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…

Quantum noise induced nonreciprocity for single photon transport in parity-time symmetric systems
Dibyendu Roy, G. S. Agarwal
We show nonreciprocal light propagation for single-photon inputs due to quantum noise in coupled optical systems with gain and loss. We consider two parity-time () sy…

Many-body quantum chaos in mixtures of multiple species
Vijay Kumar, Dibyendu Roy
We study spectral correlations in many-body quantum mixtures of fermions, bosons, and qubits with periodically kicked spreading and mixing of species. We take two types of mixing,…
