I will discuss holographic models of striped phases, which offer a theoretical laboratory to probe the unconventional behavior of many strongly interacting quantum systems. In particular, I will focus on the structure of the Fermi surface and how it is affected by the breaking of translational invariance. As we will see, the Fermi surface is very sensitive to lattice effects, and starts to dissolve when the lattice is sufficiently strong, leaving behind disconnected segments reminiscent of Fermi arcs. This effect appears to be a generic consequence of strong inhomogeneities, independently of whether translational invariance is broken spontaneously or explicitly.
