The realization of global symmetries can depend on the geometry of theunderlying space. In particular, compactification can lead to spontaneousbreaking of such symmetries. Four-dimensional QCD with fundamentalrepresentation fermions embedded in a space with one compact spatial dimensionhas a critical length, at which the theory undergoes a phase transition anddevelops a ground state that is no longer charge conjugation invariant. We showthis behavior with simulations of three color, four flavor QCD. We use unrootedstaggered fermion at two values of the lattice spacing and several quarkmasses. We discuss the dependence of the transition on the dynamical fermionmass as well as its connection to the finite temperature and chiral phasetransitions.Comment: 13 pages, 9 figures, JHEP styl
