  • Dynamic structure factor of liquid He 4 across the normal-superfluid transition 

    Ferré Porta, Guillem; Boronat Medico, Jordi (2016-03-08)
    Article
    Open Access
    We have carried out a microscopic study of the dynamic structure factor of liquid He4 across the normal-superfluid transition temperature using the path integral Monte Carlo method. The ill-posed problem of the inverse ...
  • Luttinger parameter of quasi-one-dimensional para- H2 

    Ferré Porta, Guillem; Gordillo Bargueño, Maria Carmen; Boronat Medico, Jordi (2017-02-06)
    Article
    Open Access
    We have studied the ground-state properties of para-hydrogen in one dimension and in quasi-one-dimensional configurations using the path-integral ground-state Monte Carlo method. This method produces zero-temperature exact ...
  • A Monte Carlo approach to statics and dynamics of quantum fluids 

    Ferré Porta, Guillem (Universitat Politècnica de Catalunya, 2017-09-16)
    Doctoral thesis
    Open Access
    The main objective of the thesis is to study static and/or dynamic properties of a set of quantum fluids by means of quantum Monte Carlo techniques, mainly using the path integral formalism to obtain results both at zero ...
  • Observation of dynamic atom-atom correlation in liquid helium in real space 

    Dmowski, W.; Diallo, S. O.; Lokshin, K.; Ehlers, G.; Ferré Porta, Guillem; Boronat Medico, Jordi; Egami, T. (2017-05-04)
    Article
    Open Access
    Liquid He-4 becomes superfluid and flows without resistance below temperature 2.17 K. Superfluidity has been a subject of intense studies and notable advances were made in elucidating the phenomenon by experiment and theory. ...

  • Swimmers’ Collective Dynamics Modelization 

    Ferré Porta, Guillem (Universitat Politècnica de Catalunya, 2011-09-22)
    Master thesis
    Open Access
    English: We describe a new model in order to study the properties of collections of self-propelled particles swimming in a two-dimensional fluid. Our model consist in two types of particles, the first interacting with each ...
