Query: Phase diagram of dilute nuclear matter: Unconventional pairing and the
  BCS-BEC crossover   We report on a comprehensive study of the phase structure of cold, dilute
nuclear matter featuring a SD condensate at non-zero isospin asymmetry, within
wide ranges of temperatures and densities. We find a rich phase diagram
comprising three superfluid phases, namely a Larkin-Ovchinnikov-Fulde-Ferrell
phase, the ordinary BCS phase, and a heterogeneous, phase-separated BCS phase,
with associated crossovers from the latter two phases to a homogeneous or
phase-separated Bose-Einstein condensate of deuterons. The phase diagram
contains two tricritical points (one a Lifshitz point), which may degenerate
into a single tetracritical point for some degree of isospin asymmetry.
