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.
The workshop in northern Spain, organised by the New York City Center on Non-Equilibrium Quantum Phenomena, provided the perfect forum to discuss some key questions for the quantum science era.
The multiferroic NiI2 has greater magnetoelectric coupling than any known material of its kind, making it a prime candidate for technology advances, an international research team reports in Nature.
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.
A theory team from the MPSD collaborating with researchers in the United States and Switzerland has explained the key mechanism leading to terahertz amplification in the excitonic insulator candidate Ta2NiSe5. The work has been published in Nature Communications.
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”.
Fangzhou Zhao from the MPSD’s Theory group has been selected for a Humboldt Research Fellowship for postdocs. He will pursue first-principles calculation methods to investigate the light-matter interaction of 2D materials in optical cavities.
Mark Kamper Svendsen has been awarded a Humboldt Research Fellowship to investigate how cavities need to be adapted in order to achieve specific changes in the materials placed inside them.
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 University of California San Diego and the MPSD have used an advanced optical technique to learn more about Ta2NiSe5 (TNS), with a broadened range of frequencies. The MPSD’s Theory Group provided DFT calculations for the study.
Jonathan Mannouch, a postdoc in the Theory Department, has been awarded a Humboldt Research Fellowship. He joined the MPSD in October 2022 and has been developing new approaches for simulating nonadiabatic dynamics in chemical systems.
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.
