Enrico Ronca is awarded an ERC Starting Grant

Former MPSD researcher plans to utilize grant for proposing new techniques based on quantum fields to control magnetic properties of molecules. more

Light and electrons spin together

Theoreticians at the MPSD have demonstrated how the coupling between intense lasers, the motion of electrons, and their spin influences the emission of light on the ultrafast timescale. more

High harmonics show atoms in motion

An MPSD theory team describes in PNAS how high harmonics can illuminate the movement of atoms and electrons down to a few femtoseconds. As the high harmonics change in intensity, they provide ‘snapshots’ of the atoms’ and electrons’ movements at each exact moment. more

Exploiting free-electron lasers for time-domain interferometry and quantum optics

Max Planck Quantum Matter Seminar
  • Date: Nov 10, 2022
  • Time: 04:00 PM - 05:00 PM (Local Time Germany)
  • Speaker: Simon Gerber
  • Paul Scherrer Institute, Switzerland
  • Location: CFEL (Bldg. 99)
  • Room: Seminar Room IV, O1.111
  • Host: Gregor Jotzu
Brilliant, ultrashort, and coherent X-ray free-electron laser pulses allow investigations of dynamics at the inherent time and length scale of atoms. However, missing are sequences of phase-locked X-ray pulses, desirable for time-domain correlation spectroscopies and coherent quantum control. In this seminar, I will present a scheme to generate sub-femtosecond, phase-locked X-ray pulse pairs with up to 100 fs delay. This enables time-domain interferometry, such as the X-ray analog of the ubiquitous Fourier transform infrared spectrometer or resonant inelastic X-ray scattering, and, more generally, all of nonlinear and quantum optics requiring coherent copies of beams.
