Robust entanglement between a movable mirror and atomic ensemble and entanglement transfer in coupled optomechanical system.

Scientific reports

Bai CH, Wang DY, Wang HF, Zhu AD, Zhang S.
PMID: 27624534
Sci Rep. 2016 Sep 14;6:33404. doi: 10.1038/srep33404.

We propose a scheme for the creation of robust entanglement between a movable mirror and atomic ensemble at the macroscopic level in coupled optomechanical system. We numerically simulate the degree of entanglement of the bipartite macroscopic entanglement and show...

Coupling and Stacking Order of ReS2 Atomic Layers Revealed by Ultralow-Frequency Raman Spectroscopy.

Nano letters

He R, Yan JA, Yin Z, Ye Z, Ye G, Cheng J, Li J, Lui CH.

Nano Lett. 2016 Feb 10;16(2):1404-9. doi: 10.1021/acs.nanolett.5b04925. Epub 2016 Jan 14.

We investigate the ultralow-frequency Raman response of atomically thin ReS2, a special type of two-dimensional (2D) semiconductors with unique distorted 1T structure. Bilayer and few-layer ReS2 exhibit rich Raman spectra at frequencies below 50 cm(-1), where a panoply of...

Capturing relativistic wakefield structures in plasmas using ultrashort high-energy electrons as a probe.

Scientific reports

Sci Rep. 2016 Jul 11;6:29485. doi: 10.1038/srep29485.

A new method capable of capturing coherent electric field structures propagating at nearly the speed of light in plasma with a time resolution as small as a few femtoseconds is proposed. This method uses a few femtoseconds long relativistic...

Classical-to-quantum transition behavior between two oscillators separated in space under the action of optomechanical interaction.

Scientific reports

Bai CH, Wang DY, Wang HF, Zhu AD, Zhang S.
PMID: 28566715
Sci Rep. 2017 May 31;7(1):2545. doi: 10.1038/s41598-017-02779-w.

We propose a scheme to show that the system consisting of two macroscopic oscillators separated in space which are coupled through Coulomb interaction displays the classical-to-quantum transition behavior under the action of optomechanical coupling interaction. Once the optomechanical coupling...

In order for fuel cells to have commercial viability as alternative fuel sources, researchers need to develop highly active and robust fuel cell electrocatalysts. In recent years, the focus has been on the design and synthesis of novel catalytic...

Semiconducting-to-metallic photoconductivity crossover and temperature-dependent Drude weight in graphene.

Physical review letters

Frenzel AJ, Lui CH, Shin YC, Kong J, Gedik N.
PMID: 25126929
Phys Rev Lett. 2014 Aug 01;113(5):056602. doi: 10.1103/PhysRevLett.113.056602. Epub 2014 Jul 31.

We investigate the transient photoconductivity of graphene at various gate-tuned carrier densities by optical-pump terahertz-probe spectroscopy. We demonstrate that graphene exhibits semiconducting positive photoconductivity near zero carrier density, which crosses over to metallic negative photoconductivity at high carrier density....
