Steering Majorana braiding via skyrmion-vortex pairs: a scalable platform
Jonas Nothhelfer, Sebastián A. Díaz, Stephan Kessler +4
Majorana zero modes are quasiparticles that hold promise as building blocks for topological quantum computing. However, the litmus test for their detection, the observation of exot…
The 2020 Skyrmionics Roadmap
C. Back, V. Cros, H. Ebert +16
The notion of non-trivial topological winding in condensed matter systems represents a major area of present-day theoretical and experimental research. Magnetic materials offer a v…
Spin eigen-excitations of an antiferromagnetic skyrmion
Volodymyr P. Kravchuk, Olena Gomonay, Denis D. Sheka +5
We theoretically predict and classify the localized modes of a skyrmion in a collinear uniaxial antiferromagnet and discuss how they can be excited. As a central result, we find tw…
Skyrmion production on demand by homogeneous DC currents
Karin Everschor-Sitte, Matthias Sitte, Thierry Valet +2
Topological magnetic textures - like skyrmions - have become a major player in the design of next-generation magnetic storage technology due to their stability and the control of t…
Interaction Correction to the Magneto-Electric Polarizability of Topological Insulators
Karin Everschor-Sitte, Matthias Sitte, Allan H. MacDonald
When time-reversal symmetry is weakly broken and interactions are neglected, the surface of a topological insulator supports a half-quantized Hall conductivity $σ_{S} = e^{…
Real-Space Berry Phases - Skyrmion Soccer
Karin Everschor-Sitte, Matthias Sitte
Berry phases occur when a system adiabatically evolves along a closed curve in parameter space. This tutorial-like article focuses on Berry phases accumulated in real space. In par…
