Helical ordering in spin-one color superconductors

Full text: We analyze spin-one color superconductivity of a single-flavor quark matter using the Ginzburg-Landau theory. By explicit minimization of the free energy we demonstrate that in a part of the parameter space the system exhibits a non-inert equilibrium state, different from states considered so far in literature. Finally we show that tiny weak-interaction effects induce a small parity-violating term in the Ginzburg-Landau functional, which causes the system to develop a long-range helical ordering in the ground state.
