A variety of physical systems, from atoms to solids, can be reduced to two energy bands in their interaction with intense light fields to describe the essential dynamics. In our new paper, we use such a 2-band model to present an intuitive categorization into five different regimes - from the pertub...

In memory of Professor Mark Stockman, an exceptional theoretical physicist and dear colleague, we show in our recent publication that coherent control at nanotips made of the plasmonic material gold can be observed even approaching the strong-field region. In our experiment, photoelectrons are emitt...

In a special issue in memorial of our late colleague Mark Stockman, we compare two methods of light-field control of electric currents in graphene: Control via the carrier-envelope phase (CEP) of a single laser pulse at a central light frequency ω, and 2-color control using laser pulses at central l...

A review article on particle acceleration on a photonic chip by England, Hommelhoff and Byer has appeared in Physics Today, the journal of the American Physical Society. Here is the link to it.
