Spectral Distribution of Exceptional Points in Lattices with Localized Loss
J. R. Silva
We explore the existence and stability of exceptional points (EPs) in finite waveguide arrays subject to single-site dissipation. We show that the EP landscape is dictated by a geo…

Anomalous transparency of photons in non-Markovian coupled waveguides
J. R. Silva, P. A. Brandão
The transmission of photons through a pair of coupled single-mode waveguides is studied in detail. It is assumed that one of the waveguides is coupled to a non-Markovian reservoir,…
