Competition of fermion pairing, magnetism, and charge order in the spin-doped attractive Hubbard gas
Thomas Hartke, Botond Oreg, Chunhan Feng +7
The tension between fermion pairing and magnetism affects numerous strongly correlated electron systems, from high-temperature cuprates to twisted bilayer graphene. Exotic forms of…

Observation of Nagaoka Polarons in a Fermi-Hubbard Quantum Simulator
Martin Lebrat, Muqing Xu, Lev Haldar Kendrick +7
Quantum interference can deeply alter the nature of many-body phases of matter. In the paradigmatic case of the Hubbard model, Nagaoka famously proved that introducing a single iti…
