Few-photon transport in low-dimensional systems
P. Longo, P. Schmitteckert, and K. Busch (2011)
Physical Review A 83:063828
We present a detailed analysis of the dynamics of photon transport in waveguiding systems in the presence of a two-level system. In these systems, quantum interference effects generate a strong...

By using direct laser writing into a novel commercially available photoresist and a silicon-double-inversion procedure followed by tempering of the silicon structures, we realize high-quality...
Few-Photon Transport in Low-Dimensional Systems: Interaction-Induced Radiation Trapping
Paolo Longo, Peter Schmitteckert, and Kurt Busch (2010)
Physical Review Letters 104:023602
We present a detailed analysis of the dynamics of photon transport in waveguiding systems in the presence of a two-level system. In these systems, quantum interference effects generate a strong...
