A Nanokelvin Microwave Freezer for Molecules

Researchers at MPQ have developed a novel microwave cooling technique for molecular gases. It enables polar molecules to be cooled down to a few nanokelvin, 21 billionths of a degree above absolute zero. In doing so, they set a new low-temperature record and pave the way for new forms of quantum matter that were previously not experimentally accessible. more

Photographing a light helix

With their newly developed "nanoTIPTOE" technique, physicists from the Max Planck Institute of Quantum Optics and the Ludwig Maximilian University of Munich, in cooperation with Stanford University, have managed for the first time to record a helical light field on shortest time and length scales. more

Digital holography with multiple colours

With the help of special light sources, the three-dimensional shape and spectrum of objects can be recorded completely without photographic lenses. The trick behind is a highly sophisticated form of interference in space and time. more

Topological phase detected in spin chains

In a special arrangement of atomic spins, Max Planck physicists have measured the properties of the so-called Haldane phase in an experiment. To do so, they used a quantum mechanical trick. more

The world’s most powerful dual-comb spectrometer

Scientists from Hamburg and Munich developed the world's most powerful dual-comb spectrometer that paves the way for many applications in atmospheric science and biomedical diagnostics, such as early cancer detection. more

Controlling the Waveform of Ultrashort Infrared Pulses

Laser physicists of the attoworld team at Ludwig Maximilians Universität, the Max Planck Institute of Quantum Optics and the Center for Molecular Fingerprinting have achieved unprecedented control over light pulses in the mid-infrared wavelength range. more

Light-Controlled Reactions at the Nanoscale

Physicists at the Max Planck Institute of Quantum Optics and Ludwig-Maximilians-Universität Munich in collaboration with Stanford University have used for the first time laser light to control the location of light-induced reactions on the surface of nanoparticles. more

Quantum magnets in motion

For the first time, researchers have succeeded in observing a new transport phenomenon in spin chains under the microscope - with surprising results: the movement in the quantum world resembles certain phenomena known from everyday life like the form of coffee stains on a tablecloth. more
