The structures, the phase diagrams, and the appearance of a neutron resonance signaling
an unconventional superconducting state provide phenomenological evidence relating the …

Accurate simulations of the two-dimensional (2D) Hubbard model constitute one of the most
challenging problems in condensed matter and quantum physics. Here we develop a …

We report on the site-resolved observation of characteristic states of the two-dimensional
repulsive Fermi-Hubbard model, using ultracold K 40 atoms in an optical lattice. By varying …

We tutorially review the determinantal Quantum Monte Carlo method for fermionic systems,
using the Hubbard model as a case study. Starting with the basic ingredients of Monte Carlo …

The SU (2) symmetric Fermi-Hubbard model (FHM) plays an essential role in strongly
correlated fermionic many-body systems. In the one particle per site and strongly interacting …

We investigate ground state and finite temperature properties of the half-filled Hubbard
model on a honeycomb lattice using quantum Monte Carlo and series expansion …

One of the major challenges in realizing antiferromagnetic and superfluid phases in optical
lattices is the ability to cool fermions. We determine constraints on the entropy for observing …

The 2D Hubbard model with nearest-neighbor hopping on the square lattice and an average
of one electron per site is known to undergo an extended crossover from metallic to …

We report on the controlled creation of a valence bond state of delocalized effective-spin
singlet and triplet dimers by means of a bichromatic optical superlattice. We demonstrate a …

We present evidence for an isostructural, first-order Mott transition in MnO at 105±5 GPa,
based on high-resolution x-ray emission spectroscopy and angle-resolved x-ray diffraction …
