Absorption of Transverse Spin Current in Ferromagnetic NiCu: Dominance of Bulk Dephasing over Spin-Flip Scattering
Youngmin Lim, Shuang Wu, David A. Smith +3
In ferromagnetic metals, transverse spin currents are thought to be absorbed via dephasing -- i.e., destructive interference of spins precessing about the strong exchange field. Ye…
Room-Temperature Intrinsic and Extrinsic Damping in Polycrystalline Fe Thin Films
Shuang Wu, David A. Smith, Prabandha Nakarmi +8
We examine room-temperature magnetic relaxation in polycrystalline Fe films. Out-of-plane ferromagnetic resonance (FMR) measurements reveal Gilbert damping parameters of …
Flat band carrier confinement in magic-angle twisted bilayer graphene
Nikhil Tilak, Xinyuan Lai, Shuang Wu +5
Magic angle twisted bilayer graphene has emerged as a powerful platform for studying strongly correlated electron physics, owing to its almost dispersionless low-energy bands and t…
Chern Insulators and Topological Flat-bands in Magic-angle Twisted Bilayer Graphene
Shuang Wu, Zhenyuan Zhang, K. Watanabe +2
Magic-angle twisted bilayer graphene (MA-TBG) exhibits intriguing quantum phase transitions triggered by enhanced electron-electron interactions when its flat-bands are partially f…
Electrostatic Imaging of Encapsulated Graphene
Michael A. Altvater, Shuang Wu, Zhenyuan Zhang +5
Devices made from two dimensional materials such as graphene and transition metal dichalcogenides exhibit remarkable electronic properties of interest to many subdisciplines of nan…
Numerical study of magnetic and pairing correlation in bilayer triangular lattice
Shuang Wu, Jinling Li, Pan Gao +2
By using the determinant Quantum Monte Carlo method, the magnetic and pairing correlation of the NaCoOyHO system are studied within the Hubbard model on a bi…
