An overview is given of our present understanding of superconductivity with
spontaneously broken translation symmetry in polarized Fermi systems. The
existence of "crystalline" superconducting phases is considered in a wide range
of systems, prominent examples being conduction electrons in metals, ultra-cold
atoms in a trap, nuclear matter, and dense quark systems. The underlying physics
is delineated and theoretical approaches to the inhomogeneous phases and their
properties are discussed. From the experimental side it is argued that supercon-
ductivity with imbalance-induced order parameters is realized in layered organic
