Accelerated first detection in discrete-time quantum walks using sharp restarts Open
Restart is a common strategy observed in nature that accelerates first-passage processes, and has been extensively studied using classical random walks. In the quantum regime, restart in continuous-time quantum walks (CTQWs) has been shown…

Rehabilitation Exercise Repetition Segmentation and Counting using Skeletal Body Joints Open
Physical exercise is an essential component of rehabilitation programs that improve quality of life and reduce mortality and re-hospitalization rates. In AI-driven virtual rehabilitation programs, patients complete their exercises independ…

Covid-19 for India: A Data Analytics Approach Open
The COVID-19 epidemic has caused a large number of human losses and havoc in the economic, social, societal, and health system around the world. India also severely impacted throughout 34 states. First case reported on: 30 January 2020. As…

Bell's inequality violation by dynamical Casimir photons in a superconducting microwave circuit Open
We study the Bell's inequality violation by dynamical Casimir radiation with pseudospin measurement. We consider a circuit quantum electrodynamical set-up where a relativistically moving mirror is simulated by variable external magnetic fl…

Violation of equivalence in an accelerating atom-mirror system in the generalized uncertainty principle framework Open
We study the spontaneous excitation of a two-level atom in the presence of a perfectly reflecting mirror, when the atom, or the mirror, is uniformly accelerating in the framework of the generalised uncertainty principle (GUP). The quantize…

Dynamics of a composite quantum bouncing ball Open
I construct the state of a quantum particle with internal degree of freedom bouncing on a perfect reflector in presence of gravity. I predict from the result that revival of position expectation is possible for such system.

Preservation of quantum coherence under Lorentz boost for narrow uncertainty wave packets Open
We consider the effect of relativistic boosts on single particle Gaussian\nwave packets. The coherence of the wave function as measured by the boosted\nobserver is studied as a function of the momentum and the boost parameter.\nUsing vario…
