Researchers at the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) have developed an innovative method to study ultrafast magnetism in materials. They have shown the generation and application of magnetic field steps, in which a magnetic field is turned on in a matter of picoseconds.
Chirality is a fundamental property of matter that determines many biological, chemical and physical phenomena. Chiral solids, for example, offer exciting opportunities for catalysis, sensing and optical devices by enabling unique interactions with chiral molecules and polarized light. These properties are however established when the material is…
The renewed funding comes from Columbia University, the Flatiron Institute, the MPSD and the Max Planck Institute for Polymer Research in Mainz, Germany. The New York Center will also expand to include Cornell University as a new partner institution.
Researchers at the MPSD and Brookhaven National Laboratory used two-dimensional terahertz spectroscopy (2DTS) in a non-collinear geometry for the first time to isolate specific terahertz nonlinearities in the cuprate superconductor La1.83Sr0.17CuO4 by their emission direction. Their work has been published in Nature Physics.
Researchers in the Cavalleri group discover that photo-excited YBa2Cu3O6.48, in addition to featuring near zero resistance, also expels a static magnetic field from its interior. Their work has been published in Nature.
Professor Andrea Cavalleri, founding director of the MPSD, is to be honored with the 2024 EPS Europhysics Prize by the European Physical Society. The EPS is awarding the Prize in recognition of his “pioneering studies of photo-induced emergent phases of quantum materials: from enhanced superconductivity to the control of materials topology”.
The MPSD has officially opened its new state-of-the-art research building in Hamburg. The President of the Max Planck Society, Professor Patrick Cramer, and the Second Mayor of the Free and Hanseatic City of Hamburg, Science Senator Katharina Fegebank, were guests of honor at the opening ceremony.
An investigation of the Kagome metal AV3Sb5 without external perturbations has yielded new insights into this group of materials. The work, now published in Nature Physics, is a crucial step in order to understand the intrinsic electronic ground state of this material.
Measurements of the fluctuations of the atomic positions in SrTiO3 under mid-infrared light yield new insights into the creation of the material’s ferroelectric state. An MPSD research team reports in Nature Materials that the material transforms into a state of permanently ordered electrical dipoles.
Researchers at the MPSD have shown that a previously demonstrated ability to turn on superconductivity with a laser beam can be integrated on a chip, opening up a route toward opto-electronic applications.
Researchers from the Cavalleri group have discovered a far more efficient way to create a previously observed metastable, superconducting-like state in K3C60 using laser light. Their work has appeared in Nature Physics.
