13 July 2018: What happens when we heat the atomic lattice of a magnet all of a sudden?
Magnets have fascinated humans for several thousand years and enabled the age of digital data storage. They occur in various flavors. Ferrimagnets form the largest class of magnets and consist of two types of atoms. Similar to a compass needle, each atom exhibits a little magnetic moment, also called spin, which arises from the rotation of the atom's electrons about their own axes. In a ferrimagnet, the magnetic moments point in opposite directions for the two types of atoms (see panel A). Thus, the total magnetization is the sum of all magnetic moments of type 1 (M1), blue arrows) and type 2 (M2), green arrows). Due to the opposite direction, the magnitude of the total magnetization is M1-M2. ...more
 
21 June 2018: "Dr. Federico Furch named 2018 OSA Ambassador"
In October of 2017 the Optical Society (OSA) announced the 2018 class of OSA Ambassadors. One member of this class is MBI researcher Dr. Federico Furch, who in the last few years has been responsible for the development of a state-of-the-art 100 kHz OPCPA laser system that is currently being implemented in attosecond experiments. ...more
 
14 June 2018: "Picture of atomic orbitals featured in NOVA/PBS documentary"
Pictures of atomic hydrogen orbitals measured by MBI researchers are featured in a new NOVA/PBS documentary (see link). In the video, it is explained how the two-dimensional wavefunction of a hydrogen atom can be visualized by recording a large number of ionized electrons, one at a time, on a 2-dimensional detector. The results were published in Physical Review Letters in 2013 (see Highlight link MBI website). and voted one of the Top 10 breakthroughs in Physics in 2013 (see Highlight link MBI website). ...more.
 
13 June 2018: Dr. Daniela Rupp will receive the Karl Scheel Prize 2018
The Physical Society of Berlin announced this year's Karl Scheel laureate. We congratulate Dr. Daniela Rupp, who will receive the award on June 22, 2018 at 5 p.m. the Magnus-Haus in Berlin Mitte. ...more.
 
31 May 2018: X-Ray Holography reveals Nano-Patchwork during Phase Transition in Vanadium Dioxide
In the prototypical material VO2, the role of electronic correlation in the phase transition between the insulating and metallic phase have long been debated. Combining spectroscopy and holography with x-rays, an international team of scientists has now observed how tiny patches of different phases evolve during the phase transition. ...more.
 
4 May 2018: Laser-driven electron recollision remembers molecular orbital structure
Scientists from the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI) in Berlin combined state-of-the-art experiments and numerical simulations to test a fundamental assumption underlying strong-field physics. Their results refine our understanding of strong-field processes such as high harmonic generation (HHG) and laser-induced electron diffraction (LIED). The results have been published in "Science Advances". ...more.
 
16 April 2018: Freeing electrons to better trap them
For the first time, researchers from UNIGE and MBI in Berlin have placed an electron in a dual state - neither freed nor bound - thus confirming a hypothesis from the 1970s. ...more.
 
16 April 2018: From insulator to conductor in a flash
A clever combination of novel technologies enables us to study promising materials for the electronics of tomorrow. Over the past decades, computers have become faster and faster and hard disks and storage chips have reached enormous capacities. But this trend cannot continue forever: we are already running up against physical limits that will prevent silicon-based computer technology from attaining any impressive speed gains from this point on. ...more.
 
12 April 2018: Wiggling atoms switch the electric polarization of crystals
Ferroelectric crystals display a macroscopic electric polarization, a superposition of many dipoles at the atomic scale which originate from spatially separated electrons and atomic nuclei. The macroscopic polarization is expected to change when the atoms are set in motion but the connection between polarization and atomic motions has remained unknown. A time-resolved x-ray experiment now elucidates that tiny atomic vibrations shift negative charges over a 1000 times larger distance between atoms and switch the macroscopic polarization on a time scale of a millionth of a millionth of a second....more.
 
9 April 2018: X-ray snapshots of reacting acids and bases - Erik T. J. Nibbering receives an ERC Advanced Grant for groundbreaking basic research
Dr. Erik T. J. Nibbering of the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI) in Berlin receives an Advanced Grant from the European Research Council (ERC). Goal with this prestigious award is to investigate and elucidate the elementary steps of aqueous proton transfer dynamics between acids and bases. The ERC Advanced Grant is endowed with 2.5 million euro and awarded to well-established top researchers in Europe pursuing scientifically excelling projects. ...more.

27 February 2018: A spinning top of light
Short, rotating pulses of light reveal a great deal about the inner structure of materials. An international team of physicists led by Prof. Misha Ivanov of the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI) has now developed a new method for precisely characterising such extremely short light pulses. The research results have been published in Nature Communications. ...more.
 
19 February 2018: C'mon electrons, let's do the twist! Twisting electrons can tell right-handed and left-handed molecules apart.
Identifying right-handed and left-handed molecules is a crucial step for many applications in chemistry and pharmaceutics. An international research team (CELIA-CNRS/INRS/ Berlin Max Born Institute/SOLEIL) has now presented a new original and very sensitive method. The researchers use laser pulses of extremely short duration to excite electrons in molecules into twisting motion, the direction of which reveals the molecules' handedness. The research results appear in Nature Physics. ...more.
 
16 January 2018: Flexibility and arrangement - the interaction of ribonucleic acid and water
Ribonucleic acid (RNA) plays a key role in biochemical processes which occur at the cellular level in a water environment. Mechanisms and dynamics of the interaction between RNA and water were now revealed by vibrational spectroscopy on ultrashort time scales and analyzed by in-depth theory. ...more.
