Revealing Hidden Correlations in a Fermi-Hubbard system via Interaction Ramps
Botond Oreg, Carter Turnbaugh, Jens Hertkorn +2
We observe an enhanced visibility of charge-density-wave correlations in a cold-atom realization of the attractive Hubbard model following a rapid boost of the interaction strength…
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…
Doublon-hole correlations and fluctuation thermometry in a Fermi-Hubbard gas
Thomas Hartke, Botond Oreg, Ningyuan Jia +1
We report on the single atom and single site-resolved detection of the total density in a cold atom realization of the 2D Fermi-Hubbard model. Fluorescence imaging of doublons is a…
