Normal LOFF weak coupling strong coupling BCS
Tricritical point General study by Combescot and Mora (2002). Favored structure2 antipodal vectors • At T = 0 the antipodal vector leads to a second order phase transition. Another tricritical point ? (Matsuo et al. 1998) • Change of crystalline structure from tricritical to zero temperature?
Two-dimensional case (Shimahara 1998) Analysis close to the critical line
Weak equilibrium: Electrical neutrality:
Rotation and translation by compensate locally atP
