    • The origin of the period-2T/7 quasi-breathing in disk-shaped Gross-Pitaevskii breathers 

      Torrents Monegal, Jordi; Dunjko, Vedran; Gonchenko5, Marina; Astrakharchik, Grigori; Olshanii, Maxim (2022-03-14)
      Article
      Accés obert
      We address the origins of the quasi-periodic breathing observed in [Phys. Rev.\ X vol. 9, 021035 (2019)] in disk-shaped harmonically trapped two-dimensional Bose condensates, where the quasi-period Tquasi-breathing~~2T/7 ...

    • Scale-free behavioral cascades and effective leadership in schooling fish 

      Múgica Gallart, Julia; Torrents Monegal, Jordi; Cristin, Javier; Puy Contreras, Andreu; Miguel Lopez, M. Del Carmen; Pastor Satorras, Romualdo (Nature, 2022-06-24)
      Article
      Accés obert
      Behavioral contagion and the presence of behavioral cascades are natural features in groups of animals showing collective motion, such as schooling fish or grazing herbivores. Here we study empirical behavioral cascades ...

    • Modeling and simulation of lipid membranes 

      Martí Rabassa, Jordi; Calero, Carles (Multidisciplinary Digital Publishing Institute (MDPI), 2022-08-03)
      Llibre
      Accés obert

    • Van der Waals five-body size-energy universality 

      Stipanovic, P.; Vranješ Markic, Leandra; Boronat Medico, Jordi (Nature, 2022-12-01)
      Article
      Accés obert
      A universal relationship between scaled size and scaled energy is explored in five-body self-bound quantum systems. The ground-state binding energy and structure properties are obtained by means of the diffusion Monte Carlo ...

    • Supersolidity in the second layer of para-H2 adsorbed on graphite 

      Gordillo Bargueño, Maria Carmen; Boronat Medico, Jordi (American Physical Society (APS), 2022-03-03)
      Article
      Accés restringit per política de l'editorial
      We calculated the phase diagram of the second layer of para-H2 adsorbed on graphite using quantum Monte Carlo methods. The second layer shows an incommensurate triangular crystal structure. By using a symmetric wave function, ...

    • Modeling and simulation of lipid membranes 

      Martí Rabassa, Jordi; Calero, Carles (Multidisciplinary Digital Publishing Institute (MDPI), 2022-05-25)
      Article
      Accés obert
      Cell membranes separate the interior of cells and the exterior environment, providing protection, controlling the passage of substances, and governing the interaction with other biomolecules and signalling processes. They ...

    • Exactly solvable system of one-dimensional trapped bosons with short- and long-range interactions 

      Astrakharchik, Grigori (American Institute of Physics (AIP), 2020-11-25)
      Article
      Accés obert
      We introduce a model of trapped bosons with contact interactions as well as Coulomb repulsion or gravitational attraction in one spatial dimension. We find the exact ground-state energy and many-body wave function. The ...

    • Coordination and growth: the Stag Hunt game on evolutionary networks 

      Starnini, Michele; Poncela, Julia; moreno, yamir; sanchez, angel (Institute of Physics (IOP), 2011-05-06)
      Article
      Accés obert
      Recently, the study of evolutionary games on networks has attracted great interest, focused mainly on the problem of the emergence of cooperation. A well studied framework for this problem is the Prisoner’s Dilemma game ...

    • The interconnected wealth of nations: shock propagation on global trade-investment multiplex networks 

      Starnini, Michele; Boguña Espinal, Marian; Serrano, M.Angels (Nature, 2019-09-11)
      Article
      Accés obert
      The increasing integration of world economies, which organize in complex multilayer networks of interactions, is one of the critical factors for the global propagation of economic crises. We adopt the network science ...

    • Collective response to media coverage of the COVID-19 pandemic on Reddit and Wikipedia: mixed-methods analysis 

      Gozzi, Nicolò; Starnini, Michele; Panisson, André; Paolotti, Daniela; Perra, Nicola (JMIR, 2020-10-12)
      Article
      Accés obert
      Background: The exposure and consumption of information during epidemic outbreaks may alter people’s risk perception and trigger behavioral changes, which can ultimately affect the evolution of the disease. It is thus of ...

    • Role of oxygen vacancy ordering and channel formation in tuning intercalation pseudocapacitance in Mo single-ion-implanted CeO2–x nanoflakes 

      Zheng, Xiaoran; Mofarah, Sajjad S.; Cen, Alan; Cazorla Silva, Claudio; Haque, Enamul; Chen, Ewing Y.; Atanacio, Armand J.; Manohar, Madhura; Vutukuri, Corey; Abraham, Joel Luke; Koshy, Pramod; Sorrell, Charles C. (2021-12-22)
      Article
