If the situation of quantum gravity nowadays is nearly the same as that of quantum mechanics in its early time of Bohr and Sommerfeld, then a first-step study o
Considering that KBe2BOsF2 (KBBF) is an outstanding deep ultraviolet crystal which can generate the shortest wavelengths in second harmonic generation and sum-f
The percolation clusters with varying occupy probability are constructed. Invasion percolation (IP) in percolation cluster is investigated by means of IP algori
Based on the principle of the graded-index multimode interference (MMI), an 8 × 8 MMI optical coupler is designed and fabricated by using K+-Na+ ion-exchange
The atomic, binding and electronic structures of very thin Zr chains are studied by the first-principles densityfunctional method. The present calculations reve
The polarization dependence of electric field for hemicyanine layers deposited by the Langmuir-Blodgett (LB)technique has been measured. The experimental result
