    • Universality of size-energy ratio in four-body systems 

      Stipanovic, P.; Vranješ Markic, Leandra; Gudyma, Andrii; Boronat Medico, Jordi (Nature, 2019-04-18)
      Article
      Accés obert
      Universal relationship of scaled size and scaled energy, which was previously established for two- and three-body systems in their ground state, is examined for four-body systems, using Quantum Monte Carlo simulations. We ...

    • Universality of the unitary Fermi gas: A few-body perspective 

      Levinsen, Jesper; Massignan, Pietro Alberto; Endo, Shimpei; Parish, Meera M (2017)
      Article
      Accés obert
      We revisit the properties of the two-component Fermi gas with short-range interactions in three dimensions, in the limit where the s -wave scattering length diverges. Such a unitary Fermi gas pos- sesses universal thermodynamic ...

    • Universos paralelos 

      Barceló Garcia, Miquel (1997-03)
      Article
      Accés obert

    • 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 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 ...

    • Water absorbed by polyaniline emeraldine tends to organize, forming nanodrops 

      Casanovas, Jordi; Canales Gabriel, Manel; Fabregat Jové, Georgina; Meneguzzi, Álvaro; Alemán Llansó, Carlos (2012)
      Article
      Accés restringit per política de l'editorial
      Interactions, in terms of both binding energies and microscopic organization, of water molecules absorbed by hydrophilic polyaniline emeraldine base have been investigated using quantum mechanical calculations, molecular ...

    • Weak value amplification: a view from quantum estimation theory that highlights what it is and what isn’t 

      Pérez Torres, Juan; Salazar Serrano, Luis Jose (Macmillan Publishers, 2016-02-01)
      Article
      Accés obert
      Weak value amplification (WVA) is a concept that has been extensively used in a myriad of applications with the aim of rendering measurable tiny changes of a variable of interest. In spite of this, there is still an on-going ...

    • Work analysis of one-dimensional driven quantum systems 

      Arazo Sánchez, Maria (Universitat Politècnica de Catalunya, 2018-09-06)
      Projecte Final de Màster Oficial
      Accés obert
      We introduce the probability distribution of work performed on a one- dimensional quantum system and study the cases of a single particle in a harmonic or finite well potential and of a Bose-Einstein condensate in a finite ...
