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 La_1.83Sr_0.17CuO₄ by their emission direction. Their work has been published in Nature Physics. more

Researchers in the Cavalleri group discover that photo-excited YBa₂Cu₃O_6.48, in addition to featuring near zero resistance, also expels a static magnetic field from its interior. Their work has been published in Nature. more

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”. more

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.  more

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.  more
