Ultrafast molecular chirality: twisting light to twist Electrons – Olga Smirnova receives an ERC Advanced Grant  
ERC Logo orange black white An ERC Advanced Grant has been awarded to Professor Dr. Olga Smirnova of the Max Born Institute and Technische Universität Berlin.  
Persistent swinging of electrons between atomic sites in crystals  
Excerpt of the Graphic: Unit cell of paraelectric KDP. b) Equilibrium electron density map at room temperature, ρ0(r) is shown in the gray plane of a) containing the potassium (K), phosphorous (P), and the two upper oxygen (O) atoms of the phosphate group. Phonons are quantum excitations which correspond to vibrations of the regular atomic array of a crystal. This crystal lattice consists of a large number of unit cells with an identical atomic…  
Accelerating write/erase cycles in all-optical magnetization switching  
Excerpt of Graphic: Ultrafast switching dynamics of a GdFe and GdCo alloy, showing the magnetization as a function of time after the laser pulse Magnetic bits for data storage can be written with ultrafast laser pulses, in contrast to the well-established path of using magnetic fields administered via a write head. Researchers at Max Born…  
An ultrafast X-ray glance into photoacid electronic structure  
Photoacids are molecules that release a proton upon electronic excitation, thus enhancing the acidity of a liquid. Pioneering work by Theodor Förster has shown the direct relationship between the…  
Attosecond pulses: 100 times more  
Excerpt of Attosecond streaking results Graphic 2 Attosecond laser pulses in the extreme ultraviolet (XUV) are a unique tool enabling the observation and control of electron dynamics in atoms, molecules, and solids. Most attosecond laser sources…  
Center stage for quantum mechanical entanglement in an attosecond laser laboratory  
Graphic: Sketch of the experiment. Quantum mechanics is famous for the way that its predictions challenge intuitive human thinking developed through the way that we experience the everyday world around us.  Among other things,…  
Intense monocycle terahertz pulses from shifting electrons in quantum structures  
A time-dependent electric current emits an electromagnetic wave, a basic physical effect exploited in telecom antennas. Transferring this mechanism to the ultrashort length and time scales of the…  
Lorenz Drescher wins the 2021 Carl-Ramsauer Award  
Lorenz Drescher has been awarded one of the 2021 Carl-Ramsauer Awards from the Deutsche Physikalische Gesellschaft zu Berlin (PGzB) for his dissertation entitled „Transient dipole interactions on…  
Ultrafast and coupled – atomic vibrations in the quantum material boron nitride  
Materials consisting of a few atomic layers display properties determined by quantum physics. In a stack of such layers, vibrations of the atoms can be triggered by infrared light. New experimental…  
Thomas Elsaesser receives the Ahmed Zewail Award for Ultrafast Science and Technology from the American Chemical Society  
The American Chemical Society (ACS) has awarded Thomas Elsaesser the Ahmed Zewail Award 2022. The prize is named after Ahmed Zewail, a pioneer of ultrafast science and Nobel Prize winner in…
