Experimental realization of a long-range antiferromagnet in the Hubbard model with ultracold atoms
Anton Mazurenko, Christie S. Chiu, Geoffrey Ji +7
Many exotic phenomena in strongly correlated electron systems emerge from the interplay between spin and motional degrees of freedom. For example, doping an antiferromagnet gives r…
Microscopy of the interacting Harper-Hofstadter model in the few-body limit
M. Eric Tai, Alexander Lukin, Matthew Rispoli +7
The interplay of magnetic fields and interacting particles can lead to exotic phases of matter exhibiting topological order and high degrees of spatial entanglement. While these ph…
Topological order of mixed states in quantum many-body systems
Fabian Grusdt
Topological order has become a new paradigm to distinguish ground states of interacting many-body systems without conventional long-range order. Here we discuss possible extensions…
Interferometric Approach to Probing Fast Scrambling
Norman Y. Yao, Fabian Grusdt, Brian Swingle +4
Out-of-time-order correlation functions provide a proxy for diagnosing chaos in quantum systems. We propose and analyze an interferometric scheme for their measurement, using only…
Reservoir-induced Thouless pumping and symmetry protected topological order in open quantum chains
Dominik Linzner, Lukas Wawer, Fabian Grusdt +1
We introduce a classification scheme for symmetry protected topological phases applicable to stationary states of open systems based on a generalization of the many-body polarizati…
Quantum dynamics of ultracold Bose polarons
Yulia E. Shchadilova, Richard Schmidt, Fabian Grusdt +1
We analyze the dynamics of Bose polarons in the vicinity of a Feshbach resonance between the impurity and host atoms. We compute the radio-frequency absorption spectra for the case…
