Ultrafast helicity control of surface currents in topological insulators with near-unity fidelity
Christoph Kastl, Christoph Karnetzky, Helmut Karl +1
In recent years, a class of solid state materials, called three-dimensional topological insulators, has emerged. In the bulk, a topological insulator behaves like an ordinary insul…

Ultrafast electronic read-out of diamond NV centers coupled to graphene
Andreas Brenneis, Louis Gaudreau, Max Seifert +6
Nonradiative transfer processes are often regarded as loss channels for an optical emitter1, since they are inherently difficult to be experimentally accessed. Recently, it has bee…

Ion beam synthesis of nanothermochromic diffraction gratings with giant switching contrast at telecom wavelengths
Johannes Zimmer, Achim Wixforth, Helmut Karl +1
Nanothermochromic diffraction gratings based on the metal-insulator transition of are fabricated by site-selective ion beam implantation in a matri…
