Motivated by Rb85-Rb87 mixture I will discuss the thermodynamics of
a degenerate gas of two species of bosonic atoms interacting through
a p-wave Feshbach resonance. I will show that it exhibits a finite-momentum
atomic-molecular superfluid (AMSF) phase, sandwiched by a molecular p-wave
(orbital spinor) superfluid and by an s-wave atomic superfluid at large
negative and positive detunings, respectively. The magnetic field can be used
to tune the modulation wavevector of the AMSF state, as well as to drive quantum
phase transitions in this rich system.
