Heavy surface state in a possible topological Kondo insulator: Magneto-thermoelectric transport on the (011)-plane of SmB
Yongkang Luo, Hua Chen, Jianhui Dai +2
Motivated by the high sensitivity to Fermi surface topology and scattering mechanisms in magneto-thermoelectric transport, we have measured the thermopower and Nernst effect on the…
Theory of Transport Phenomena in Coherent Quantum Hall Bilayers
I. Sodemann, H. Chen, A. H. MacDonald
We argue that all anomalous transport properties of coherent quantum quantum Hall bilayers can be understood in terms of a mean-field transport theory in which the condensate phase…
Observation of Majorana Fermions in Ferromagnetic Atomic Chains on a Superconductor
Stevan Nadj-Perge, Ilya K. Drozdov, Jian Li +6
Majorana fermions are predicted to localize at the edge of a topological superconductor, a state of matter that can form when a ferromagnetic system is placed in proximity to a con…
Topological Superconductivity induced by Ferromagnetic Metal Chains
Jian Li, Hua Chen, Ilya K. Drozdov +3
Recent experiments have provided evidence that one-dimensional (1D) topological superconductivity can be realized experimentally by placing transition metal atoms that form a ferro…
Non-Local Transport Mediated by Spin-Supercurrents
Hua Chen, Andrew D. Kent, Allan H. MacDonald +1
In thin film ferromagnets with perfect easy-plane anisotropy, the component of total spin perpendicular to the easy plane is a good quantum number and the corresponding spin superc…
Proximity Effects in Topological Insulator Heterostructures
Xiaoguang Li, Gufeng Zhang, Guangfen Wu +3
Topological insulators (TIs) are bulk insulators that possess robust helical conducting states along their interfaces with conventional insulators. A tremendous research effort has…
