Local optical control of ferromagnetism and chemical potential in a topological insulator
Andrew L. Yeats, Peter J. Mintun, Yu Pan +4
Many proposed experiments involving topological insulators (TIs) require spatial control over time-reversal symmetry and chemical potential. We demonstrate reconfigurable micron-sc…
Persistent Optical Gating of a Topological Insulator
Andrew L. Yeats, Yu Pan, Anthony Richardella +3
Topological insulators (TIs) have attracted much attention due to their spin-polarized surface and edge states, whose origin in symmetry gives them intriguing quantum-mechanical pr…
Perpendicular Magnetization and Generic Realization of the Ising Model in Artificial Spin Ice
Sheng Zhang, Jie Li, Ian Gilbert +11
We have studied frustrated kagome arrays and unfrustrated honeycomb arrays of magnetostatically-interacting single-domain ferromagnetic islands with magnetization normal to the pla…
