Understanding these properties is therefore key,\u201d adds the researcher. \u201cTo measure the characteristic of electron winding, an experimental technique was employed that relies on a synchrotron light source. In this case, measurements were conducted at Elettra Sincrotrone Trieste. Synergy with theoretical analysis and the use of powerful supercomputers was also key: theoretical simulations made it possible to guide the experiments to the specific area of the material in which the properties being studied manifest\u201d.<\/p>\n<p>Rome, 12 June 2023<\/p>\n<p><strong>Image caption:\u00a0<\/strong>Three perspectives of the surface on which electrons move, the Fermi surface.
