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.
Terahertz light pulses can stabilize ferromagnetism in YTiO3 at temperatures more than three times its usual transition temperature. Researchers from the Cavalleri group report in Nature that the high-temperature ferromagnetic state persisted for many nanoseconds after the light exposure.
How long does it take electrons to ‘dress’ in light and form Floquet bands? Just one single optical cycle is enough, according to a research team involving the Universities of Marburg, Regensburg and MPSD group leader Michael Sentef. Its study has been published in Nature.
Wiebke Kohlbrecher (20) has spent five weeks at the MPSD to learn at first hand about the day-to-day work of its researchers. She will complete three internships in total as part of the Hamburg-based ProTechnicale program which offers female school leavers an orientation year in STEM (Science, Technology, Engineering and Maths) occupations.
Researchers in Germany and the U.S.A. propose a new optical method to verify topological magnon phases. Writing in PRL, the team shows that the intensity of polarized laser light scattered back from a magnetic material is an indicator of topological phases.
Researchers from the Cavalleri group report in PNAS that superconducting ‘stripes’ in certain copper-based compounds may lead to a break in the material’s crystal symmetry, thus resulting in anomalous emission of terahertz radiation.
