  1. 1. Self-consistent dielectric formalism scheme for the paramagnetic electron gas under warm dense matter conditions

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Fotios Kalkavouras; [2022]
    Keywords : Warm Dense Matter WDM ; Quantum One-Component plasmas qOCP ; Vashishta-Singwi VS ; Dielectric Formalism;

    Abstract : The present thesis aims to further a somewhat unexplored area of Warm Dense Matter (WDM) physics through the use of tools developed within the dielectric formalism. WDM is an exotic form of matter with densities close to the solid state and temperatures of several eV. READ MORE

  3. 2. Quantum kinetic relativistic theory of linearized waves in magnetized plasmas

    University essay from Umeå universitet/Institutionen för fysik

    Author : Haidar Al-Naseri; [2018]
    Keywords : Kinetic theory;

    Abstract : In this work we have studied linear wave propagation in magnetized plasmas using a fully relativistic kinetic equation of spin-1/2 particles in the long scale approximation. The linearized kinetic equation is very long and complicated, hence we worked with restricted geometries in order to simplify the calculations. READ MORE

  4. 3. Measurements of electric fields in a plasma by Stark mixing induced Lyman-α radiation

    University essay from Institutionen för fysik och astronomi

    Author : Petter Ström; [2013]
    Keywords : Plasma diagnostic; electric field measurement; non-intrusive; Stark effect; Lyman-alpha; hyperfine structure; H 2s ; cesium vapour;

    Abstract : This paper treats a non-intrusive method of measuring electric fields in plasmas and other sensitive or hostile environments. The method is based on the use of an atomic hydrogen beam prepared in the metastable fine structure quantum state 2s1/2. READ MORE

  5. 4. Contribution from Spin-Orbit Coupling to the Langmuir Wave Dispersion Relation in Magnetized Plasmas

    University essay from Institutionen för fysik

    Author : Petter Johansson; [2010]
    Keywords : Quantum Plasmas; Langmuir Waves; Spin-Orbit Coupling; Magnetized Plasmas;

    Abstract : This thesis analyses the effect spin-orbit coupling has on the dispersion of Langmuir waves in magnetized plasmas, using recently developed kinetic theories of plasmas including quantummechanical and relativistic effects. Two new wave modes appearclose to the resonance  = ( g/2 − 1) , where  is the cyclotron frequency and g is the electron gyromagnetic ratio. READ MORE
