Revival of transport reciprocity via quantum interference in asymmetric nonlinear devices
Rupak Bag, Dibyendu Roy
Structural asymmetry combined with optical nonlinearity often leads to nonreciprocal light transport. We explore the mechanism by which 1-photon interference effects can revive rec…
Detection of long-range coherence in driven hot atomic vapors by spin noise spectroscopy
Rupak Bag, Sayari Majumder, Saptarishi Chaudhuri +1
We study intriguing dynamical features of hot Rubidium atoms driven by two light fields. The fields resonantly drive multiple Zeeman states within two hyperfine levels, yielding a…
Nonreciprocal electrical transport in linear systems with balanced gain and loss in the bulk
Rupak Bag, Dibyendu Roy
We investigate electrical transport in a quantum wire of sites connected to an equal number of sources and drains of charges in bulk. Each source and drain injects an…
Quantum light-matter interactions in structured waveguides
Rupak Bag, Dibyendu Roy
We explore special features of quantum light-matter interactions inside structured waveguides due to their finite bandwidth, band edges, and non-trivial topological properties. We…
