Correlations generated from high-temperature states: nonequilibrium dynamics in the Fermi-Hubbard model

Understand

We study interaction quenches of the Fermi-Hubbard model initiated from various high-temperature and high-energy states, motivated by cold atom experiments, which currently operate above the ordering temperature(s).

• We analytically calculate the dynamics for quenches from these initial states, which are often strongly-interacting, to the non-interacting limit.
• Even for high-temperature uncorrelated initial states, transient connected correlations develop.
• These correlations share many features for all considered initial states.
