Spinor formulation of the Landau-Lifshitz-Gilbert equation with geometric algebra
Kristjan O. Klausen, Snorri Ingvarsson
The Landau-Lifshitz-Gilbert equation for magnetization dynamics is recast into spinor form using the real-valued Clifford algebra (geometric algebra) of three-space. We show how th…
Effect of Impurities on Charge and Heat Transport in Tubular Nanowires
Hadi Rezaie Heris, Kristjan Ottar Klausen, Anna Sitek +2
We calculate the charge and heat currents carried by electrons, originating from a temperature gradient and a chemical potential difference between the two ends of tubular nanowire…
Flux-periodic oscillations in proximitized core-shell nanowires
Kristjan Ottar Klausen, Anna Sitek, Sigurdur I. Erlingsson +1
Flux-periodic oscillations of the superconducting gap in proximitized core-shell nanowires are explored. Periodicity of oscillations in the energy spectrum of a cylindrical nanowir…
Visualizing Stokes' theorem with Geometric Algebra
Kristjan Ottar Klausen
Foundational cases of the generalized Stokes' theorem are visualized using geometric algebra. From considering bivector valued fields, two seldom used instances of the theorem are…
Electron-hole coherence in core-shell nanowires with partial proximity induced superconductivity
Kristjan Ottar Klausen, Anna Sitek, Sigurdur I. Erlingsson +1
By solving the Bogoliubov-de Gennes Hamiltonian, the electron-hole coherence within a partially proximitized n-doped semiconductor shell of a core-shell nanowire heterostructure is…
Electromagnetic field emitted by core-shell semiconductor nanowires driven by an alternating current
Miguel Urbaneja Torres, Kristjan Ottar Klausen, Anna Sitek +3
We consider tubular nanowires with a polygonal cross-section. In this geometry the lowest energy states are separated in two sets, one of corner and one of side-localized states, r…
