which is considerably less than the free field value c = 1 / 2. The scaling function b has the limiting values lim$_{T/µ}$$_{→}$$_{0}$ − b = 0, and lim$_{T/µ}$$_{→−∞}$ b = ∞ . 

Since the pressure is proportional to c , the same density occurs at two different pressures. One sees that for µ/T < − 0 . 56, the density increases with pressure as it should. For µ/T > − 0 . 56 the density decreases with increasing pressure, violating dp/dV < 0, and should thus be viewed as an unphysical region. We interpret this as a phase transition occuring at z$_{c}$ = e − 0 . 56 = 0 . 57, where the critical density

At this critical point c ( − 0 . 56) = 0 . 24. This perhaps corresponds to a transition to a crystaline phase. We cannot prove this, since we have not calculated the shear
