✦ Synopsis

We report on detailed Hartree-Fock calculations of the unidirectional charge density wave orientation energy induced by a tilted magnetic ÿeld. We ÿnd that for current experimental samples stripes are oriented perpendicular to the in-plane ÿeld, consistent with experiment. For wider two-dimensional electron systems we predict tilt-induced stripe states with variable anisotropy energy sign.
