Combining five dimensional domain wall fermions in Euclidian space with gauge fields that undergo gradient flow in the fifth dimension can can lead to a gauge theory of interacting chiral fermions on one boundary, and "fluff" on the other: mirror fermions which do not interact with gauge fields except through their topology. I describe how this works and attempts to formulate the effective four dimensional lattice theory of the surface modes. Can this serve as a nonperturbative regulator for chiral gauge theories?

Gauge theories are fundamental to our understanding of interactions between the elementary constituents of matter as mediated by gauge bosons. However, computing the real-time dynamics in gauge theories is a notorious challenge for classical computational methods. In the spirit of Feynman's vision of a quantum simulator, this has recently stimulated theoretical effort to devise schemes for simulating such theories on engineered quantum-mechanical devices, with the difficulty that gauge invariance and the associated local conservation laws (Gauss laws) need to be implemented.
