Strong Field Theory Group

Shaping, controlling and imaging quantum matter with strong laser fields.

Main research directions

  • Ultrafast chirality
  • High Harmonic Spectroscopy
  • Spin-polarization and spin-resolved processes in strong fields
  • Strong field response of quantum materials
  • Our goals

  • Explore opportunities offered by ubiquitous nature of sub-laser cycle response to strong IR fields for shaping, controlling and imaging quantum matter.
  • Understand the link between topological and chiral dynamical phenomena.
  • Create new concepts for shaping, controlling, and imaging of “oriented” media: media with orbital momentum, spin, handedness.
  • Scientific highlights

  • Freeing electrons to better trap them [see 1, 2, 3]
  • From insulator to conductor in a flash [see 1, 2].
  • A spinning top of light [see 1, 2].
  • C'mon electrons, let's do the twist! Twisting electrons can tell right-handed and left-handed molecules apart [see 1, 2].
  • Ultrafast preparation and detection of ring currents in single atoms [see 1]
  • Spin polarization by strong field ionization [see 1, 2]
  • Probing molecular chirality on a sub-femtosecond timescale [see 1,2,3]
  • Ascertaining tunneling time [see 1,2,3].
