      Projecte Final de Màster Oficial
      Accés obert
      One in three women worldwide experience physical or sexual violence, mostly by an intimate partner. Despite the large number of complaints, it is suspected that they represent only a small portion of the cases occurring, ...
    • Transferring filtered multiplicative structures in Homotopy Theory

      Projecte Final de Màster Oficial
      Accés restringit per acord de confidencialitat
      Realitzat a/amb:   Universitat de Barcelona
      Homotopy Theory focuses in the study of algebraic structures up to homotopy, a notion that allows to study algebraic invariants of topological and geometric origin. A classical technique in Homotopy Theory, introduced by ...
    • Twisted electrons as an imaging tool for probing chiral molecules in strong field ionization 

      Barcons Planas, Xavier (Universitat Politècnica de Catalunya, 2021-09-08)
      Projecte Final de Màster Oficial
      Accés obert
      Realitzat a/amb:   Universitat Autònoma de Barcelona / Universitat de Barcelona
      Orbital angular momentum (OAM) carried by vortex beams has seen an explosion of interest across fields and this is particularly true in attosecond physics. Given that twisted electrons have been shown to be sensitive to ...
    • Ultra short laser pulse characterization device based on disordered nonlinear crystals 

      Cubero Gamito, Guillermo (Universitat Politècnica de Catalunya, 2017-10-27)
