Hansen Group - Theory of Ultrafast Spectroscopy, Energy and Charge Transfer

The Hansen Group uses quantum transport theory and quantum chemistry to study energy and charge transfer in molecular systems.

Research focus

The group combines quantum transport theory and quantum chemistry to understand how energy and charge move through molecular landscapes.

The research focuses on optical and electronic processes in photosynthesis and solar cells, including:

  • charge transfer
  • charge separation
  • catalysis

The group applies and develops theoretical tools to simulate time-resolved spectroscopy and molecular electronics experiments that can observe these processes.

Projects

Projects in the group are within the following topics:

  • modelling of pump-probe and/or 2D electronic spectroscopy
  • modelling of BODIPY dyes
  • THz spectroscopy of semiconductor nanoparticles in solar cells
  • time-dependent transport in molecular junctions
  • suppression of plasmon resonances in magnetic gold nanoparticles

Projects may involve studies of how chemical functionalities influence conductivity in molecular systems.

Topics include:

  • quantum interference effects in molecular electron transport
  • local heating, dissipation and thermoelectric response of molecules in conducting junctions
  • mapping transport pathways in complex molecular systems
