Long-range Order and Directional Defect Propagation in the Nonreciprocal XY Model with Vision Cone Interactions

Sarah A. M. Loos, Sabine H. L. Klapp, Thomas Martynec

We study a two-dimensional, nonreciprocal XY model, where each spin interacts only with its nearest neighbours in a certain angle around its current orientation, i.e., its `vision…
