  1. 1. Micromagnetic study of spin Hall nano-oscillator arrays and their synchronization dynamics

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Ari Sigurdsson; [2020]
    Nyckelord :spintronics; spin Hall nano-oscillators; spin wave; synchronization; micromagnetic modelling.; spinntronik; spinn-Hall nano-oscillatorer; spinn wave; synkronisering; mikromagnetisk modellering.;

    Sammanfattning : Spintronics is the study of electron spins and their utilization in electronic devices. Within this field, spin-based oscillators have shown promise for mi- crowave signal generation as they can operate at high frequencies, are small in scale and are compatible with modern fabrication techniques.

  3. 2. Real-time Entanglement of Auger and XPS-electrons: a preliminary investigation

    Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Philip Johansson; [2019]
    Nyckelord :Entanglement; Auger; Auger decay; photoemission; XPS; ED; exact diagonalization; Physics and Astronomy;

    Sammanfattning : In this work, we employ a semi-classical approach to light matter interaction to describe and char- acterize spin configurations resulting from quantum correlations between electrons created by a photoemission event and by the following Auger decay. The system studied consists of three atomic levels and two continua. LÄS MER

  4. 3. The Dirac Equation for a Particle in a Spherical Box Potential with Application in Bag Modeling

    Kandidat-uppsats, KTH/Teoretisk fysik

    Författare :Emil Blomquist; Trotte Boman; [2015]
    Nyckelord :;

    Sammanfattning : The Dirac equation is a relativistic wave equation and was the first equation to capture spin in relativistic quantum mechanics. Here, the Dirac equation will be derived and solved for a particle in a spherical box potential. LÄS MER
