  1. 1. Coulomb drag in parallel nanowires

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : David Dai; [2020]
    Keywords : Coulomb drag; nanowire; Physics and Astronomy;

    Abstract : In this project the transport phenomenon Coulomb drag is studied in a 1D system comprised of two nanowires in parallel. Specifically, a driving current across the active wire generated a drag current in the passive wire, and we studied how Coulomb drag influenced both the driving and drag currents. READ MORE

  2. 2. Development of PSC detection tools using IRF lidar data

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Oriol Peláez Mercadal; [2020]
    Keywords : atmospheric science; polar stratospheric clouds; lidar; data analysis;

    Abstract : Polar stratospheric clouds (PSCs) play a crucial role in ozone depletion mechanisms. Thus, their observations are important to understand their formation processes and active effects towards the atmosphere. READ MORE

  3. 3. Ensemble Green's Function Theory for Interacting Electrons with Degenerate Ground States

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Erik Linnér; [2019]
    Keywords : Green s function; Degeneracy; Density matrix; Ensemble; GW; Zero-temperature; Finite-temperature; Hubbard model; Two-dimensional harmonic oscillator; Ising model; Hydrogen-like model; Physics and Astronomy;

    Abstract : An ensemble Green's function theory for many-electron systems with degenerate ground states, based on the von Neumann density matrix formalism, is proposed. The formalism is constructed without an assumption of an adiabatic connection. An ensemble analogue of Hedin's equations and the GW Approximation (GWA) is constructed. READ MORE

  4. 4. A Fabry–Pérot Cavity for Rare-Earth-Ion-Doped Nanocrystals

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Andre Nüsslein; [2019]
    Keywords : Quantum Computer; Rear Earth Ions; Cavity; Laser; Cavity Quantum Electrodynamics; QED; Solidworks; Physics and Astronomy;

    Abstract : This thesis work contributes to the effort of detecting single rare earth ions doped into crystals, an operation crucial for the development of rare earth quantum computer hardware. Doping crystals with rare earth elements, their trivalent ions substitute some of the crystal’s original bonds. READ MORE

  5. 5. Studies of Light Hyperon Decay Parameters

    University essay from Uppsala universitet/Kärnfysik

    Author : Annele Heikkilä; [2019]
    Keywords : Hadron Physics; Hyperon; CP symmetry; Monte Carlo simulations; BESIII;

    Abstract : A basic assumption in fundamental physics is that equal amounts of matter and antimatter were created after the Big Bang. When particles and antiparticles collide, they annihilate, i.e. disappear and produce photons. READ MORE
