The $N$-clock model: Variational analysis for fast and slow divergence rates of $N$

no code implementations17 Dec 2020 Marco Cicalese, Gianluca Orlando, Matthias Ruf

We find a fast rate of divergence of $N$ with respect to the lattice spacing for which the $N$-clock model has the same discrete-to-continuum variational limit of the $XY$ model, in particular concentrating energy on topological defects of dimension 0.
