  • Two-component Bose-Einstein condensates with competing interactions 

    Sanz Sánchez, Julio (Universitat Politècnica de Catalunya, 2020-02-10)
    Doctoral thesis
    Open Access
    This thesis reports the experimental study of two-component Bose-Einstein condensates with tunable interactions, which are exploited as a platform to perform quantum simulation of many-body quantum systems. To perform ...
  • Spectral response of individual molecules and nanoantennas with two-beam excitation 

    Gellings, Esther (Universitat Politècnica de Catalunya, 2020-02-21)
    Doctoral thesis
    Open Access
    At room temperature, individual molecules can be found in different conformations due to intrinsic and extrinsic factors which are reflected in spectral variability. When detecting single molecules, the ensemble average ...
  • Plasmon-electron interactions in low dimensional materials 

    De Vega Esteban, Sandra (Universitat Politècnica de Catalunya, 2020-02-17)
    Doctoral thesis
    Open Access
    Ever since the advent of modern technology, major developments have come hand in hand with miniaturization and speed of operation. A proof of this is provided by the impressive success of Moore's law, which predicted that ...
  • Polaron physics in carbon nanotube electro-mechanical resonators 

    De Bonis, Sergio Lucio (Universitat Politècnica de Catalunya, 2020-02-06)
    Doctoral thesis
    Open Access
    Carbon nanotube (CNT) mechanical resonators are unique systems because they combine remarkable mechanical properties with rich charge transport characteristics. Thanks to their intrinsically low-dimensional nature, their ...
  • Quantum Brownian motion in Bose-Einstein condensates 

    Charalambous, Christos (Universitat Politècnica de Catalunya, 2020-01-31)
    Doctoral thesis
    Open Access
    Quantum Brownian motion is one of the most prominent examples of an open quantum system, a system which cannot be treated in isolation from its environment. The simplest method to study the dynamics of a system undergoing ...
  • Development of a high intensity Mid-Ir OPCPA pumped by a HO:YLF amplifier 

    Sánchez Peacham, Daniel Alexander (Universitat Politècnica de Catalunya, 2020-01-27)
    Doctoral thesis
    Open Access
    The continuous development of laser sources delivering ultra-short light pulses underpins much of the current progress in experimental science, particularly in the domain of physics concerned with strong-field phenomena. ...
  • From cells to tissues, microscopy to modeling: towards precise, data-driven photothermal therapy with gold nanorods 

    Morales Dalmau, Jordi (Universitat Politècnica de Catalunya, 2019-02-15)
    Doctoral thesis
    Open Access
    Suspensions of gold nanorods (GNRs) are emerging as potential drugs to address some of the limitations in traditional biomedical sensing,imaging and therapy. They are inorganic nanoparticles with good biocompatibility, ...
  • Quantifying nanoscale carrier diffusion with ultrafast optical and photocurrent microscopy 

    Block, Alexander (Universitat Politècnica de Catalunya, 2019-09-06)
    Doctoral thesis
    Restricted access - author's decision
    Heat transport in solids is one of the oldest problems in physics, dating back to the earliest formulations of thermodynamics. The classical laws of heat conduction are valid as long as the observed time and length scales ...
  • Quantum information outside quantum information 

    Pozas Kerstjens, Alejandro (Universitat Politècnica de Catalunya, 2019-10-15)
    Doctoral thesis
    Open Access
    Quantum theory, as counter-intuitive as a theory can get, has turned out to make predictions of the physical world that match observations so precisely that it has been described as the most accurate physical theory ever ...
  • Time domain, near-infrared diffuse optical methods for path length resolved, non-invasive measurement of deep-tissue blood flow 

    Pagliazzi, Marco (Universitat Politècnica de Catalunya, 2019-10-04)
    Doctoral thesis
    Open Access
    The non-invasive and, often, continuous measurement of the hemodynamics of the body, and for the main purposes of this thesis, the brain, is desired because both the instantaneous values and their changes over time constantly ...
  • Charge carrier dynamics and interfaces in perovskite solar cells 

    Rueda Delgado, Diana Paola (Universitat Politècnica de Catalunya, 2019-07-30)
    Doctoral thesis
    Open Access
    Covenantee:  Karlsruher Institut für Technologie
    Organometal halide perovskites for solar cells are hybrid semiconductors that recently have caught the attention of the scientific community due to its excellent performance and attractive optical properties. Since then, ...
