Research Topics

Our research aims to provide a direct, microscopic understanding of the timings of elementary processes in the bulk and at surfaces of solids. To study these processes the time-resolved femtosecond laser spectroscopy and non-linear optics are used, sometimes in combination with sample preparation in ultra-high vacuum.

 

Research focuses on:

  • Femtosecond dynamics of optically excited electrons in molecular adsorbate layers on surfaces, low-dimensional metallic and correlated electron systems studied by time-resolved photoemission.
  • Time-resolved linear and nonlinear optics to (i) analysis of electronic and magnetic properties of solid interfaces (magnetization dynamics, electron-phonon coupling and dynamics of coherent phonons) and (ii) time-resolved vibrational spectroscopy (SFG) of molecules at interfaces.
  • Femtochemistry to surfaces and reaction control by means of intense femtosecond laser pulses to molecules adsorbed on crystal surfaces and metallic nanoparticles.
  • Time-resolved THz spectroscopy for the analysis of low-energy electronic excitations in organic and inorganic solids.
