    • Does Vo2 host a transient monoclinic metallic phase? 

      Vidas Almohalla, Luciana; Martínez Moreno, Elías; Pérez Salinas, Daniel; Wall, Simon (2020-08-27)
      Article
      Accés obert
      Ultrafast phase transitions induced by femtosecond light pulses present a new opportunity for manipulating the properties of materials. Understanding how these transient states are different from, or similar to, their ...

    • Experimental and Theoretical Study of Second Harmonic Generation from an ITO Nanolayer 

      Rodríguez Suñé, Laura; Scalora, Michael; Johnson, Allan; Cojocaru, Crina; Akozbek, Neset; Coppens, Zachary; Pérez Salinas, Daniel; Wall, Simon; Trull Silvestre, José Francisco (Institute of Electrical and Electronics Engineers (IEEE), 2020)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      We present an experimental study of second harmonic generation from a 20nm-thick indium tin oxide layer in the proximity of its epsilon-near-zero condition. We report measurements of second harmonic efficiencies as a ...

    • Inhomogeneity and disorder in ultrafast phase transitions 

      Pérez Salinas, Daniel (Universitat Politècnica de Catalunya, 2022-01-31)
      Tesi
      Accés obert
      In the recent decades, there has been a surge of interest in the wide array of emergent phenomena found in strongly correlated materials. Understanding the inner workings of this type of systems is a major challenge due ...

    • Optical control of thermal diffusion in phase change materials 

      Pérez Salinas, Daniel (Universitat Politècnica de Catalunya, 2016-09-09)
      Projecte Final de Màster Oficial
      Accés obert
      The long term crystallization of amorphous Ge2Sb2Te5 (GST) induced by femtosecond laser pulses has been numerically and experimentally studied. Simulations of the evolution of temperature and crystalline fraction after a ...

    • Second harmonic generation from an ITO nanolayer: experiment versus theory 

      Rodríguez Suñé, Laura; Scalora, Michael; Johnson, Allan; Cojocaru, Crina; Akozbek, Neset; Coppens, Zachary; Pérez Salinas, Daniel; Wall, Simon; Trull Silvestre, José Francisco (International Society for Photo-Optical Instrumentation Engineers (SPIE), 2020)
      Text en actes de congrés
      Accés obert
      We report a comparative experimental and theoretical study of second harmonic generation from a 20nm-thick indium tin oxide nanolayer in the proximity of the epsilon-near-zero condition. We record the efficiency of the ...

    • Study of second and third harmonic generation from an indium tin oxide nanolayer: Influence of nonlocal effects and hot electrons 

      Rodríguez Suñé, Laura; Escalora, M.; Johnson, Allan; Cojocaru, Crina; Akozbek, Neset; Coppens, Zachary; Pérez Salinas, Daniel; Wall, Simon; Trull Silvestre, José Francisco (2020-01-03)
      Article
      Accés obert
      We report comparative experimental and theoretical studies of the second and third harmonic generation from a 20 nm-thick indium tin oxide layer in proximity of the epsilon-near-zero condition. Using a tunable optical ...
