18. For a Li 6 - Li 7 mixture with Bose-Fermi scattering length of 0.25 nm in a lattice of depth 15 recoil energies and interwell distance d = 425 nm, one finds t10 nK. [T.-L. Ho and Q. Zhou, Phys. Rev. Lett. PRLTAO 0031-9007 10.1103/PhysRevLett.99.120404 99, 120404 (2007)].
19. Beyond-mean-field corrections should be taken into account in the thermodynamic limit where phase fluctuations with vanishing wave vectors are known to destroy long-range order, but finite systems have a natural infrared cutoff, which blocks this effect.

29. We considered lattice sizes up to ~ 50 × 50 without observing qualitative changes. Our findings are also independent from the vortex amplitude ansatz f i.
