The Streda Formula for Floquet Systems: Topological Invariants and Quantized Anomalies from Cesaro Summation
Lucila Peralta Gavensky, Gonzalo Usaj, Nathan Goldman
The StÅeda formula establishes a fundamental connection between the topological invariants characterizing the bulk of topological matter and the presence of gapless edge modes. In…

Quantized Chern-Simons Axion Coupling in Anomalous Floquet Systems
Lucila Peralta Gavensky, Nathan Goldman, Gonzalo Usaj
Quantized bulk response functions are hallmark signatures of topological phases, but their manifestation in periodically driven (Floquet) systems is not yet fully established. Here…

Charge and spin transport in nanoscopic structures with spin-orbit coupling
A. A. Reynoso, G. Usaj, C. A. Balseiro
During the last years there has been much interest, and theoretical discussion, about the possibility to use spin-orbit coupling to control the carriers spins in two-dimensional se…
