The hubbard model

DP Arovas, E Berg, SA Kivelson… - Annual review of …, 2022 - annualreviews.org
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 …

Solutions of the two-dimensional Hubbard model: benchmarks and results from a wide range of numerical algorithms

JPF LeBlanc, AE Antipov, F Becca, IW Bulik, GKL Chan… - Physical Review X, 2015 - APS
Numerical results for ground-state and excited-state properties (energies, double

Intermediate coupling model of the cuprates

T Das, RS Markiewicz, A Bansil - Advances in Physics, 2014 - Taylor & Francis
We review the intermediate coupling model for treating electronic correlations in the
cuprates. Spectral signatures of the intermediate coupling scenario are identified and used …

Superconductivity in the repulsive Hubbard model: An asymptotically exact weak-coupling solution

S Raghu, SA Kivelson, DJ Scalapino - Physical Review B—Condensed Matter …, 2010 - APS
We study the phase diagram of the Hubbard model in the limit where U, the onsite repulsive
interaction, is much smaller than the bandwidth. We present an asymptotically exact …

Temperature-flow renormalization group and the competition between superconductivity and ferromagnetism

C Honerkamp, M Salmhofer - Physical Review B, 2001 - APS
We derive a differential equation for the one-particle-irreducible vertex functions of
interacting fermions as a function of the temperature. Formally, these equations correspond …

Superconducting order of from a three-dimensional microscopic model

Magnetic and superconducting instabilities of the hubbard model at the van hove filling

C Honerkamp, M Salmhofer - Physical Review Letters, 2001 - APS
We use a novel temperature-flow renormalization group technique to analyze magnetic and
superconducting instabilities in the two-dimensional t− t′ Hubbard model for particle …

The superconductivity of Sr2RuO4 under c-axis uniaxial stress

F Jerzembeck, HS Røising, A Steppke… - Nature …, 2022 - nature.com
Applying in-plane uniaxial pressure to strongly correlated low-dimensional systems has
been shown to tune the electronic structure dramatically. For example, the unconventional …

Incommensurate magnetic order and phase separation in the two-dimensional Hubbard model with nearest-and next-nearest-neighbor hopping
