      Treball Final de Grau
      Accés obert
      Realitzat a/amb:   Università degli studi di Trento
      The main objective of this project is to find the binding energy of an impurity interacting with a one-dimensional bosonic system of increasing size for different coupling strengths g. Both the bosons as well as the impurity ...

    • Path Integral Monte Carlo and Bose-Einstein condensation in quantum fluids and solids 

      Rota, Riccardo (Universitat Politècnica de Catalunya, 2011-12-20)
      Tesi
      Accés obert
      Several microscopic theories point out that Bose-Einstein condensation (BEC), i.e., a macroscopic occupation of the lowest energy single particle state in many-boson systems, may appear also in quantum fluids and solids ...

    • Path integral Monte Carlo. Algorithms and applications to quantum fluids 

      Brualla Barberà, Llorenç (Universitat Politècnica de Catalunya, 2002-07-11)
      Tesi
      Accés obert
      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 ...

      Boya Pimentel, Aurelio (Universitat Politècnica de Catalunya, 2010-06-17)
      Projecte Final de Màster Oficial
      Accés obert
      En este trabajo se ha investigado la influencia de la adición de tierras raras sobre la transición de fase y las propiedades dieléctricas del titanato circonato de bario, Ba(ZrxTi1-x)O3 (BZT). Las muestras fueron obtenidas ...

    • Quantum annealing: near future applications 

      Escolano Rubio, Oscar (Universitat Politècnica de Catalunya, 2020-11)
      Treball Final de Grau
      Accés obert
      Introduction to quantum computing with a description of the current state-of-the-art. The practical part consists in a qubit simulation with Rabi cycles under continuous measurements.

    • Quantum Many-Body Systems in 1D: One Dimensional Hydrogen 

      Vidal Arias, Alfredo José (Universitat Politècnica de Catalunya, 2015-06-22)
      Treball Final de Grau
      Accés obert
      The ground-state properties of one-dimensional spin polarized hydrogen, deuterium and tritium at zero temperature are obtained by means of Diffusion Monte Carlo calculations (DMC). The equations of state of the three ...

    • Quantum Monte Carlo study of few-and many-body bose systems in one and two dimensions
