Figure 1

(Color online) Zero temperature phase diagram of two dimensional stripe ordering model in plane of doping $\delta$ and tetragonal symmetry breaking parameter $S$. Solid lines: phase transition between paramagnetic metal (“disordered”) and density wave (“stripe”) state. Star (light blue online): tricritical point separating first-order (heavy line) and second-order (light line) phase transitions. Dashed line (black online); putative second-order density wave transition preempted by first-order transition. Small filled circles (red online): paramagnetic nematic phase, defined only at $S=0$ and separated from density wave and disordered phases by second-order phase transition points marked, respectively, by large circle (green online) and square (purple online). Nematic phase and associated transitions are also preempted by first-order transitionReuse & Permissions

Figure 2

(Color online) Dependence on control parameter $\delta$ of inverse correlation length parameters for $x$ (solid line) and $y$ (dashed line) wave vectors for different levels of explicit symmetry breaking ${\delta }_x={\delta }_y+\Delta$ with anisotropy parameters $\Delta$ as indicated and interactions $\overline{u}=0.3$ and $\overline{v}=0.6$.Reuse & Permissions
