Megier N, Strunz W, Viviescas C, Luoma K
Phys Rev Lett . 2018 May; 120(15):150402. PMID: 29756890
We derive a family of Gaussian non-Markovian stochastic Schrödinger equations for the dynamics of open quantum systems. The different unravelings correspond to different choices of squeezed coherent states, reflecting different...

Viviescas C, Guevara I, Carvalho A, Busse M, Buchleitner A
Phys Rev Lett . 2011 Jan; 105(21):210502. PMID: 21231276
We use quantum diffusive trajectories to prove that the time evolution of two-qubit entanglement under spontaneous emission can be fully characterized by optimal continuous monitoring. We analytically determine this optimal...

Carvalho A, Busse M, Brodier O, Viviescas C, Buchleitner A
Phys Rev Lett . 2007 Aug; 98(19):190501. PMID: 17677610
We show that, for experimentally relevant systems, there is an optimal measurement strategy to monitor the time evolution of entanglement under open system dynamics. This suggests an efficient, dynamical characterization...

Dittrich T, Viviescas C, Sandoval L
Phys Rev Lett . 2006 Apr; 96(7):070403. PMID: 16606064
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 to...

Hackenbroich G, Viviescas C, Haake F
Phys Rev Lett . 2002 Aug; 89(8):083902. PMID: 12190465
Feshbach's projector technique is employed to quantize the electromagnetic field in optical resonators with an arbitrary number of escape channels. We find spectrally overlapping resonator modes coupled due to the...
