Fermi arc reconstruction at junctions between Weyl semimetals
Vatsal Dwivedi
We analyze junctions between noninteracting fermionic topological phases. A closed-form condition for the existence of localized modes at the interface is derived using the transfe…
Long-wave magnons in a ferromagnetic film
Gang Li, Chen Sun, Thomas Nattermann +1
An asymptotically exact theory of spectrum and transverse distribution of magnetization in long-wave magnons is presented. It is based on exact analytical solution of linearized La…
Charge puddles in the bulk and on the surface of the topological insulator BiSbTeSe studied by scanning tunneling microscopy and optical spectroscopy
T. Knispel, W. Jolie, N. Borgwardt +6
The topological insulator BiSbTeSe corresponds to a compensated semiconductor in which strong Coulomb disorder gives rise to the formation of charge puddles, i.e., local accumu…
Entropy-limited topological protection of skyrmions
J. Wild, T. N. G. Meier, S. Pöllath +11
Magnetic skyrmions are topologically protected whirls that decay through singular magnetic configurations known as Bloch points. We have used Lorentz transmission electron microsco…
Dynamical defects in rotating magnetic skyrmion lattices
S. Pöllath, J. Wild, L. Heinen +9
The chiral magnet CuOSeO hosts a skyrmion lattice, that may be equivalently described as a superposition of plane waves or lattice of particle-like topological objects.…
Gigantic negative magnetoresistance in a disordered topological insulator
Oliver Breunig, Zhiwei Wang, A. A. Taskin +3
With the recent discovery of Weyl semimetals, the phenomenon of negative magnetoresistance (MR) is attracting renewed interest. While small negative MR can occur due to the suppres…
