摘要：

We study the properties of wave-packet states with vortex structure. In particular we present the characteristics of a two-mode radiation field characterized by a configuration-space wave function psi(v)=(x-iy)(m)e(-(x2+y2)/2 sigma 2). We show the generation of such states by the interaction of Lambda systems with squeezed radiation in a two-mode cavity. The two modes are correlated due to entanglement, which also produces the mixed stare of each mode even though the state of the two-mode field is a pure state. [S1050-2947(97)04011-0].
