  • Strong-coupling ansatz for the one-dimensional Fermi gas in a harmonic potential 

    Levinsen, Jesper; Massignan, Pietro; Bruun, Georg M.; Parish, Meera M. (Science, 2015-07-24)
    Article
    Open Access
    A major challenge in modern physics is to accurately describe strongly interacting quantum many-body systems. One-dimensional systems provide fundamental insights because they are often amenable to exact methods. However, ...
  • Universality of the unitary Fermi gas: A few-body perspective 

    Levinsen, Jesper; Massignan, Pietro Alberto; Endo, Shimpei; Parish, Meera M (2017)
    Article
    Open Access
    We revisit the properties of the two-component Fermi gas with short-range interactions in three dimensions, in the limit where the s -wave scattering length diverges. Such a unitary Fermi gas pos- sesses universal thermodynamic ...
