Non-Hermitian Hamiltonians are widely used in describing open systems with gain and loss,among which a key phenomenon is the non-Hermitian skin effect.Here we report an experimental scheme to realize a twodimensional(...
Single-layer superconductors[1]have been the subject of considerable interests as they are ideal systems for the fundamental understanding of two-dimensional(2D)physics and for device applications.A few singlelayer su...

We propose an ultracompact triplexer based on a shift of the cutoff frequency of the fundamental mode in a planar photonie crystal waveguide (PCW) with a triangular lattice of air holes. The shift is realized by mod...
A proposal for photonic generation of a microwave signal is presented by employing a dual wavelength erbiumdoped fibre ring laser. In the laser, a microring resonator is cascaded with a tunable bandpass filter to serv...

We propose a scheme for the reconstruction of a cavity field state.In the scheme the cavity field is first displaced by a microwave source,and then couples with a three-level A-type atom in a Raman manner.After an app...

We propose a scheme for teleporting a three-particle entangled Greenberger-Horne-Zeilinger state to three distant users.The scheme operates essentially through the sharing of Einstein-Podolsky-Rosen pairs followed by ...

A new prototype atomic fountain clock working in the micro-gravity environment is proposed.The successive Ramsey interactions of cold atoms and oscillatory field are realized by means of comp u ter-con trolled periodi...
