    • The fundamental group of Kaehler manifolds 

      Amorós Torrent, Jaume (1997)
      Article
      Accés obert
      It studies the fundamental group of complex algebraic varieties, in its Betti, Hodge and de Rham realizations. This study has been carried out both in the absolute case, i.e. fundamental groups of such varieties, and in ...

    • The matter-ekpyrotic bounce scenario in Loop Quantum Cosmology 

      Haro Cases, Jaume; Amorós Torrent, Jaume; Aresté Saló, Llibert (2017-09-01)
      Article
      Accés obert
      We will perform a detailed study of the matter-ekpyrotic bouncing scenario in Loop Quantum Cosmology using the methods of the dynamical systems theory. We will show that when the background is driven by a single scalar ...

    • The Peebles–Vilenkin quintessential inflation model revisited 

      Haro Cases, Jaume; Amorós Torrent, Jaume; Pan, Supriya (springer-Verlag, 2019-06-01)
      Article
      Accés obert
      We review the well-known Peebles–Vilenkin (PV) quintessential inflation model and discuss its possible improvements in agreement with the recent observations. The improved PV model depends only on two parameters: the ...

    • Topologia. Apunts 

      Barja Yáñez, Miguel Ángel; Pascual Gainza, Pere; Roig Martí, Agustín; Carreras, Judit; Amorós Torrent, Jaume (Universitat Politècnica de Catalunya, 1998)
      Apunts
      Accés obert

    • Understanding the phenomenology of interacting dark energy scenarios and their theoretical bounds 

      Pan, Supriya; Haro Cases, Jaume; Yang, Weiqiang; Amorós Torrent, Jaume (American Physical Society (APS), 2020-06-15)
      Article
      Accés obert
      Nongravitational interaction between dark matter and dark energy has been considered in a spatially flat Friedmann-Lemaître-Robertson-Walker (FLRW) universe. The interaction rate is assumed to be linear in the energy ...

    • Viability of the Matter Bounce Scenario 

      Haro Cases, Jaume; Amorós Torrent, Jaume (Institute of Physics (IOP), 2015)
      Article
      Accés obert
      It is shown that teleparallel F(T) theories of gravity combined with Loop Quantum Cosmology support a Matter Bounce Scenario which is an alternative to the inflation scenario in the Big Bang paradigm. It is checked that ...

    • Viability of the matter bounce scenario in Loop Quantum Cosmology from BICEP2 last data 

      Haro Cases, Jaume; Amorós Torrent, Jaume (2014-08-12)
      Article
      Accés obert
      The CMB map provided by the Planck project constrains the value of the ratio of tensor-to-scalar perturbations, namely r, to be smaller than 0.11 (95 % CL). This bound rules out the simplest models of inflation. However, ...

    • Viability of the matter bounce scenario in F(T) gravity and Loop Quantum Cosmology forgeneral potentials 

      Haro Cases, Jaume; Amorós Torrent, Jaume (2014-12-01)
      Article
      Accés obert
      We consider the matter bounce scenario in F (T) gravity and Loop Quantum Cosmology (LQC) for phenomenological potentials that at early times provide a nearly matter dominated Universe in the contracting phase, having a ...
