Comment on “Nature of Long-Range Order in Stripe-Forming Systems with Long-Range Repulsive Interactions”

Figure 1

Caloric curves $\beta (E)$ vs energy per spin $E/N$. (a) dipolar Ising model for $\delta =2$, where a nematic phase is observed [5]. Horizontal lines denote transition temperatures obtained by Maxwell’s construction. From left to right: configurations in the striped, nematic, and isotropic phases, respectively. (b) $XY$ model for $J=1$ at the KT transition.
