Topological Phases of Noncentrosymmetric Superconductors: Edge States, Majorana Fermions, and the Non-Abelian Statistics
Masatoshi Sato, Satoshi Fujimoto
The existence of edge states and zero energy modes in vortex cores is a hallmark of topologically nontrivial phases realized in various condensed matter systems such as the fractio…
Hall Effect of Spin Waves in Frustrated Magnets
Satoshi Fujimoto
We examine a possible spin Hall effect for localized spin systems with no charge degrees of freedom. In this scenario, a longitudinal magnetic field gradient induces a transverse s…
Topological Order and Non-Abelian Statistics in Noncentrosymmetric s-Wave Superconductors
Satoshi Fujimoto
We demonstrate that in two-dimensional noncentrosymmetric s-wave superconductors under applied magnetic fields for a particular electron density, topological order emerges, and the…
Fractional flux quanta at intrinsic metallic interfaces of noncentrosymmetric superconductors
C. Iniotakis, S. Fujimoto, M. Sigrist
We examine intrinsic interfaces separating crystalline twin domains of opposite spin-orbit coupling in a noncentrosymmetric superconductor such as CePt3Si. At these interfaces, low…
Thermodynamics of impurities in the anisotropic Heisenberg spin-1/2 chain
J. Sirker, S. Fujimoto, N. Laflorencie +2
The thermodynamics of finite open antiferromagnetic XXZ chains is studied using field theory, Bethe Ansatz and quantum Monte Carlo methods. For the susceptibility a parameter-free…
