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.

  • Central configurations of the planar coorbial satellite problem 

    Cors Iglesias, Josep Maria; Llibre Saló, Jaume; Ollé Torner, Mercè (2004-10)
    Article
    Accés obert
    We study the planar central configurations of the 1 +n body problem where one mass is large and the other n masses are infinitesimal and equal. We find analytically all these central configurations when 2=n=4. Numerically, ...
  • Phasic firing and coincidence detection by subthreshold negative feedback: divisive or subtractive or, better, both 

    Huguet Casades, Gemma; Meng, Xiangying; Rinzel, John (2017-02-02)
    Article
    Accés obert
    Phasic neurons typically fire only for a fast-rising input, say at the onset of a step current, but not for steady or slow inputs, a property associated with type III excitability. Phasic neurons can show extraordinary ...
  • On the length and area spectrum of analytic convex domains 

    Martín, Pau; Ramírez Ros, Rafael; Tamarit Sariol, A. (2016-01)
    Article
    Accés obert
    Area-preserving twist maps have at least two different (p, q)-periodic orbits and every (p, q)-periodic orbit has its (p, q)-periodic action for suitable couples (p, q). We establish an exponentially small upper bound for ...
  • Solar radiation pressure assisted transfers between Lissajous orbits of the Sun-Earth system 

    Stefania, Soldini; Gomez Muntané, Gerard; Masdemont Soler, Josep; Camilla, Colombo; Walker, Scott (2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    This article investigates a propellant-free transfer between Lissa jous orbits in the Sun-Earth system modelled as a photo-gravitational circular restricted three body p roblem. The geometry of the phase space around the ...
  • On the asymptotic wavenumber of spiral waves in lambda - omega systems 

    Aguareles Carrero, Maria; Baldomá Barraca, Inmaculada; Martínez-Seara Alonso, M. Teresa (2016-01-01)
    Article
    Accés restringit per política de l'editorial
    In this paper we consider spiral wave solutions of a general class of $\lambda -\omega $ systems with a small twist parameter q and we prove that the asymptotic wavenumber of the spirals is a ${{\mathcal{C}}^{\infty}}$ ...
  • On bifurcations of homoclinic tangencies in area-preserving maps on non-orientable manifolds 

    Delshams Valdés, Amadeu; Gonchenko, Marina; Gonchenko, Sergey (Springer, 2016)
    Capítol de llibre
    Accés restringit per política de l'editorial
    We study bifurcations of non-orientable area-preserving maps with quadratic homoclinic tangencies. We study the case when the maps are given on non-orientable two-dimensional manifolds. We consider one and two parameter ...
  • 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 ...
