Two-Photon Transport in a Waveguide Coupled to a Cavity with a Two-level System
Two-Photon Transport in a Waveguide Coupled Two-level System
<
2010/10/20
We consider a system where a waveguide is coupled to a cavity embedded with a two-level system
(TLS), and study the effects when a two-photon quantum state is injected into the waveguide. The wave fu...
Unexpected systematic degeneracy in a system of two coupled Gaudin models with homogeneous couplings

2010/10/27
We report an unexpected systematic degeneracy between di erent multiplets in an inversion symmetric system of two coupled Gaudin models with homogeneous couplings, as occurring for example in the cont...
A D-dimensional Markovian open quantum system will undergo quantum jumps between pure
states, if we can monitor the bath to which it is coupled with sufficient precision. In general these jumps, plus...
