Dynamically stabilized spin superfluidity in frustrated magnets
Ricardo Zarzuela, Daniel Hill, Jairo Sinova +1
We study the onset of spin superfluidity, namely coherent spin transport mediated by a topological spin texture, in frustrated exchange-dominated magnetic systems, engendered by an…
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…
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…
Spin Analogues of Superconductivity and the Integer Quantum Hall Effect in an Array of Spin Chains
Daniel Hill, Se Kwon Kim, Yaroslav Tserkovnyak
Motivated by the successful idea of using weakly-coupled quantum electronic wires to realize the quantum Hall effects and the quantum spin Hall effects, we theoretically construct…
Mechanical Actuation of Magnetic Domain-Wall Motion
Se Kwon Kim, Daniel Hill, Yaroslav Tserkovnyak
We theoretically study the motion of a magnetic domain wall induced by transverse elastic waves in a one-dimensional magnetic wire, which respects both rotational and translational…
