Giant Spin Transport Anisotropy in Magnetic Topological Insulators
Marc Vila, Aron W. Cummings, Stephan Roche
We report on exceptionally long spin transport and giant spin lifetime anisotropy in the gapped surface states of three-dimensional (3D) magnetic topological insulators (MTIs). We…
Electrical control of spin and valley in spin-orbit coupled graphene multilayers
Taige Wang, Marc Vila, Michael P. Zaletel +1
Electrical control of magnetism has been a major techonogical pursuit of the spintronics community, owing to its far-reaching implications for data storage and transmission. Here,…
Generation and control of non-local chiral currents in graphene superlattices by orbital Hall effect
Juan Salvador-Sánchez, Luis M. Canonico, Ana Pérez-Rodríguez +15
Graphene-based superlattices offer a new materials playground to exploit and control a higher number of electronic degrees of freedom, such as charge, spin, or valley for disruptiv…
Valley-Polarized Quantum Anomalous Hall Phase in Bilayer Graphene with Layer-Dependent Proximity Effects
Marc Vila, Jose H. Garcia, Stephan Roche
Realizations of some topological phases in two-dimensional systems rely on the challenge of jointly incorporating spin-orbit and magnetic exchange interactions. Here, we predict th…
Canted Spin Texture and Quantum Spin Hall Effect in WTe2
Jose H. Garcia, Marc Vila, Chuang-Han Hsu +3
We report an unconventional quantum spin Hall phase in the monolayer T-WTe, which exhibits hitherto unknown features in other topological materials. The low-symmetry…
Low-symmetry topological materials for large charge-to-spin interconversion: The case of transition metal dichalcogenide monolayers
Marc Vila, Chuang-Han Hsu, Jose H. Garcia +5
The spin polarization induced by the spin Hall effect (SHE) in thin films typically points out of the plane. This is rooted on the specific symmetries of traditionally studied syst…
Nonlocal Spin Dynamics in the Crossover from Diffusive to Ballistic Transport
Marc Vila, Jose H. Garcia, Aron W. Cummings +4
Improved fabrication techniques have enabled the possibility of ballistic transport and unprecedented spin manipulation in ultraclean graphene devices. Spin transport in graphene i…
Magnetic proximity in a van der Waals heterostructure of magnetic insulator and graphene
Bogdan Karpiak, Aron W. Cummings, Klaus Zollner +8
Engineering two-dimensional material heterostructures by combining the best of different materials in one ultimate unit can offer a plethora of opportunities in condensed matter ph…
Tunable Circular Dichroism and Valley Polarization in the Modified Haldane Model
Marc Vila, Nguyen Tuan Hung, Stephan Roche +1
We study the polarization dependence of optical absorption for the modified Haldane model, which exhibits antichiral edge modes in presence of sample boundaries and has been argued…
Room temperature spin Hall effect in graphene/MoS van der Waals heterostructures
C. K. Safeer, Josep Ingla-Aynés, Franz Herling +7
Graphene is an excellent material for long distance spin transport but allows little spin manipulation. Transition metal dichalcogenides imprint their strong spin-orbit coupling in…
Spin transport in graphene/transition metal dichalcogenide heterostructures
Jose H. Garcia, Marc Vila, Aron W. Cummings +1
Since its discovery, graphene has been a promising material for spintronics: its low spin-orbit coupling, negligible hyperfine interaction, and high electron mobility are obvious a…
