Equilibrium current in a Weyl-semimetal - superconductor heterostructure
Kevin A. Madsen, Piet W. Brouwer, Maxim Breitkreiz
A heterostructure consisting of a magnetic Weyl semimetal and a conventional superconductor exhibits an equilibrium current parallel to the superconductor interface and perpendicul…
Interference effects induced by a precessing easy-plane magnet coupled to a helical edge state
Kevin A. Madsen, Piet W. Brouwer, Patrik Recher +1
The interaction of a magnetic insulator with the helical electronic edge of a two-dimensional topological insulator has been shown to lead to many interesting phenomena. One of the…
Quantitative analytical theory for disordered nodal points [Article and Erratum]
Björn Sbierski, Kevin A. Madsen, Piet W. Brouwer +1
Disorder effects are especially pronounced around nodal points in linearly dispersing bandstructures as present in graphene or Weyl semimetals. Despite the enormous experimental an…
Josephson effect in a Weyl SNS junction
Kevin A. Madsen, Emil J. Bergholtz, Piet W. Brouwer
We calculate the Josephson current density j(phi) for a Weyl superconductor--normal-metal--superconductor junction for which the outer terminals are superconducting Weyl metals and…
Topological equivalence of crystal and quasicrystal band structures
Kevin A. Madsen, Emil J. Bergholtz, Piet W. Brouwer
A number of recent articles have reported the existence of topologically non-trivial states and associated end states in one-dimensional incommensurate lattice models that would us…
