We construct a new type of expanders, from measure-preserving affine actions with spectral gap on origami surfaces, in each genus g > 0. These actions are the first examples of actions with spectral gap on surfaces of genus g > 1. We prove that the new expanders are coarsely distinct from the classical expanders obtained via the Laplacian as Cayley graphs of finite quotients of a group. In genus g = 1, this implies that the Margulis expander, and hence the Gabber-Galil expander, is coarsely distinct from the Selberg expander. This is joint work with Goulnara Arzhantseva, Dawid Kielak and Damian Sawicki.
