Fluctuating stripes in the Hubbard model

The normal state of high-T_c superconductors is characterized by various competing orders, among which charge and spin stripes are the most commonly observed and studied. The nature of stripe order and its possible interplay with superconductivity could be essential to understanding the physics of high-T_c cuprates. In this talk, we will present studies of charge and spin stripes in the Hubbard model, which is a canonical model for studying cuprates and have shown many essential features of the cuprate phase diagram. We discuss findings from exact numerical simulations of the model at finite temperatures, the alignment of the results with exact ground state simulations and experimental observations, as well as the implications for understanding the normal state from which superconductivity emerges.
