Transport controlled by Poincaré orbit topology in a driven inhomogeneous lattice gas by Alec Cao, Roshan Sajjad, Ethan Q. Simmons, Cora J. Fujiwara, Toshihiko Shimasaki, David M. Weld

“…In periodic quantum systems which are both homogeneously tilted and driven, the interplay between drive and Bloch oscillations controls transport dynamics. Using a quantum gas in a modulated optical lattice, we show experimentally that inhomogeneity of the applied force leads to a rich variety of dynamical behaviors controlled by the drive phase, from self-parametrically-modulated Bloch epicycles to adaptive driving of transport against a force gradient to modulation-enhanced monopole modes. …”

Quantum optical feedback control for creating strong correlations in many-body systems by Mazzucchi, G, Caballero-Benitez, S, Ivanov, D, Mekhov, I

Evaluation of time-dependent correlators after a local quench in iPEPS: hole motion in the t-J model by Claudius Hubig, Annabelle Bohrdt, Michael Knap, Fabian Grusdt, J. Ignacio Cirac

“…We showcase the method by simulating the t-J model after a single hole has been placed in the half-filled antiferromagnetic background and evaluating both return probabilities and spin correlation functions, as accessible in quantum gas microscopes.…”

Quantum-limited thermometry of a Fermi gas with a charged spin particle by Lorenzo Oghittu, Antonio Negretti

“…Lett. 125, 080402 (2020)0031-900710.1103/PhysRevLett.125.080402], where atomic neutral impurities were used as an in situ thermometer of the quantum gas. We find that the long-range character of the atom-ion interaction enhances the thermometer's sensitivity for certain system parameters. …”
