We propose a most simple and experimentally feasible scheme for teleporting unknown atomic entangled states in driven cavity quantum electrodynamics (QED). In o

We develop a microscopic theory of the nematic phase with consideration of the effect of the collective excitation on properties of nematic liquid crystals. The

A new representation of an arbitrary and unknown N-particle state is presented at first. As an application,a scheme for teleporting an arbitrary and unknown N-p
A single particle magneto-confined in a one-dimensional (1D) quantum wire experiences a harmonic potential,and imposing a sharply focused laser beam on an appro
In this paper, chaos in a voltage-mode controlled buck converter is studied. The existence of chaos is proven theoretically in this system. The proof consists o
In the q(q) quark model, the states π(1300), η(1295) and η(1475) are assigned as the 21S0 meson nonet. The mass of the isodoublet remains interesting and nee
A novel active backstepping control method is presented for synchronizing two identical Rossler hyperchaotic systems with each other, and extended to achieve th

Time-resolved measurement of atomic emission enhancement is performed by using a 500-fs KrF laser pulse incident upon a high density supersonic O2 gas jet, sync
