  • Quantum phase transitions of a Bose-Einstein condensate 

    Queraltó Isach, Gerard (Universitat Politècnica de Catalunya / Universitat Autònoma de Barcelona, 2015-09-10)
    Master thesis
    Open Access
    Bose-Einstein condensates display quantum phase transitions that cannot be explained with a mean field theory. Describing each trap as an effective site of a Bose-Hubbard model and using the Schwinger representation the ...
