Laser tracking and pointing at a simulated moving target in atmosphere 1.27km away is realized experimentally,in which stimulated Brillouin scattering (SBS) pha
We take the viewpoint that X(1576) is the tetraquark state which consists of a scalar diquark and an antiscalar-diquark in relative P-wave, and calculate its ma
The dynamic behaviour of a modulated torsion pendulum used to test the weak equivalence principle (WEP) is studied in detail. Theoretical analysis shows that th
We perform ab initio calculations on the self-assembled base-functionalized single-walled carbon nanotubes (SWNTs) which exhibit the quasi-1D ‘ladder’ structu
We consider the quantum superposition of two coherent states shifted in phase by 3π/2 , |α> and|- iα>, as well as special states that are characterized solely
