27 Nov 2014 | Abstract: | We study the ground state quantum fragmentation in a mixture of a polar
condensate and a ferromagnetic condensate when subject to an external magnetic
field. We pay more attentions to the polar condensate and find that it will be
less fragile in the mixture when perturbed by the magnetic field. Both atom
numbers and the number fluctuations in the spin-0 component will keep in a high
magnitude of order of $N$ when the magnetization of the system is increased.
The role of the ferromagnetic condensate is to provide a uniform and stable
background which can delay the rapid shrink of the 0-component population and
make it possible to capture the extquotedblleft super-fragmentation
extquotedblright. Our method has potential applications in measuring the
inter-species spin-coupling interaction through adjusting the magnetic field. | Source: | arXiv, 1411.7633 | Services: | Forum | Review | PDF | Favorites |
