogoliubov transformation connecting the standard inertial frame mode functions to the standard mode functions defined in the Rindler frame , leads to the result that the…
