Partially filled stripes in the two dimensional Hubbard model: statics and dynamics

Abstract

The internal structure of stripes in the two dimensional Hubbard model is studied by going beyond the Hartree-Fock approximation. Partially filled stripes, consistent with experimental observations, are stabilized by quantum fluctuations, included through the Configuration Interaction method. Hopping of short regions of the stripes in the transverse direction is comparable to the bare hopping element. The integrated value of $n_{\vec{\mathbf{k}}}$ compares well with experimental results.
