Wigner Function of Observed Quantum Systems
Juan Camilo López Carreño
The Wigner function was introduced as an attempt to describe quantum-mechanical fields with the tools inherited from classical statistical mechanics. In particular, it is widely us…

Pulsed Quantum Excitation
Juan Camilo López Carreño
A two-level system (2LS) is the most fundamental building block of matter. Its response to classical light is well known, as it converts pulses of coherent light into antibunched e…

Conventional and unconventional photon statistics
E. Zubizarreta Casalengua, J. C. López Carreño, F. P. Laussy +1
We show how the photon statistics emitted by a large variety of light-matter systems under weak coherent driving can be understood, to lowest order in the driving, in the framework…
