<正> We propose a scheme to generate atomic cluster states of arbitrary configuration in the cavity quantumelectrodynamics (QED) system.The process is achieved
<正>The open electron resonator is a mesoscopic device that has attracted considerable attention due to its remarkable behavior:conductance oscillations.In this
<正> Two-mode circular states,which are superposition states from some two-mode coherent states,are studiedtheoretically.It is shown that under certain conditio
