Terahertz heterodyne receivers with high sensitivity and spectral resolution are crucial for various applications.Here,we present a room-temperature atomic terahertz heterodyne receiver that achieves ultrahigh sensiti...
We examine the effects of local turbulence Reynolds number Rλ and inflow conditions on the magnitude of vorticity in plane turbulent wakes. Measurements of the spanwise component (ω3) of the fluctuating vorticity ...

The signature of the self-microlensing in compact binaries(white dwarfs,neutron stars and black holes)is a flare with the characteristic time of typically a few minutes.The probability of detecting these microlensing ...
In the previous paper(Chin.Phys.lett.6(1989)233)the-amplification,luminosity distances and probabilities for lensing an the case of small optical depth were discussed.As the second part of this work,the present paper ...
The attenuation coefficient of the impressed first sound due to the scattering of random background of the second sound is calculated.The result shows that this is an important factor which gives rise the attenuation ...
