Abstract: | This paper investigates the squeezing properties of an atom laser
without rotating-wave approximation in the system of a binomial states
field interacting with a two-level atomic Bose--Einstein condensate.
It discusses the influences of atomic eigenfrequency, the interaction
intensity between the optical field and atoms,parameter of the binomial
states field and virtual photon field on the squeezing properties.
The results show that two quadrature components of an atom laser can be
squeezed periodically. The duration and the degree of squeezing an atom
laser have something to do with the atomic eigenfrequency and the parameter
of the binomial states field, respectively. The collapse and revival
frequency of atom laser fluctuation depends on the interaction intensity
between the optical field and atoms. The effect of the virtual photon field
deepens the depth of squeezing an atom laser. |
