    • Effects of Fermion Exchange on the Polarization of Exciton Condensates 

      Combescot, Monique; Combescot, Roland; Alloing, Mathieu; Dubin, François (APS Physics, 2015-03-04)
      Article
      Accés obert
      Exchange interaction is responsible for the stability of elementary boson condensates with respect to momentum fragmentation. This remains true for composite bosons when single fermion exchanges are included but spin ...

    • 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; Garcia-Parajo, Maria F. (APS Physics, 2015-02-25)
      Article
      Accés obert
      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 ...

    • Conformal data from finite entanglement scaling 

      Stojevic, Vid; Haegeman, Jutho; McCulloch, I. P.; Tagliacozzo, Luca; Verstraete, Frank (APS Physics, 2015-01-20)
      Article
      Accés obert
      In this paper, we apply the formalism of translation invariant (continuous) matrix product states in the thermodynamic limit to (1 + 1)-dimensional critical models. Finite bond dimension bounds the entanglement entropy ...

    • Quantum mechanics: No more fields 

      Lewenstein, Maciej (Nature Publishing group, 2015-01-05)
      Article
      Accés obert
      A self-accelerating electronic wave packet can acquire a phase akin to the Aharonov–Bohm effect, but in the absence of a magnetic field.

    • Quantum many-body systems out of equilibrium 

      Eisert, J.; Friesdorf, M.; Gogolin, Christian (Nature Publishing group, 2015-02-03)
      Article
      Accés obert
      How do closed quantum many-body systems driven out of equilibrium eventually achieve equilibration? And how do these systems thermalize, given that they comprise so many degrees of freedom? Progress in answering these—and ...

    • Tensor Networks for Lattice Gauge Theories with continuous groups 

      Tagliacozzo, Luca; Celi, Alessio; Lewenstein, Maciej (ACS Publications, 2014-11-06)
      Article
      Accés obert
      We discuss how to formulate lattice gauge theories in the tensor-network language. In this way, we obtain both a consistent-truncation scheme of the Kogut-Susskind lattice gauge theories and a tensornetwork variational ...
