The repulsive Hubbard model has been immensely useful in understanding strongly
correlated electron systems and serves as the paradigmatic model of the field. Despite its …

The fermionic Hubbard model (FHM) describes a wide range of physical phenomena
resulting from strong electron–electron correlations, including conjectured mechanisms for …

Unidirectional (“stripe”) charge density wave order has now been established as a
ubiquitous feature in the phase diagram of the cuprate high-temperature superconductors …

The sign problem is the fundamental limitation to quantum Monte Carlo simulations of the
statistical mechanics of interacting fermions. Determinant quantum Monte Carlo (DQMC) is …

We study the square-lattice extended Hubbard model with on-site U and nearest-neighbor V
interactions by exact diagonalization. We show that nonequilibrium quench dynamics can …

Understanding the relationship between stripe order and other phenomena, including
antiferromagnetism and superconductivity, is one of the central issues in cuprate …

We use cellular dynamical mean-field theory with extended unit cells to study the ground
state of the two-dimensional repulsive Hubbard model at finite doping. We calculate the …

Motivated by the recent discovery of anomalously strong nearest-neighbor attraction in the
one-dimensional hole-doped cuprate Ba 2+ x Sr x CuO 3+ δ, we investigate the d-wave …

We explore the effect of inhomogeneity on electronic properties of the two-dimensional
Hubbard model on a square lattice using dynamical mean-field theory (DMFT). The …

Recent experimental results of angle-resolved photoemission spectroscopy suggested that
an additional strong nearest neighbor attraction in the Hubbard model might be significant …
