Enhanced detectability of axion's electromagnetic response with a RF-excited magnetic field in cavity
Li Gao, Hao Zheng, Xianing Feng +4
Haloscope is one of the typical installations to detect the electromagnetic responses (EMRs) of axion field in radio-frequency (RF) and microwave bands. Given that the detectable s…
Klein-tunneling-enhanced directional coupler for Dirac electron wave in graphene
L. Zhao, Wenhui Duan
Using the coupled-mode theory in guided-wave optics and electronics, we explore a directional coupling structure composed of two parallel waveguides electrostatically induced by th…
Electromagnetically induced spatial light modulation
L. Zhao, T. Wang, S. F. Yelin
We theoretically report that, utilizing electromagnetically induced transparency (EIT), the transverse spatial properties of weak probe fields can be fast modulated by using optica…
Coherent Graphene Devices: Movable Mirrors, Buffers and Memories
L. Zhao, S. F. Yelin
We theoretically report that, at a sharp electrostatic step potential in graphene, massless Dirac fermions can obtain Goos-Hänchen-like shifts under total internal reflection. Base…
Image Storage in Hot Vapors
L. Zhao, T. Wang, Y. Xiao +1
We theoretically investigate image propagation and storage in hot atomic vapor. A system is adopted for imaging and an atomic vapor cell is placed over the transform plane. Th…
Diffusion induced decoherence of stored optical vortices
T. Wang, L. Zhao, L. Jiang +1
We study the coherence properties of optical vortices stored in atomic ensembles. In the presence of thermal diffusion, the topological nature of stored optical vortices is found n…
