On Quartet Superfluidity of Fermionic Atomic Gas
Abstract
The possibility of a quartet superfluidity in fermionic systems is studied as a new aspect of atomic gas at ultralow temperatures. The fourfold degeneracy of a hyperfine state and moderate coupling is indispensable for the quartet superfluidity to occur. Possible superconductivity with quartet condensation in electron systems is discussed.
