Emergent non-Markovianity in time-delayed waveguide QED
Debsuvra Mukhopadhyay, Stuart J. Masson
Quantum systems are invariably coupled to a surrounding environment. A common theoretical method to simplify the problem is to trace over the environment under a Markov approximati…
Coupling Quantum Antennas to Fibers and Waveguides
Girish S. Agarwal, Debsuvra Mukhopadhyay
We present a brief overview of the transport of quantum light across a one-dimensional waveguide which is integrated with a periodic string of quantum-scale dipoles. We demonstrate…
Ultralow threshold bistability and generation of long-lived mode in a dissipatively coupled nonlinear system: application to magnonics
Jayakrishnan M. P. Nair, Debsuvra Mukhopadhyay, Girish S. Agarwal
The prospect of a system possessing two or more stable states for a given excitation condition is of topical interest with applications in information processing networks. In this…
Enhanced sensing of weak anharmonicities through coherences in dissipatively coupled anti-PT symmetric systems
Jayakrishnan M. P. Nair, Debsuvra Mukhopadhyay, G. S. Agarwal
In the last few years, the great utility of PT-symmetric systems in sensing small perturbations has been recognized. Here, we propose an alternate method relevant to dissipative sy…
Transparency in a periodic chain of quantum emitters strongly coupled to a waveguide
Debsuvra Mukhopadhyay, Girish S. Agarwal
We demonstrate the emergence of transparent behavior in a chain of periodically spaced non-identical quantums emitters coupled to a waveguide, in the special case when the inter-at…
Multiple Fano interferences due to waveguide-mediated phase-coupling between atoms
Debsuvra Mukhopadhyay, Girish S. Agarwal
We examine quantum interference effects due to absorption and emission from multiple atoms coupled to a waveguide and highlight the modifications they entail in regards to single-p…
