  1. 1. Ultracold atoms in optical potentials : from noise-induced transport to superfluidity

    Author : Martin Zelan; Claude Dion; Sile Nic Chormaic; Umeå universitet; []
    Keywords : Brownian motors; noise-induced transport; superfluidity; ultracold atoms; optical potentials; optical lattices; laser coooling; fysik; Physics;

    Abstract : In this thesis, both experimental studies and numerical simulations of ultracold atoms in optical potentials are presented in a collection of nine scientific papers. In particular, noise-induced transport in dissipative optical lattices and superfluid properties of Bose-Einstein condensates have been studied. READ MORE

  2. 2. A neutron noise solver based on a discrete ordinates method

    Author : Huaiqian Yi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; diffusion synthetic acceleration; nuclear reactor modelling; deterministic neutron transport methods; neutron noise; convergence analysis; discrete ordinates;

    Abstract : A neutron noise transport modelling tool is presented in this thesis. The simulator allows to determine the static solution of a critical system and the neutron noise induced by a prescribed perturbation of the critical system. The simulator is based on the neutron balance equations in the frequency domain and for two-dimensional systems. READ MORE
