Unravelling Entanglement (2005)
Carvalho, André R. R., Busse, Marc, Brodier, Olivier, Viviescas, Carlos, Buchleitner, Andreas
We show that the time evolution of entanglement under incoherent environment coupling can be faithfully recovered by monitoring the system according to a suitable measurement scheme.
Semiclassical propagator of the Wigner function (2005)
Dittrich, Thomas, Sandoval, Luis, Viviescas, Carlos
Propagation of the Wigner function is studied on two levels of semiclassical propagation, one based on the van-Vleck propagator, the other on phase-space path integration. Leading quantum corrections...
Quantum theory of multimode fields: Applications to optical resonators (2003)
Viviescas, Carlos, Hackenbroich, Gregor
A recently developed technique for the system--and--bath quantization of open optical cavities is applied to three resonator geometries: A one dimensional dielectric, a Fabry--Perot resonator, and a...
Quantum statistics of overlapping modes in open resonators (2003)
Hackenbroich, Gregor, Viviescas, Carlos, Haake, Fritz
We study the quantum dynamics of optical fields in weakly confining resonators with overlapping modes. Employing a recently developed quantization scheme involving a discrete set of resonator modes...
