  1. Dec 21, 2023The relation between d-wave superconductivity and stripes is fundamental to the understanding of ordered phases in cuprates. While experimentally both phases are found in close proximity, numerical studies on the related Fermi-Hubbard model have long been investigating whether stripes precede, compete or coexist with superconductivity. Such stripes are characterised by interleaved charge and ...
  2. Here we show first signatures of stripes in a cold-atom Fermi-Hubbard quantum simulator. By engineering a mixed-dimensional system, we increase their typical energy scales to the spin exchange energy, enabling us to access the interesting crossover temperature regime where stripes begin to form . We observe extended, attractive correlations ...

    Here we show, to our knowledge, the first signatures of individual stripes in a cold-atom Fermi-Hubbard quantum simulator using mixed-dimensional (mixD) settings. Increasing the energy scale of hole-hole attraction to the spin exchange energy, we access the interesting crossover temperature regime in which stripes begin to form 11. We observe ...

  6. 6 days agoIn 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 ...
