La seva activitat de recerca està dirigida al desenvolupament de mètodes analítics i numèrics per sistemes dinàmics, gaudint de lideratge científic en diversos temes, com Integrabilitat, Objectes invariants, Teoria K.A.M., Camps vectorials plans i aplicacions a neurociència, Mètode de Poincaré-Melnikov, Escissió exponencialment petita de separatrius, Difusió, Mecànica Celest i Astrodinàmica.
La qualitat d'aquesta activitat es reflecteix tant en la qualitat i quantitat de publicacions, algunes d'elles en col.laboració amb grups internacionals de primera línia, com en la gestió científica desenvolupada, plasmada en l'organització de múltiples events (congressos i jornades , programes de recerca, xarxes temàtiques, etc.), la participació en diversos comitès editorials de revistes de prestigi reconegut, així com en una àmplia formació doctoral.

  • Dynamics in the centre manifold around equilibrium points in periodically perturbed three-body problems 

    Le Bihan, Bastien; Masdemont Soler, Josep; Gomez Muntané, Gerard; Lizy-Destrez, Stephanie (2016)
    Text en actes de congrés
    Accés obert
    A new application of the parameterization method is pre- sented to compute invariant manifolds about the equilib- rium points of Periodically Perturbed Three-Body Problems ( PPTBP ). These techniques are applied to obtain ...
  • Arnold's mechanism of diffusion in the spatial circular restricted three-body problem: A semi-analytical argument 

    Delshams Valdés, Amadeu; Gidea, Marian; Roldán, Pablo (2016-11-01)
    Article
    Accés restringit per política de l'editorial
    We consider the spatial circular restricted three-body problem, on the motion of an infinitesimal body under the gravity of Sun and Earth. This can be described by a 3-degree of freedom Hamiltonian system. We fix an energy ...
  • Warp evidence in precessing galactic bar models 

    Sanchez Martin, P; Romero Gómez, Mercè; Masdemont Soler, Josep (EDP Sciences, 2016-04-01)
    Article
    Accés obert
    Most galaxies have a warped shape when they are seen edge-on. The reason for this curious form is not completely known so far, so in this work we apply dynamical system tools to contribute to its explanation. Starting from ...
  • Quasi-periodically driven quantum systems 

    Verdeny, Albert; Puig Sadurní, Joaquim; Mintert, Florian (Walter De Gruyter, 2016-10-10)
    Article
    Accés obert
    Floquet theory provides rigorous foundations for the theory of periodically driven quantum systems. In the case of non-periodic driving, however, the situation is not so well understood. Here, we provide a critical review ...
  • Full analysis of small hypercycles with shortcircuits in prebiotic evolution 

    Lázaro Ochoa, José Tomás; Guillamon Grabolosa, Antoni; Fontich, Ernest; Sardañés, Josep (2017-01-05)
    Article
    Accés restringit per política de l'editorial
    It is known that hypercycles are sensitive to the so-called parasites and short-circuits. While the impact of parasites has been widely investigated for well-mixed and spatial hypercycles, the effect of short-circuits in ...
  • Exponentially small asymptotic formulas for the length spectrum in some billiard tables 

    Martín, P.; Ramírez Ros, Rafael; Tamarit Sariol, A. (2016-04-05)
    Article
    Accés restringit per política de l'editorial
    Let q = 3 be a period. There are at least two (1, q)-periodic trajectories inside any smooth strictly convex billiard table. We quantify the chaotic dynamics of axisymmetric billiard tables close to their boundaries by ...
  • The social network around influenza vaccination in health care workers: A cross-sectional study 

    Llupià, Anna; Puig Sadurní, Joaquim; Mena, Guillermo; Bayas, José M.; Trilla, Antoni (2016-11-24)
    Article
    Accés obert
    Background: Influenza vaccination coverage remains low among health care workers (HCWs) in many health facilities. This study describes the social network defined by HCWs’ conversations around an influenza vaccination ...
  • Growth of Sobolev norms for the analytic NLS on T-2 

    Guàrdia Munarriz, Marcel; Sandhaus, Evan; Procesi, M. (2016-10-01)
    Article
    Accés obert
    We consider the completely resonant non-linear Schrödinger equation on the two dimensional torus with any analytic gauge invariant nonlinearity. Fix s>1. We show the existence of solutions of this equation which achieve ...
  • A Second Order Expansion of the Separatrix Map for Trigonometric Perturbations of a Priori Unstable Systems 

    Guàrdia Munarriz, Marcel; Kaloshin, Vadim; Zhang, Jianlu (2016-11-01)
    Article
    Accés obert
    In this paper we study a so-called separatrix map introduced by Zaslavskii–Filonenko (Sov Phys JETP 27:851–857, 1968) and studied by Treschev (Physica D 116(1–2):21–43, 1998; J Nonlinear Sci 12(1):27–58, 2002), Piftankin ...
  • Oscillatory orbits in the restricted elliptic planar three body problem 

    Guàrdia Munarriz, Marcel; Martín, Pau; Sabbagh, Lara; Martínez-Seara Alonso, M. Teresa (Southwest Missouri State University, 2017-01-01)
    Article
    Accés obert
    The restricted planar elliptic three body problem models the motion of a massless body under the Newtonian gravitational force of two other bodies, the primaries, which evolve in Keplerian ellipses. A trajectory is called ...
