We perform an ab initio comparison between nonequilibrium dynamical mean-field theory and optical lattice experiments by studying the time evolution of double occupations in the periodically driven Fermi-Hubbard model. For off-resonant driving, the range of validity of a description in terms of an effective static Hamiltonian is determined and its breakdown due to energy absorption close to resonance is demonstrated. For near-resonant driving, we investigate the response to a change in driving…

Dynamical quantum phase transitions in the one-dimensional extended Fermi–Hubbard model

We study the emergence of dynamical quantum phase transitions (DQPTs) in a half-filled one-dimensional lattice described by the extended Fermi–Hubbard model, based on tensor network simulations.

Rabi-resonant behavior of periodically driven correlated fermion systems

Energy redistribution and spatiotemporal evolution of correlations after a sudden quench of the Bose-Hubbard model

This work uses an optical lattice quantum simulator of the Bose-Hubbard model to study dynamics far from equilibrium after a quantum quench, and successfully confirms the energy conservation law in the one- and three-dimensional systems and extracts the propagation velocity of the single-particle correlation.

Suppressing Dissipation in a Floquet-Hubbard System

The concept of `Floquet engineering' relies on an external periodic drive to realise novel, effectively static Hamiltonians. This technique is being explored in experimental platforms across physics,

Nonequilibrium dynamical mean-field calculations based on the noncrossing approximation and its generalizations

We solve the impurity problem which arises within nonequilibrium dynamical mean-field theory for the Hubbard model by means of a self-consistent perturbation expansion around the atomic limit. While

It is shown that driving a hexagonal lattice compared to a simple cubic lattice allows us to modulate the system up to 1 s, corresponding to hundreds of tunneling times, with only minor atom loss.

Resonant Thermalization of Periodically Driven Strongly Correlated Electrons.

The dynamics of the Fermi-Hubbard model driven by a time-periodic modulation of the interaction within nonequilibrium dynamical mean-field theory are studied and the existence of a critical frequency at which the system rapidly thermalizes despite the large interaction is shown.

The Schrieffer-Wolff transformation is applied to the periodically driven, strongly interacting Fermi-Hubbard model, for which it is identified two regimes resulting in different effective low-energy Hamiltonians.

Dynamical control of matter-wave tunneling in periodic potentials.

Measurements of dynamical suppression of interwell tunneling of a Bose-Einstein condensate (BEC) in a strongly driven optical lattice show that the strong shaking does not destroy the phase coherence of the BEC, opening up the possibility of realizing quantum phase transitions by using the shaking strength as the control parameter.

Floquet Engineering of Correlated Tunneling in the Bose-Hubbard Model with Ultracold Atoms.

The experimental implementation of tunable occupation-dependent tunneling in a Bose-Hubbard system of ultracold atoms via time-periodic modulation of the on-site interaction energy is reported, finding that the tunneling rate explicitly depends on the atom number difference in neighboring lattice sites.

The many-body formalism for dynamical mean-field theory is extended to treat nonequilibrium problems by examining the transient decay of the oscillating current that is driven by a large electric field turned on at time t=0.
