    Invited Speaker / Conférencier(ère) invité(e)

    Skyrmions are a topologically non-trivial state that has been observed in a number of different magnetic materials, such as the chiral cubic magnets Cu2OSeO3, FeGe, and MnSi. In these non-centrosymmetric systems, competition between the symmetric exchange interaction and Dzyaloshinskii-Moriya interaction results in the formation of non-trivial incommensurate spin textures, such as skyrmions....

  2. 436. Two views of the dynamical conductivity in MnSi
    Laleh Mohtashemi (Simon Fraser University)

    Magnetic North/Magnétisme Nord
    Oral (Non-Student) / Orale (non-étudiant(e))

    I will present terahertz time-domain spectroscopy measurements of the dynamical conductivity of MnSi, and compare them to Fermi liquid theory at low temperatures and low frequencies. I will also describe a new methodology for terahertz time-domain data analysis, developed to perform this comparison, which has higher sensitivity to fit quality than earlier methods. Within the extended Drude...
