  • Quantum Brownian motion with inhomogeneous damping and diffusion 

    Massignan, Pietro; Lampo, Aniello; Wehr, Jan; Lewenstein, Maciej (APS Physics, 2015-03-23)
    Article
    Open Access
    We analyze the microscopic model of quantum Brownian motion, describing a Brownian particle interacting with a bosonic bath through a coupling which is linear in the creation and annihilation operators of the bath, but may ...
  • 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, ...
  • Weak Ergodicity Breaking of Receptor Motion in Living Cells Stemming from Random Diffusivity 

    Manzo, Carlo; Torreno-Pina, Juan A.; Massignan, Pietro; Lapeyre, Gerald J.; Lewenstein, Maciej; García Parajo, María F. (APS Physics, 2015-02-25)
    Article
    Open Access
    Molecular transport in living systems regulates numerous processes underlying biological function. Although many cellular components exhibit anomalous diffusion, only recently has the subdiffusive motion been associated ...
