N2 - Recent theoretical and experimental studies show that the Lebed "magic angle" effects (for magnetic field rotations in the least conducting, y-z, plane of quasi-one-dimensional conductors) can be greatly enhanced by the presence of a field along the most conducting, x, direction. Here, we complete the picture with numerical Boltzmann calculations including the Nernst effect Szx. Our results confirm that Bx enhances the σzz peaks at magic angles, but does not qualitatively affect the angular dependence of the Nernst effect Szx. These results suggest that the magic angle effect cannot be explained simply by the Boltzmann transport of quasiparticles on the Fermi surface.
