Fast gold  
A new mechanism in laser-plasma acceleration has been discovered for heavy ions, which causes a significant increase in kinetic ion energy by means of the Coulomb explosion.  
The inspiring story of helium atoms in strong laser fields  
Surprisingly, the interaction of high-intensity laser radiation with atoms does not necessarily lead to ionization, but can also leave the atoms in excited states. A new study by H. Zimmermann et al.…  
Classic or not? Physics of Nanoplasmas  
The interaction of intense laser pulses with particles on a nanometer scale results in the generation of an expanding nanoplasm. In the past, the dynamics of a nanoplasm was typically described by…  
New insights into the photophysics of the DNA base thymine  
DNA stores our genetic code. Solar UV radiation is sufficiently high energy to break bonds in the DNA and thus cause DNA damage. However, even though DNA (eg in our skin cells) is exposed to intense…  
A nonlinear resonance catastrophe in the light of ultrashort pulses  
Ultra-short light pulses from modern lasers allow the temporal resolution of even the fastest processes in molecules or solid-state materials. For example, after optical excitation, chemical…  
Film chemistry in real time with the high-speed x-ray camera  
Chemistry is omnipresent. In chemical reactions, atoms are deposited in or between molecules while chemical bonds are formed and broken. These chemical bonds consist of valence…  
The longer the better: Long-wave light pulses produce brilliant ultra-short, hard X-ray flashes  
Scientists from the Max Born Institute and the Vienna University of Technology present a new, compact laboratory source for ultra-short, hard X-ray pulses with unprecedented photon flux.  
Am I there, I'm gone ...  
New experiments with helium atoms make it possible to switch the electron correlation on and off as desired.  
Freedom of electrons only lasts for a short time  
During the interaction of an intense extreme ultraviolet (XUV) laser pulse with a cluster, many ions and free electrons are generated, resulting in the formation of a plasma on the nanometer scale.…  
AC/DC for terahertz waves - rectification in picosecond cycle  
Researchers at the Max Born Institute in Berlin are discovering an ultrafast rectifier for terahertz radiation. In the unit cells of a lithium niobate crystal, ac currents are converted to direct…
