Helical boundary modes from synthetic spin in a plasmonic lattice
Sang Hyun Park, Michael Sammon, Eugene Mele +1
Artificial lattices have been used as a platform to extend the application of topological physics beyond electronic systems. Here, using the two-dimensional Lieb lattice as a proto…
Spin Torque Generated by Valley Hall Effect in WSe2
D. J. P. de Sousa, M. J. Sammon, Raseong Kim +3
Monolayer transition metal dichalcogenides are promising materials for spintronics due to their robust spin-valley locked valence states, enabling efficient charge-to-spin conversi…
Plasmonic gain in current biased tilted Dirac nodes
Sang Hyun Park, Michael Sammon, Eugene Mele +1
Surface plasmons, which allow extreme confinement of light, suffer from high intrinsic electronic losses. It has been shown that stimulated emission of electrons can transfer energ…
Broadband Focusing of Acoustic Plasmons in Graphene with an Applied Current
Michael Sammon, Dionisios Margetis, E. J. Mele +1
Non-reciprocal plasmons in current-driven, isotropic, and homogenous graphene with proximal metallic gates is theoretically explored. Nearby metallic gates screen the Coulomb inter…
Efficient domain wall motion in asymmetric magnetic tunnel junctions with vertical current flow
S. Liu, D. J. P. de Sousa, M. Sammon +2
In this paper, we study the domain wall motion induced by vertical current flow in asymmetric magnetic tunnel junctions. The domain wall motion in the free layer is mainly dictated…
Isotropically conducting (hidden) quantum Hall stripe phases in a two-dimensional electron gas
Yi Huang, M. Sammon, M. A. Zudov +1
Quantum Hall stripe (QHS) phases, predicted by the Hartree-Fock theory, are manifested in GaAs-based two-dimensional electron gases as giant resistance anisotropies. Here, we predi…
