Revival of transport reciprocity via quantum interference in asymmetric nonlinear devices
Rupak Bag, Dibyendu Roy
The paper investigates how quantum interference can restore reciprocal photon transport in asymmetric nonlinear optical setups by analyzing two-photon scattering in waveguide–atom…

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…
