    • An experimental setup for gray molasses sub-Doppler cooling of potassium gases 

      Bosch Aguilera, Manel (Universitat Politècnica de Catalunya, 2014-09-09)
      Master thesis
      Open Access
      [ÀNGLÈS] An experimental setup for cooling a gas of potassium atoms below the Doppler limit is presented. This method is known as gray molasses cooling. It will be implemented using light blue light blue detuned with respect ...
    • Design and construction of optical superlattices for a quantum gas experiment 

      Sastre Pellicer, Jordi (Universitat Politècnica de Catalunya, 2015-10)
      Bachelor thesis
      Open Access
      In recent years ultracold atomic gases have emerged as a new and promising platform for exploring the physics of quantum many-body systems, allowing researchers to revisit fundamental problems of condensed-matter physics ...
    • Development of a fluorescence imaging system for a quantum gas experiment 

      Sanz Sánchez, Julio (Universitat Politècnica de Catalunya, 2015-09-10)
      Master thesis
      Open Access
      Covenantee:   Universitat Autònoma de Barcelona / Institut de Ciències Fotòniques (ICFO) / Universitat de Barcelona
      In this report we present a technique for imaging the momentum distribution of an ultracold atomic gas in 3D and with single atom resolution. We describe the first experimental steps taken to implement it in a quantum gas ...
    • Quantum liquid droplets in a mixture of Bose-Einstein condensates 

      Cabrera Córdova, César Raymundo (Universitat Politècnica de Catalunya, 2018-10-10)
      Doctoral thesis
      Open Access
      In this thesis, we report on the design and construction of a quantum simulator experiment using quantum gases in Spain. This experiment exploits mixtures of the three isotopes of potassium, which give access in an original ...
    • 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 ...
