Magnetoabsorption spectra of magnetoexciton transitions in GaAs/Ga0.7Al0.3As quantum wells

The internal transitions and absorption spectra of confined magnetoexcitons in GaAs/Ga0.TA10.aAs quan- tum wells have been theoretically investigated under magnetic fields along the growth direction of the semiconductor heterostructure. The magnetoexciton states are obtained within the effective-mass ap- proximation by using a variational procedure. The trial exciton-envelope wavefunctions are described as hydrogeniclike polynomial functions. The internal transition energies are investigated by studying the allowed magnetoexcitonic transitions using terahertz radiation circularly polarized in the plane of the quantum well. The intraexcitonic magnetoabsorption to 2p^± like magnetoexciton states as functions of the coefficients are obtained for transitions from 1s-like applied magnetic field.     

Drop Size Dependence of the Contact Angle of Nanodroplets

The contact angle of nanosized non-polarized argon sessile droplets on a solid substrate is studied by using molecular dynamics simulations. It is found that the drop size dependence of the contact angle is sensitive to the interaction between the liquid molecules and solid molecules. The contact angle decreases with the decreasing drop size for larger interaction between the liquid molecules and the solid substrate, and vice versa. This observation is consistent with most of the previous theoretical and experimental results.

九十年代是宇宙学的黄金时代

 暂时我们还只有一些不完备的规律,这些规律制约着宇宙在所有非极端情形下的行为.现在看来这些规律都只是某个有待我们发现的统一理论的一部分.我们正在不断地取得进展,可能到本世纪末我们就能找到这个理论.
