Higher-Order Spin-Hole Correlations around a Localized Charge Impurity
Yao Wang, Annabelle Bohrdt, Joannis Koepsell +2
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. Ex…
Dominant fifth-order correlations in doped quantum anti-ferromagnets
A. Bohrdt, Y. Wang, J. Koepsell +3
Traditionally one and two-point correlation functions are used to characterize many-body systems. In strongly correlated quantum materials, such as the doped 2D Fermi-Hubbard syste…
Robust Bilayer Charge-Pumping for Spin- and Density-Resolved Quantum Gas Microscopy
Joannis Koepsell, Sarah Hirthe, Dominik Bourgund +5
Quantum gas microscopy has emerged as a powerful new way to probe quantum many-body systems at the microscopic level. However, layered or efficient spin-resolved readout methods ha…
Time-Resolved Observation of Spin-Charge Deconfinement in Fermionic Hubbard Chains
Jayadev Vijayan, Pimonpan Sompet, Guillaume Salomon +6
Elementary particles such as the electron carry several quantum numbers, for example, charge and spin. However, in an ensemble of strongly interacting particles, the emerging degre…
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-…
Direct observation of incommensurate magnetism in Hubbard chains
Guillaume Salomon, Joannis Koepsell, Jayadev Vijayan +5
The interplay between magnetism and doping is at the origin of exotic strongly correlated electronic phases and can lead to novel forms of magnetic ordering. One example is the eme…
