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…

Detecting winding and Chern numbers in topological matter using spectral function
Kiran Babasaheb Estake, Dibyendu Roy
We propose a method to directly probe bulk topological quantum numbers in topological matter by measuring the momentum-space single-particle spectral function (SPSF). Angle-resolve…

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…
