Transition from photon absorption to light field-driven dynamics in graphene – paper in NJP
Recently, the coherent manipulation and control of electron trajectories in condensed matter systems with the aid of tailored electric fields has attracted particular attention. Studying this coherent response of electrons using controlled optical waveforms allows for investigating electric properties in solid state systems at optical frequencies. We have recently demonstrated that graphene, a 2-dimensional semi-metallic […]Recently, the coherent manipulation and control of electron trajectories in condensed matter systems with the aid of tailored electric fields has attracted particular attention.

Manuscript on new structures for dielectric laser acceleration published in Optics Letters
In our recent publication in Optics Letters, we show how a dielectric laser accelerator (DLA) can be more efficient. Our silicon dual-pillar structures equipped with a distributed Bragg reflector (DBR) can accelerate electrons 57% more than their counterparts without a DBR. This improvement in acceleration efficiency is achieved by placing an on-chip DBR on one […]

Film and journal article on ACHIP, the particle accelerator on a chip program
A nice article on ACHIP has been published in the DESY research magazine. Issue 1/2019 is dedicated to the plasma acceleration of charged particles. Since the dielectric laser acceleration is related, our scientific progress towards a particle accelerator on a chip is also shown there, see p. 29 here (pdf, 4.4 MB). A film about […]
