Control excitation and coherent transfer in a dimer
Hong-rong Li, Pei Zhang, Yingjun Liu +2
In this article, the processes of energy absorption and coherent transfer in a dimer is studied. The dimer includes two two-level pigments --- donor and acceptor, where donor is as…
Super sub-wavelength patterns in photon coincidence detection
Ruifeng Liu, Pei Zhang, Yu Zhou +2
High-precision measurements implemented by means of light is desired in all fields of science. However, light is a wave and Rayleigh criterion gives us a diffraction limitation in…
Evaluating Laguerre-Gaussian beams with an invariant parameter
Junling Long, Ruifeng Liu, Yunlong Wang +4
We define a new parameter about Laguerre-Gaussian (LG) beams, named , which is only related to mode indices and . This parameter is able to both evaluate and dist…
Characterizing vortex beam with angular-double-slit interference
Ruifeng Liu, Junling Long, Feiran Wang +4
The Fraunhofer diffraction intensity distribution of Laguerre-Gaussian beam is studied in an angular-double-slit interferometer. We demonstrate that the spiral phase structure of v…
