Polar molecules in femto- and attosecond pulses

Prof. Dr. Lars B. Madsen

(Lundbeck Foundation Theoretical Center for Quantum System Research, University of Aarhus,  Denmark)


The large class of polar molecules is interesting for controlled
studies with new light sources. The permanent dipole of the molecule
allows it to be oriented in space with the molecular axes  being fixed  
with respect to the laboratory fixed frame.  In the talk, I will  
discuss molecular frame photoelectron angular distributions, and high-
order harmonic spectra obtained from polar molecules. In the end of  
the talk, I will discuss how the presence of a permanent dipole  
affects time-resolved measurements on the attosecond timescale.
