Topological index for periodically driven time-reversal invariant 2D systems
David Carpentier, Pierre Delplace, Michel Fruchart +1
We define a new -valued index to characterize the topological properties of periodically driven two dimensional crystals when the time-reversal symmetry is enforced. This inde…
Chiral symmetry and bulk--boundary correspondence in periodically driven one-dimensional systems
J. K. Asboth, B. Tarasinski, P. Delplace
Over the past few years, topological insulators have taken center stage in solid state physics. The desire to tune the topological invariants of the bulk and thus control the numbe…
Proposal for an ac spin current source
Patrick P. Hofer, Hugo Aramberri, Christoph Schenke +1
We propose an ac current source that can be tuned from a pure charge to a pure spin current source. The device consists of two mesoscopic capacitors attached to a two-dimensional s…
