Spontaneous surface flux pattern in chiral p-wave superconductors - revisited
Sarah B. Etter, Adrien Bouhon, Manfred Sigrist
In chiral -wave superconductors, magnetic flux patterns may appear spontaneously when translational symmetry is broken such as at surfaces, domain walls, or impurities. However,…
Interband interference effects at the edge of a multiband chiral p-wave superconductor
Jia-Long Zhang, Wen Huang, Manfred Sigrist +1
Chiral superconductors support chiral edge modes and potentially spontaneous edge currents at their boundaries. Motivated by the putative multiband chiral p-wave superconductor Sr$…
Evolution of the filamentary 3-Kelvin phase in Pb-Ru-Sr2RuO4 Josephson junctions
Hirono Kaneyasu, Sarah B. Etter, Toru Sakai +1
The evolution of the filamentary 3-Kelvin (3K) superconducting phase at the interface between Sr2RuO4 and Ru-metal inclusions is discussed for Pb-Ru-Sr2RuO4 contacts. Using the Gin…
Surface magnetism in a chiral d-wave superconductor with hexagonal symmetry
Jun Goryo, Yoshiki Imai, W. B. Rui +2
Surface properties are examined in a chiral d-wave superconductor with hexagonal symmetry, whose one-body Hamiltonian possesses the intrinsic spin-orbit coupling identical to the o…
Weyl-type topological phase transitions in fractional quantum Hall like systems
Stefanos Kourtis, Titus Neupert, Christopher Mudry +2
We develop a method to characterize topological phase transitions for strongly correlated Hamiltonians defined on two-dimensional lattices based on the many-body Berry curvature. O…
Theory of in-plane current induced spin torque in metal/ferromagnet bilayers
Kohei Sakanashi, Manfred Sigrist, Wei Chen
Using a semiclassical approach that simultaneously incorporates the spin Hall effect (SHE), spin diffusion, quantum well states, and interface spin-orbit coupling (SOC), we address…
