  2. 2. Quantum Few-Body Physics with the Configuration Interaction Approach: Method Development and Application to Physical Systems

    Author : Jonas Cremon; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tonks-Girardeau gas; vortices; Bose-Einstein condensation; quantum many-particle physics; quantum few-particle physics; Lee-Suzuki approximation; configuration interaction method; Wigner localization; quantum dots; ultra-cold gases; Fysicumarkivet A:2010:Cremon;

    Abstract : This dissertation, based on six included papers, theoretically investigates properties of quantum few-particle systems. An overview of related experimental research - ultra-cold trapped dilute gases, and electrons in quantum dots - is given, followed by a description of some of the studied many-particle phenomena - Bose-Einstein condensation, quantized vortices, Wigner localization and the Tonks-Girardeau gas.

  3. 3. Multi-species systems in optical lattices From orbital physics in excited bands to effects of disorder

    University dissertation from Stockholm : Department of Physics, Stockholm University

    Author : Fernanda Pinheiro; Stockholms universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical Physics; teoretisk fysik;

    Abstract : In this thesis we explore different aspects of the physics of multi-species atomic systems in optical lattices. In the first part we will study cold gases in the first and second excited bands of optical lattices - the p and d bands. READ MORE

  4. 4. On time-frequency analysis and pseudo-differential operators for vector-valued functions

    University dissertation from Växjö : Växjö University Press

    Author : Patrik Wahlberg; Växjö universitet.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Abstract : This thesis treats different aspects of time-frequency analysis and pseudodifferential operators, with particular emphasis on techniques involving vector-valued functions and operator-valued symbols. The vector (Banach) space is either motivated by an application as in Paper I, where it is a space of stochastic variables, or is part of a general problem as in Paper II, or arises naturally from problems for scalar-valued operators and function spaces, as in Paper V.

  5. 5. Signal processing approaches on otoacoustic emissions

    University dissertation from Stockholm : Karolinska Institutet, Department of Clinical Neuroscience

    Author : Jun Cheng; Karolinska Institutet.; Karolinska Institutet.; [2000]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; otoacoustic emissions; signal processing; time-frequency representation; cochlea; outer hair cell; neonatal hearing screening; basilar membrane nonlinearity; bounce phenomenon; spectral estimation; interrelations of OAEs;

    Abstract : The recent achievement on the measurement of otoacoustic emissions (OAEs) is based on a novel technical development of digital signal processing. OAEs measured in the external ear canal are normal by-products of the active process in hearing, which was discovered by Kemp (1978). READ MORE
