According to density matrix equations of the interaction between light and matter,the expression for the susceptibility of the Eu~(3+):Y_2SiO_5 crystal is obtai
We investigate the conductance and shot noise properties of quasi-particle transport through a superconducting barrier in graphene.Based on the Blonder,Tinkham,
We propose a new method to control the directed quantum transport of ultracold atoms in a one-dimensional optical lattice.In this proposal,the effective tunneli
A single sheet of graphene exhibits the ability to turn polarization of light by several degrees in modest magnetic fields.Here we demonstrate that giant angle
“Giant” Cd Se/Cd S core/shell nanocrystals(NCs) were synthesized with thick Cd S shell(15 monolayers), and the x-ray diffraction(XRD) measurement indicates th
