Higher-order spin-hole correlations around a localized charge impurity by Yao Wang, Annabelle Bohrdt, Shuhan Ding, Joannis Koepsell, Eugene Demler, Fabian Grusdt

“…Analysis of higher-order correlation functions has become a powerful tool for investigating interacting many-body systems in quantum simulators, such as quantum gas microscopes. Experimental measurements of mixed spin-charge correlation functions in the 2D Hubbard have been used to study equilibrium properties of magnetic polarons and to identify coherent and incoherent regimes of their dynamics. …”

Self-Bayesian aberration removal via constraints for ultracold atom microscopy by Emine Altuntaş, I. B. Spielman

“…High-resolution imaging of ultracold atoms typically requires custom high numerical aperture (NA) optics, as is the case for quantum gas microscopy. These high NA objectives involve many optical elements, each of which contributes to loss and light scattering, making them unsuitable for quantum backaction limited “weak” measurements. …”

Probing eigenstate thermalization in quantum simulators via fluctuation-dissipation relations by Alexander Schuckert, Michael Knap

“…We first show how the emergence of fluctuation-dissipation relations from a nonequilibrium initial state can be observed for the two-dimensional (2D) Bose-Hubbard model in superconducting qubits or quantum gas microscopes. Then we focus on the long-range transverse field Ising model (LTFI), which can be realized with trapped ions. …”

Competition between weak quantum measurement and many-body dynamics in ultracold bosonic gases by Kozlowski, W

“…</p> <p>By taking into account the effect of measurement backaction we show that the measurement can efficiently compete with the local atomic dynamics of the quantum gas. This can generate long-range correlations and entanglement which in turn leads to macroscopic multimode oscillations across the whole lattice when the measurement is weak and correlated tunnelling, as well as selective suppression and enhancement of dynamical processes beyond the projective limit of the quantum Zeno effect in the strong measurement regime.…”
