Interaction-Driven Ferrimagnetic Stripes in the Extended Hubbard Model
Chunhan Feng, Miguel A. Morales, Shiwei Zhang
Long-range interactions can qualitatively reorganize correlated-electron ground states. In the square-lattice Hubbard model, on-site repulsion produces antiferromagnetic spin and c…
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…
In search of exotic pairing in the Hubbard model: many-body computation and quantum gas microscopy
Chunhan Feng, Thomas Hartke, Yuan-Yao He +5
Pair density waves and exotic superconductivity have long been of strong interest, and have attracted much recent attention. We present a joint theoretical and experimental explora…
A neutral-atom Hubbard quantum simulator in the cryogenic regime
Muqing Xu, Lev Haldar Kendrick, Anant Kale +6
Ultracold fermionic atoms in optical lattices offer pristine realizations of Hubbard models, which are fundamental to modern condensed matter physics. Despite significant advanceme…
