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…

Leading and beyond leading-order spectral form factor in chaotic quantum many-body systems across all Dyson symmetry classes

Vijay Kumar, Tomaž Prosen, Dibyendu Roy

We show the emergence of random matrix theory (RMT) spectral correlations in the chaotic phase of generic periodically kicked interacting quantum many-body systems by analytically…

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…

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,…
