Spin Stiffness and Domain Walls in Dirac-Electron Mediated Magnets
Sahinur Reja, H. A. Fertig, L. Brey
Spin interactions of magnetic impurities mediated by conduction electrons is one of the most interesting and potentially useful routes to ferromagnetism in condensed matter. In rec…
Spin Response and Collective Modes in Simple Metal Dichalcogenides
Dibya Kanti Mukherjee, Arijit Kundu, H. A. Fertig
Transition metal dichalcogenide (TMD) monolayers are interesting materials in part because of their strong spin-orbit coupling. This leads to intrinsic spin-splitting of opposite s…
Quantum noise detects Floquet topological phases
M. Rodriguez-Vega, H. A. Fertig, B. Seradjeh
We study quantum noise in a nonequilibrium, periodically driven, open system attached to static leads. Using a Floquet Green's function formalism we show, both analytically and num…
