摘要
We present theoretical prospects for creating p-wave paired BCS states of magnetic trapped fermionic atoms. Based on our earlier proposal of using de electric fields to control both the strength and anisotropic characteristic of an atom-atom interaction and our recently completed multichannel atomic collision calculations we discover that p-wave pairing with K-40 and Rb-82,Rb-84,Rb-86 in the low field seeking maximum spin-polarized state represents excellent choices for achieving superfluid BCS states and may be realizable with current technology in laser cooling, magnetic trapping, and evaporative/sympathetic cooling, provided the required strong electric field can be applied. We also comment on the prospects of similar p-wave paired BCS states in Li-6, and more generally on creating other types of exotic BCS states. Our study will open a new area in the vigorous pursuit to create a quantum degenerate fermionic atom vapor. [S1050-2947(99)02509-3].
