    • Microscopic interactions of melatonin, serotonin and tryptophan with zwitterionic phospholipid membranes 

      Martí Rabassa, Jordi; Lu, Huixia (2021-03-11)
      Article
      Open Access
      The interactions at the atomic level between small molecules and the main components of cellular plasma membranes are crucial for elucidating the mechanisms allowing for the entrance of such small species inside the cell. ...
    • The localization of non-backtracking centrality in networks and its physical consequences 

      Pastor Satorras, Romualdo; Castellano, Claudio (Nature, 2020-12-10)
      Article
      Open Access
      The spectrum of the non-backtracking matrix plays a crucial role in determining various structural and dynamical properties of networked systems, ranging from the threshold in bond percolation and non-recurrent epidemic ...
    • Bulk detection of time-dependent topological transitions in quenched chiral models 

      D'Errico, Alessio; Barboza, Raouf; Dauphin, Alexandre; Lewenstein, Maciej; Massignan, Pietro Alberto; Marrucci, Lorenzo; Cardano, Filippo; Di Colandrea, Francesco (American Physical Society, 2020-05)
      Article
      Open Access
      The topology of one-dimensional chiral systems is captured by the winding number of the Hamiltonian eigenstates. Here we show that this invariant can be read out by measuring the mean chiral displacement of a single-particle ...
    • Hydration structure and dynamics of the favipiravir antiviral drug: a molecular modelling approach 

      Skarmoutsos, Ioannis; Maurin, Guillaume; Guàrdia Manuel, Elvira; Samios, Jannis (2020-11-15)
      Article
      Open Access
      The hydration structure of the Favipiravir antiviral drug, at infinite dilution in water, was investigated by employing a systematic molecular modelling approach. An effective interaction potential model was employed for ...
    • Supersolid striped droplets in a Raman spin-orbit-coupled system 

      Sánchez Baena, Juan; Boronat Medico, Jordi; Mazzanti Castrillejo, Fernando Pablo (American Physical Society, 2020-11-09)
      Article
      Open Access
      We analyze the role played by quantum fluctuations on a Raman spin-orbit-coupled system in the stripe phase under attractive interspin interactions. We show that beyond-mean-field effects stabilize the collapse predicted ...
    • Reply to "comment on 'Berezinskii-Kosterlitz-Thouless transition in two-dimensional dipolar stripes' " 

      Bombín Escudero, Raul; Mazzanti Castrillejo, Fernando Pablo; Boronat Medico, Jordi (American Physical Society, 2020-10-19)
      Article
      Open Access
      This is a Reply to the Comment from F. Cinti and M. Boninsegni on our recent work on the Berezinskii-Kosterlitz-Thouless (BKT) phase transition in a two-dimensional dipolar system [Bombín, Mazzanti, and Boronat, Phys. Rev. ...
    • Towards a quantum Monte Carlo-based density functional including finite-range effects: excitation modes of a K 39 quantum droplet 

      Cikojevic, Viktor; Vranješ Markic, Leandra; Pi Pericay, Martí; Barranco Gómez, Manuel; Boronat Medico, Jordi (American Physical Society, 2020-09-25)
      Article
      Open Access
      Some discrepancies between experimental results on quantum droplets made of a mixture of 39K atoms in different hyperfine states and their analysis within extended Gross-Pitaevskii theory (which incorporates beyond mean-field ...
    • High-frequency contactless characterization of 2D materials. Graphene, WS2 

      Arcos Gutiérrez, David; Nuño Gómez, Daniel-Juan; Ametller Congost, Lluís; Ferrer Anglada, Núria (2020-12)
      Article
      Restricted access - publisher's policy
      The electrical conductivity of two-dimensional (2D) materials without any electrical contact can be obtained using two different methods: the terahertz time domain spectroscopy (THz-TDS) method, in the range from GHz up ...
    • Detecting topology through dynamics in interacting fermionic wires 

      Haller, Andreas; Massignan, Pietro Alberto; Rizzi, Mateo (American Physical Society, 2020-08-05)
      Article
      Open Access
      Probing the topological invariants of interacting systems stands as a grand and open challenge. Here we describe a dynamical method to characterize 1D chiral models, based on the direct observation of time-evolving bulk ...
    • Two-dimensional topological quantum walks in the momentum space of structured light 

      Massignan, Pietro Alberto; D'Errico, Alessio; Cardano, Filippo; Maffei, Maria; dauphin, Alexandre; Esposito, Chiara; Piccirillo, Bruno; Marrucci, Lorenzo; Lewenstein, Maciej; Barboza, Raouf (Optical Society of American (OSA), 2020-02-20)
      Article
      Open Access
      Quantum walks are powerful tools for quantum applications and for designing topological systems. Although they are simulated in a variety of platforms, genuine two-dimensional realizations are still challenging. Here we ...
