Stripe Order

Within a strong-coupling perturbative approach, based on a Cumulant Expansion of the extended single-band Hubbard model, we analyze the low-energy behavior of the chargevertex function. It is shown that quantum critical charge fluctuations drive the system towards a stripe-phase characterized by a finite wave-vector that yields information on the stripe order. Some relevant features observed in ARPES experiments on Bi2212 and LSCO are qualitatively reproduced.
