Revealing Hidden Correlations in a Fermi-Hubbard system via Interaction Ramps

Botond Oreg, Carter Turnbaugh, Jens Hertkorn, Martin Zwierlein, Ningyuan Jia

A rapid boost of interaction strength reveals hidden charge-density-wave correlations in the attractive Fermi-Hubbard model by converting nonlocal pairs into detectable doublons.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

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. The enhancement is largest in the strongly correlated regime where pairing is nonlocal.

C2weakest assumption

The rapid interaction boost associates nonlocal pairs into doublons marking the center of mass of the original pairs without otherwise disrupting or altering the underlying spatial correlations.

C3one line summary

Interaction ramps enhance visibility of nonlocal pair correlations in attractive Hubbard systems, distinguishing pseudogap from Fermi liquid phases via spin-charge measurements.
