      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 ...

    • Beam shaping and aberration correction using a spatial light modulator in ultracold atom experiments 

      Perez Barrera, Ana Maria (Universitat Politècnica de Catalunya, 2022-09-09)
      Master thesis
      Open Access
      Covenantee:   Universitat de Barcelona / Universitat Autònoma de Barcelona
      In this report we create arbitrary intensity patterns and correct optical aberrations using a spatial light modulator (SLM), which are important requirements for ultracold atom experiments. We explore several methods based ...

    • 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 ...
