Query: Breached pair superfluidity: a brief review   Interior gap superfluidity was introduced together with Frank Wilczek. Later
on together with our collaborators, we generalized this new possibility of
superfluidity to a broader concept, breach pair superfluidity. In the occasion
to celebrate Professor Frank Wilczek's seventieth birthday and his productive
career in several major areas in physics, I dedicate this note to recall the
exciting times of developing this idea, the main aspects of the proposed phase,
and the discussion on its stability condition.
