Spin- and density-resolved microscopy of antiferromagnetic correlations in Fermi-Hubbard chains
Spin- and density-resolved microscopy of antiferromagnetic correlations in Fermi-Hubbard chains
The repulsive Hubbard Hamiltonian is one of the foundational models describing strongly correlated electrons and is believed to capture essential aspects of high temperature superconductivity. Ultracold fermions in optical lattices allow for the simulation of the Hubbard Hamiltonian with a unique control over kinetic energy, interactions and doping. A great …
