Partially coherent Double-vortex beams Turbulent atmosphere
2013/7/3
Based on the extended Huygens–Fresnel principle, we study the propagation properties of partially coherent double-vortex beams in turbulent atmosphere. The intensity distribution of the beams on propa...
Prospects of coherent control in turbid media: Bounds on focusing broadband laser pulses
Prospects coherent control turbid media broadband laser pulses
2011/8/11
Abstract: We study the prospects of controlling transmission of broadband and bi-chromatic laser pulses through turbid samples. The ability to focus transmitted broadband light is limited via both the...

Low-threshold plasmon
2011/9/2
We theoretically propose directional, low-threshold plasmon lasing in both the near-infrared and visible wavelengths by utilizing spatially coherent surface plasmon polaritons on a meta-surface.The ga...
In understanding the physical, chemical and biological properties of a molecule by obtaining detailed information about its structure, there is an ultimate wish: the visualization of this very molecul...
Cross-Kerr nonlinearity between continuous-mode coherent states and single photons
Cross-Kerr nonlinearity continuous-mode coherent states single photons
2013/7/3
Weak cross-Kerr nonlinearities between single photons and coherent states are the basis for many applications in quantum-information processing. These nonlinearities have so far mainly been discussed ...

2013/7/3
We experimentally study the generation of a partially coherent non-diffractive beam by focusing a partially coherent vortex beam with an axicon. The investigation results show that when the partially ...
We construct a class of coherent spin-network states that capture proprieties of curved space-times of the Friedmann-Lamaˆıtre-Robertson-Walker type on which they are peaked.
