  On a compact space with non-trivial cycles, for sufficiently small values of
the radii of the compact dimensions, SU(N) gauge theories coupled with fermions
in the fundamental representation spontaneously break charge conjugation, time
reversal and parity. We show at one loop in perturbation theory that physical
signature for this phenomenon is a non-zero baryonic current wrapping around
the compact directions. The persistence of this current beyond the perturbative
regime is checked by lattice simulations.
