Fluctuating stripe order in the single-band Hubbard model for cuprates

ORAL

Abstract

A description of the physics associated with the cuprates must account for the translational and rotational symmetry breaking, in the form of stripes, observed in the wide array of compounds as a function of doping. We investigate the emergence of stripes in the single-band Hubbard model using determinant quantum Monte Carlo (DQMC) simulations at finite temperatures and density matrix renormalization group (DMRG) ground state calculations. Tuning the doping and model parameters, we observe and characterize the evolution of fluctuating stripes at high temperatures throughout the phase diagram, and our results demonstrate the importance of longer-range kinetic terms in fine tuning the spin incommensurability and stripe filling.
