      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 ...
    • Viscous regime of electron transport at a graphene constriction 

      Pita Vidal, Marta (Universitat Politècnica de Catalunya, 2017-04)
      Treball Final de Grau
      Accés obert
      Realitzat a/amb:   Massachusetts Institute of Technology
      Under mesoscopic conditions, strong electron-electron interactions and weak electron-phonon coupling in graphene lead to an hydrodynamic behaviour of electron dynamics, resulting in unusual transport phenomena. During the ...
