  1. 1. Quantum Compactons in an extended Bose-Hubbard model

    University essay from Institutionen för fysik, kemi och biologi

    Author : Peter Jason; [2011]
    Keywords : Bose-Hubbard model; extended Bose-Hubbard model; compactons; quantum compactons;

    Abstract : The Bose-Hubbard model is used to study bosons in optical lattices. In this thesis we will use an extended Bose-Hubbard model to study a type of completely localized solutions, called compactons. The compactons are a special case of the much studied solitons. The soliton is a familiar concept in non-linear physics. READ MORE

  3. 2. Comparison of classical and quantum properties in an extended Bose-Hubbard model

    University essay from Teoretisk Fysik

    Author : Albaro Vega Gutierrez de Pineres; [2011]
    Keywords : bose-hubbard model; extended bose-hubbard model;

    Abstract : In order to explore a quantum version of a discrete nonlinear Schrödinger equation (DNLS), we quantize one nonlinear Schrödinger model, which is used to study different physical systems, e.g. coupled Bose-Einstein condensates. We will focus on small systems, like Dimer and Trimer. READ MORE
