Chiral magnetism: a geometric perspective
Daniel Hill, Valeriy Slastikov, Oleg Tchernyshyov
We discuss a geometric perspective on chiral ferromagnetism. Much like gravity becomes the effect of spacetime curvature in theory of relativity, the Dzyaloshinski-Moriya interacti…
Edge State Wave Functions from Momentum-Conserving Tunneling Spectroscopy
T. Patlatiuk, C. P. Scheller, D. Hill +7
We perform momentum-conserving tunneling spectroscopy using a GaAs cleaved-edge overgrowth quantum wire to investigate adjacent quantum Hall edge states. We use the lowest five wir…
Self-stabilizing exchange-mediated spin transport
T. Schneider, D. Hill, A. Kákay +9
Long-range spin transport in magnetic systems can be achieved by means of exchange-mediated spin textures with robust topological winding -- a phenomenon referred to as spin superf…
Evolution of the quantum Hall bulk spectrum into chiral edge states
Taras Patlatiuk, Christian P. Scheller, Daniel Hill +6
One of the most intriguing and fundamental properties of topological materials is the correspondence between the conducting edge states and the gapped bulk spectrum. So far, it has…
Easy-Plane Magnetic Strip as a Long Josephson Junction
Daniel Hill, Se Kwon Kim, Yaroslav Tserkovnyak
Spin-torque-biased magnetic dynamics in an easy-plane ferromagnet (EPF) is theoretically studied in the presence of a weak in-plane anisotropy. While this anisotropy spoils U(1) sy…
