Meandering stripes in the frustrated $J_{1}$ - $J_{2}$ Ising model on the honeycomb lattice

Denis Gessert, Martin Weigel, Wolfhard Janke

We study the frustrated $J_{1}$ - $J_{2}$ Ising model on the honeycomb lattice with ferromagnetic nearest-neighbor couplings fixed at $J_{1} = 1$ and strong antiferromagnetic next-nearest-ne…

Frustrated Ising model on the honeycomb lattice: Metastability and universality

Denis Gessert, Martin Weigel, Wolfhard Janke

We study the Ising model with competing ferromagnetic nearest- and antiferromagnetic next-nearest-neighbor interactions of strengths $J_{1} > 0$ and $J_{2} < 0$ , respectively, on the h…

Partition function zeros of the frustrated $J_{1}$ - $J_{2}$ Ising model on the honeycomb lattice

Denis Gessert, Martin Weigel, Wolfhard Janke

We study the zeros of the partition function in the complex temperature plane (Fisher zeros) and in the complex external field plane (Lee-Yang zeros) of a frustrated Ising model wi…
