要旨

We propose a mechanism to change the interaction strengths of a two-component condensate. It is shown that the application of π/2 pulses allows us to alter the effective interspecies-interaction strength as well as the effective interaction strength between particles of the same kind. This mechanism provides a simple method to transform spatially stable condensates into unstable ones and vice versa. It also provides a means to store a squeezed spin state by turning off the interaction for the internal states and thus allows to gain control over many-body entangled states. ©2002 The American Physical Society
