Phonon-limited Transport and Fermi Arc Lifetime in Weyl Semimetals
Francesco Buccheri, Alessandro De Martino, Rodrigo G. Pereira +2
Weyl semimetals harbor topological Fermi-arc surface states which determine the nontrivial charge current response to external fields. We here study the quasiparticle decay rate of…
Topological States in Dimerized Quantum-Dot Chains Created by Atom Manipulation
Van Dong Pham, Yi Pan, Steven C. Erwin +3
Topological electronic phases exist in a variety of naturally occurring materials but can also be created artificially. We used a cryogenic scanning tunneling microscope to create…
Spin-voltage-driven efficient terahertz spin currents from the magnetic Weyl semimetals CoMnGa and CoMnAl
Genaro Bierhance, Anastasios Markou, Oliver Gueckstock +7
Magnetic Weyl semimetals are an emerging material class that combines magnetic order and a topologically non-trivial band structure. Here, we study ultrafast optically driven spin…
Nested Fermi surfaces and correlated electronic phases in hole-doped semiconductor quantum wells
Tommy Li, Julian Ingham, Harley D. Scammell
We demonstrate the existence of novel interaction effects in hole-doped semiconductor quantum wells which are connected to dramatic changes in the Fermi surface geometry occurring…
Transition of laser-induced terahertz spin currents from torque- to conduction-electron-mediated transport
Pilar Jiménez-Cavero, Oliver Gueckstock, Lukáš Nádvorník +16
Spin transport is crucial for future spintronic devices operating at bandwidths up to the terahertz (THz) range. In F|N thin-film stacks made of a ferro/ferrimagnetic layer F and a…
Shot-noise measurements of single-atom junctions
Idan Tamir, Verena Caspari, Daniela Rolf +2
Current fluctuations related to the discreteness of charge passing through small constrictions are termed shot noise. This unavoidable noise provides both advantages - being a dire…
