摘要
A quantum interference mechanism of the stripe phase instability in quasi one-dimensional (1D) repulsive electron system is proposed. The leading spin-charge coupling term in Landau functional is derived microscopically. It is shown that away from half filling, periodic lattice potential causes cooperative condensation of the spin and charge superlattices, which constitute a 1D analogue of the experimentally observed quasi 2D structures in lanthanum cuprates and nickelates. Renormalization group analysis qualitatively supports the Hartree-Fock picture.
