- Modelling the molecular architecture
Searching for new substances and developing new techniques in the chemical industry: tasks that are often accelerated using computer simulations of molecules or reactions. But even supercomputers q... - Direct Observation of Giant Molecules
Physicists at the Max Planck Institute for Quantum Optics (MPQ) achieved to form giant diatomic molecules and optically detect them afterwards by using a high-resolution objective. The tiny size... - Snapshots of carbon molecules C60
When carbon molecules C60 are exposed to an intense infrared light, they change their ball-like structure to a more elongated version. This has now been observed via laser-induced electron diffrac... - Deterministic creation of entangled atom-light Schrödinger-cat states
In 1935 Erwin Schrödinger formulated a thought experiment designed to capture the paradoxical nature of quantum physics. The crucial element of this gedanken experiment is a cat that is simultaneou...
- Measuring the precise duration of the photoelectric response for the first time
Modern global networks of communication, solar power generation and distribution, and materials science are ultimately based on the photoelectric effect. More than a century after Albert Einstein e...
- The deuteron is smaller than previously thought
The deuteron - one of the simplest atomic nuclei, consisting of just one proton and one neutron - is considerably smaller than previously thought. This finding was arrived at by an international re... - Mapping electromagnetic waveforms
Temporally varying electromagnetic fields are the driving force behind the whole of electronics. Their polarities can change at mind-bogglingly fast rates, and it is difficult to capture them in ac... - Measuring system for light waves in the near-infrared range developed
Those who want to explore the microcosm need exact control over laser light. Only with its help is it possible to explore electron motion and to influence their behavior. Now, scientists at the Lab...
- Laser-based molecular fingerprinting
Scientists often need to detect and measure levels of specific substances in a sea of irrelevant molecules, and infrared light offers an ideal tool for this task. Infrared radiation is invisible to... - A novel microscope for nanosystems
Nanomaterials play an essential role in many areas of daily life. There is thus a large interest to gain detailed knowledge about their optical and electronic properties. Conventional microscopes g... - A novel source of X-rays for imaging purposes
Physicists at LMU Munich and the Max Planck Institute of Quantum Optics have validated a novel laser-driven means of generating bright and highly energetic X-ray beams. The method opens up new ways...
- Characterization of X-ray flashes opens new perspectives in X-ray science
Ultra-short and extremely strong X-ray flashes, as produced by free-electron lasers, are opening the door to a hitherto unknown world. Scientists are using these flashes to take "snapshots" of the ... - Light waves allow preferred bond breaking in symmetric molecules
An international team of scientists discovered a new quantum control mechanism to selectively shake and break C-H bonds in symmetric hydrocarbon molecules with the waveform of femtosecond laser pul... - Scientists record broad absorption spectra on a microsecond scale with two laser frequency combs
A team of scientists around Dr. Nathalie Picqué and Prof. Theodor W. Hänsch at the Laser Spectroscopy Division of the Max Planck Institute of Quantum Optics (Garching), in a collaboration with the ... - Stopping Molecules with a Centrifuge
Does the electron possess an electric dipole moment? Will it be possible to achieve perfect control over chemical reactions between polyatomic molecules, or can one envisage quantum simulations and...
- Watching the heart beat of molecules
MPQ-scientists achieve rapid identification of complex molecules by applying coherent Raman spectroscopy with two laser frequency combs. A team of scientists around Prof. Theodor W. Hänsch and D... - Dr. Nathalie Picqué receives the Coblentz Award
The Coblentz Society has elected Dr. Nathalie Picqué as this year's recipient of the Coblentz Award. Dr. Picqué is currently on long-term leave at the Max-Planck-Institute of Quantum Optics (Garchi... - Frequency combs for sniffing molecules
Most molecules, including those of importance in medical diagnostics or pollution monitoring, have characteristic "fingerprints" in the mid-infrared spectral region. However, state-of-the-art mid-i...
- With single laser pulses on single molecules
Nowadays, large laser systems provide ultra-short light pulses of very high intensity which - in principle - allow the imaging of matter and its dynamics on atomic scales, down to a single molecule...

Scientists at the Max Planck Institute of Quantum Optics achieve direct imaging of quantum fluctuations at absolute zero temperature.Fluctuations are fundamental to many physical phenomena in our e... - Professor Matthias Kling receives Röntgen Prize 2011
Professor Matthias Kling, leader of the "Attosecond Imaging" Research Group at the Max Planck Institute of Quantum Optics, Garching (near Munich), has received this year's Röntgen Prize from the Ju... - A Quantum Pen for Single Atoms
Physicists at the Max Planck Institute of Quantum Optics succeeded in manipulating atoms individually in a lattice of light and in arranging them in arbitrary patterns. These results are an importa...
- International team of researchers observes unexpectedly small proton radius in a precision laser experiment with exotic hydrogen atoms
The proton - one of the universal building-blocks of all matter - is even smaller than had previously been assumed (Nature, 8 July 2010). This is the result obtained at the Paul-Scherrer-Institut (...
