The study has been published in <em>Nature Communications<\/em>.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">The work explores how strong electronic correlations behave in fullerene-based molecular solids containing a single \u201chole\u201d in multiorbital electronic states. Using synchrotron X-ray diffraction, neutron scattering, Raman spectroscopy, NMR, X-ray absorption spectroscopy, and first-principles calculations, the team demonstrated that Yb<sub>2<\/sub>CsC<sub>60<\/sub> remains metallic without undergoing a Mott transition.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">The results reveal a remarkable analogy between correlated molecular <em>p<\/em>-electron systems and transition-metal <em>d<\/em>-electron materials, providing new insight into Hund-coupling physics and strongly correlated quantum matter. The newly synthesized orthorhombic fulleride may also open pathways toward discovering unconventional superconductivity in related molecular systems.<\/p>\n\n\n\n<p class=\"eplus-wrapper wp-block-paragraph\">The paper:<br><strong>\u201c<\/strong><a href=\"https:\/\/www.nature.com\/articles\/s41467-026-73095-z?utm_source=rct_congratemailt&amp;utm_medium=email&amp;utm_campaign=oa_20260526&amp;utm_content=10.1038\/s41467-026-73095-z\"><strong>Survival of the metallic state in a single-hole multiband p-orbital molecular system<\/strong><\/a><strong>\u201d<\/strong><br>K.
