    • The nonlinear optics of first-order phase transitions 

      del Bosque Calvo, Alejandro (Universitat Politècnica de Catalunya, 2022-08-30)
      Projecte Final de Màster Oficial
      Accés obert
      Realitzat a/amb:   Institut de Ciències Fotòniques (ICFO) / Universitat Autònoma de Barcelona / Universitat de Barcelona
      Nonlinear effects are used to specially broaden the spectrum by the interaction with a material at high intensities. Here we study nonlinear effects in a light induced first-order phase transition of a thin layer of VO2. ...
    • 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)
      Projecte Final de Màster Oficial
      Accés obert
      Realitzat a/amb:   Institut de Ciències Fotòniques (ICFO) / Universitat de Barcelona / Universitat Autònoma de Barcelona
      In this project we build and test a compact and portable optical device for ultrashort pulse characterization. This setup allows the measurement of the pulse duration as well as its chirp parameter by using the so called ...
    • Ultracold dipolar bosons trapped in atomtronic circuits 

      Rovirola Metcalfe, Marc (Universitat Politècnica de Catalunya, 2022-07-19)
      Projecte Final de Màster Oficial
      Accés obert
      Realitzat a/amb:   Universitat de Barcelona / Institut de Ciències Fotòniques (ICFO) / Universitat Autònoma de Barcelona
      We consider a ring-shaped triple-well potential with few polar bosons characterized by a long-range and anisotropic interaction. By diagonalizing the extended Bose-Hubbard Hamiltonian, that treats sites as macroscopic ...
    • Ultrafast singlet fission dynamics in polymer-based thin-films measured by femtosecond transient absorption spectroscopy 

      Caravaca Crespo, Eva (Universitat Politècnica de Catalunya, 2022-08-26)
      Projecte Final de Màster Oficial
      Accés obert
      Realitzat a/amb:   Institut de Ciències Fotòniques (ICFO) / Universitat de Barcelona / Universitat Autònoma de Barcelona
      Singlet fission is a photophysical process which converts an excited singlet state into two independent triplet states. This has attracted significant attention for photovoltaic devices due to the fact that more than one ...
    • Use of three-dimensionally printed ß-tricalcium phosphate synthetic bone graft combined with recombinant human bone morphogenic protein-2 to treat a severe radial atrophic nonunion in a Yorkshire terrier 

      Franch, Jordi; Barba Serrahima, Albert; Steffaine Rappe, Katrin; Maazouz, Yassine; Ginebra Molins, Maria Pau (Wiley, 2020-07-08)
      Article
      Accés obert
      Realitzat a/amb:   Universitat Autònoma de Barcelona
      Objective: To describe a novel surgical approach to treat a critical-sized bone defect due to severe, radial atrophic nonunion in a miniature dog. Study design: Case report Animal: A 1-year-old Yorkshire terrier with a ...
