Mesógenos alquiloxicianobifenilos : aspectos teóricos y experimentales en las transiciones de fase SmA-N y N-I 

    Cusmin, Paul (Date of defense: 2009-03-11)

    The work presented here has been focused, basically, on the study of the SmA-N and N-I phase transitions of a group of liquid crystals, the alkyloxycyanobiphenyls (nOCB), in which, for some of them, as it is the case of ...

    Path integral Monte Carlo. Algorithms and applications to quantum fluids 

    Brualla Barberà, Llorenç (Date of defense: 2002-07-11)

    Path integral Monte Carlo (PIMC) is a method suitable for quantum liquid simulations at finite temperature. We present in this thesis a study of PIMC dealing with the theory and algorithms related to it, and then two ...
