磁场中费米原子的破缺超流性
Breached superfluidity of fermionic atoms in magnetic field
摘要：
在费什巴赫共振实验中，我们导出了费米子原子在外加磁场中破裂配对超流相的能隙，它是由磁场对费什巴赫共振的失谐量决定的。我们证明了BCS超流态只存在于磁场失谐量小于1的临界磁场失谐量时，而这个临界磁场失谐量是由磁场失谐量对能隙$ Δ_0 $的塞曼能裂相等决定的.
英文摘要：
We derived the energy gap of a breached pairing superfluidity phase of fermionic atoms in an external magnetic field in Feshbach resonance experiments which is determined by the magnetic - field detuning from the Feshbach resonance. We show that a BCS superfluid state exists only for the magnetic - field detuning smaller than one critical, and this critical magnetic - field detuning is determined by the equality of the Zeeman energy splitting for the magnetic - field detuning to the energy gap $ Δ_0 $.
