Amperean Pairing Instability in the U(1) Spin Liquid State with Fermi Surface and Application to
Recent experiments on the organic compound
raise the possibility that the system may be described as a quantum spin
liquid. Here we propose a pairing state caused by the `Amperean' attractive
interaction between spinons on a Fermi surface mediated by the U(1) gauge
field. We show that this state can explain many of the observed low temperature
phenomena and discuss testable consequences.Comment: 4+ pages, 1 fi
