Classifying Snapshots of the Doped Hubbard Model with Machine Learning
Annabelle Bohrdt, Christie S. Chiu, Geoffrey Ji +6
Quantum gas microscopes for ultracold atoms can provide high-resolution real-space snapshots of complex many-body systems. We implement machine learning to analyze and classify suc…
Imaging magnetic polarons in the doped Fermi-Hubbard model
Joannis Koepsell, Jayadev Vijayan, Pimonpan Sompet +6
Polarons are among the most fundamental quasiparticles emerging in interacting many-body systems, forming already at the level of a single mobile dopant. In the context of the two-…
Coupling ultracold matter to dynamical gauge fields in optical lattices: From flux-attachment to Z2 lattice gauge theories
Luca Barbiero, Christian Schweizer, Monika Aidelsburger +3
Artificial magnetic fields and spin-orbit couplings have been recently generated in ultracold gases in view of realizing topological states of matter and frustrated magnetism in a…
String patterns in the doped Hubbard model
Christie S. Chiu, Geoffrey Ji, Annabelle Bohrdt +6
Understanding strongly correlated quantum many-body states is one of the most difficult challenges in modern physics. For example, there remain fundamental open questions on the ph…
Signatures of correlated magnetic phases in the local two-particle density matrix
Sebastian Huber, Fabian Grusdt, Matthias Punk
Experiments with quantum gas microscopes have started to explore the antiferromagnetic phase of the two-dimensional Fermi-Hubbard model and effects of doping with holes away from h…
Meson formation in mixed-dimensional t-J models
Fabian Grusdt, Zheng Zhu, Tao Shi +1
Surprising properties of doped Mott insulators are at the heart of many quantum materials, including transition metal oxides and organic materials. The key to unraveling complex ph…
