I will discuss progress in understanding our benzene HHG spectroscopy results, as well as some recent results from Ravi Bhardwaj's group on the similar topic of HHG in aromatic systems:

JC: Bernd: THz induced field emission from nanostructures
In the first part I will summarise how single-cycle THz pulses can be efficiently generated, and I will present corresponding detection schemes. Due to the low photon energies in the meV range, THz radiation is typically understood to be nonionising. However, several groups have recently demonstrated that field emission from nanostructures can be induced by intense THz fields (see e.g. Herink et al., NJP 16, 123005 (2014); Iwaszczuk et al., Optica 2, 116 (2015).). I will present some of these results and discuss the possibility to generate ultrashort electron bunches with very high kinetic energies.
