  2. 1. Correlation Effects in One-dimensional Electron Systems

    Author : Peter Sandström; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; exclusion statistics; resonant tunneling; one dimension; correlated electrons; charge quantization; persistent currents; Aharonov-Bohm effect; Luttinger liquid;

    Abstract : Theoretical studies suggest that an interacting one-dimensional electron system does not behave as a Fermi liquid. Instead, it is predicted to form a Luttinger liquid characterized e.g. by the absence of fermionic quasiparticles and interaction-dependent power-laws for transport quantities. READ MORE

  4. 2. Time-dependent relaxation of charge and energy in electronic nanosystems

    Author : Jens Schulenborg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; heat current; quantum dot; relaxation rate; rate detection; generalization of hermiticity; nonunitary dynamics; open quantum system; Coulomb charging energy; voltage switch; transient response; electronic nanosystem;

    Abstract : The study of the dynamics of strongly confined, interacting open quantum systems has attracted great interest over the past years, due to potential applications in nanoelectronics, metrology as well as quantum information. Most recent experimental and theoretical research in this field has shifted attention towards electronic heat currents, recognizing their potential for practical purposes as well as for tests of fundamental theories, and also aiming to control the inevitable heat dissipation of any dynamically operated electronic device.

  5. 3. Scattering approach to time-dependent charge and energy transport in mesoscopic conductors

    Author : Francesca Battista; Matematisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2013:Battista;

    Abstract : This thesis aims to contribute to the field of time controlled charge and energy transport in mesoscopic systems. In Chapter 1, Chapter 2 and Chapter 3 a short review of the scattering matrix theory is presented, including both charge and energy transport, useful to understand the mathematical landscape used in Papers I, II, III and IV.

  6. 4. Electron Transport in Mesoscopic Semiconductor Nanostructures

    Author : Magnus Persson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis presents results from experimental studies, mostly at very low temperatures, and fabrication of very small electronic components made with GaAs/GaAlAs heterostructures. The components are so small that individual electrons are important to their characteristics. READ MORE

  7. 5. Theoretical studies of collective electronic excitations in low-dimensional structures

    Author : Zhe Yuan; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; linear atomic chains; hydrogen storage; nanodisks; dielectric response; surface plasmon resonances; electron gas model; electronic excitation; metallic thin films; time-dependent density functional theory;

    Abstract : During the past decade, nanoplasmonics and nanophotonicshas emerged as a new branch of nanosciences with many novelapplications. Central in this development is the localized surface plasmon resonance (LSPR) tunable by the sizes and shapes at nanometer scale. READ MORE
