Critical Behavior of a Three-State Potts Model on a Voronoi Lattice

We use the single-histogram technique to study the critical behavior of the three-state Potts model on a (random) Voronoi-Delaunay lattice with size ranging from 250 to 8000 sites. We consider the effect of an exponential decay of the interactions with the distance,$J(r)=J_0\exp(-ar)$, with $a>0$, and observe that this system seems to have critical exponents $\gamma$ and $\nu$ which are different from the respective exponents of the three-state Potts model on a regular square lattice. However, the ratio $\gamma/\nu$ remains essentially the same. We find numerical evidences (although not conclusive, due to the small range of system size) that the specific heat on this random system behaves as a power-law for $a=0$ and as a logarithmic divergence for $a=0.5$ and $a=1.0$Comment: 3 pages, 5 figure

The Reverse-Entanglement Principle: Why Religious Arbitration of Federal Rights Is Unconstitutional

Imagine you apply to be a cashier at a supermarket. At the beginning of the interview, you sign an employment application. You don’t get the job, and your interviewer’s remarks make you suspect it’s because you are Muslim. You sue in federal court under Title VII of the Civil Rights Act of 1964. The supermarket moves to dismiss the suit because your employment application included an agreement to arbitrate all Title VII disputes. The court dismisses your case and compels arbitration
