24th March 2015: Classical or not? Physics of nanoplasmas
The interaction of an intense laser pulse with a nanometer-scale particle results in the generation of an expanding nanoplasma. In the past, nanoplasma dynamics were typically described by classical phenomena, like the thermal emission of electrons. In contrast, a new study on the interaction of intense near-infrared (NIR) laser pulses with molecular oxygen clusters now demonstrates that phenomena, which can only be described quantummechanically, play an important role. ... more.
 
11th February 2015: New Insights into the photophysics of the DNA base thymin
DNA stores our genetic code. Solar UV radiation has sufficiently high energy to basically break bonds of the DNA and thus cause DNA damage. Although DNA (e. g. in our skin cells) is exposed to intense UV light irradiation, DNA proves to be surprising photostable. ... more.
 
10th February 2015: Nonlinear resonance disaster in the light of ultrashort pulses
Ultrashort light pulses from modern lasers enable temporal resolution of even the fastest processes in molecules or solid-state materials. ... more.
