Single-photon router: Coherent control of multichannel scattering for single photons with quantum interferences

J Lu, L Zhou, LM Kuang, F Nori - Physical Review A, 2014 - APS
We propose a single-photon router using a single atom with an inversion center coupled to
quantum multichannels made of coupled-resonator waveguides. We show that the …

Topological protection from exceptional points in Weyl and nodal-line semimetals

J González, RA Molina - Physical Review B, 2017 - APS
We investigate the topological protection of surface states in Weyl and nodal-line
