First signs of stripe formation

17 Jan 2025

In a cold-atom Fermi Hubbard model, researchers observed correlations between hole dopants and indications of stripes that are associated with superconductivity, opening up novel insights into the behaviour of exotic quantum phases.

In a new study, researchers from the MCQST, the Max Planck Institute of Quantum Optics and the LMU under the lead of Timon Hilker demonstrated evidence of stripe formation, i.e. extended structures in the density pattern, in a cold-atom Fermi-Hubbard system. By using a quantum gas microscope and a special mixed-dimensional geometry, they were able to observe unique higher-order correlations in spin and charge densities related to those seen in some high-temperature superconducting materials.
