Convex Optimization over Classes of Multiparticle Entanglement

Author(s): Jiangwei Shang and Otfried Gühne

A well-known strategy to characterize multiparticle entanglement utilizes the notion of stochastic local operations and classical communication (SLOCC), but characterizing the resulting entanglement classes is difficult. Given a multiparticle quantum state, we first show that Gilbert’s algorithm can...

Tunable optical nonreciprocity and a phonon-photon router in an optomechanical system with coupled mechanical and optical modes

Author(s): Guolong Li, Xiao Xiao, Yong Li, and Xiaoguang Wang

We propose a multimode optomechanical system to realize tunable optical nonreciprocity that has the prospect of making an optical diode for information technology. The proposed model consists of two subsystems, each of which contains two optical cavities, injected with a classical field and a quantu...

Rayleigh scattering of twisted light by hydrogenlike ions

Author(s): A. A. Peshkov, A. V. Volotka, A. Surzhykov, and S. Fritzsche

The elastic Rayleigh scattering of twisted light and, in particular, the polarization (transfer) of the scattered photons have been analyzed within the framework of second-order perturbation theory and Dirac's relativistic equation. Special attention was paid hereby to the scattering on three differ...

Synopsis: A Way to Cool Dark Matter

APS Physics - Thu, 2018-02-01 12:00

A new model introduces a charge for dark matter, which would allow it to radiate energy and form compact objects such as dark stars or dark galaxies.
