Optical dipole force on ladder-like three-level atomic systems driven by chirped few-cycle-pulse laser fields
Optical dipole force ladder-like three-level atomic systems chirped few-cycle-pulse laser fields Optics
2012/5/17
We report a study on the optical dipole force in a ladder like three level atomic systems in the context of coherent population transfer with the chirped few-cycle-pulse laser fields. The phenomenon o...
The analogy between optical beam shifts and quantum weak measurements
analogy between optical beam shifts quantum weak measurements Optics
2012/4/19
We describe how the notion of optical beam shifts (including the spatial and angular Goos-H\"anchen shift and Imbert-Federov shift) can be understood as a classical analogue of a quantum measurement o...
Breakdown of the photon lifetime concept in optical cavities with negative group delay
the photon lifetime optical cavities negative group delay
2011/8/18
Abstract: The concept of photon lifetime in a cavity is shown to be non-relevant in the case where the cavity round-trip group delay is negative due to the presence of a strong intracavity negative di...

Attojoule all-optical single quantum dot Quantum Physics
2011/8/17
Abstract: We experimentally investigate the dynamic nonlinear response of a single quantum dot (QD) strongly coupled to a photonic crystal cavity-waveguide structure. The temporal response is measured...

Effects of Fermi-surface optical sum rule in pnictides
2010/11/25
In this paper we investigate the effects of the band shifts induced by the interband spin-fluctuation coupling on the optical sum rule in pnictides. We show that, despite the shrinking of the Fermi su...
Currently proposed architectures for long-distance quantum communication rely on networks of quantum processors connected by optical communications channels [1,2]. The key resource for such networks ...

Repulsively-bound exciton-biexciton states optical lattices
2010/11/17
We show that the interplay between spin-changing collisions and quadratic Zeeman coupling
provides a novel mechanism for the formation of repulsively bound composites in high-spin fermions,which we i...
Despite weak spin-orbit coupling and an indirect band gap, significant optical spin orientation
is possible in silicon. We show this by performing full band-structure calculations of the phonon-assis...
