Ambarzumyan-type theorem for the Sturm-Liouville operator on the lasso graph

Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Chuan-Fu Yang | Summary: We consider the Sturm-Liouville operator on the lasso graph with a segment and a loop joined at one point, which has arbitrary length. The Ambarzumyan’s theorem for the operator is proved, which says that if the eigenvalues of the operator coincide […]

Linearly dispersive bands at the onset of correlations in K$_x$C$_{60}$ films

Kavli Affiliate: Alessandra Lanzara | First 5 Authors: Ping Ai, Luca Moreschini, Ryo Mori, Drew W. Latzke, Jonathan D. Denlinger | Summary: Molecular crystals are a flexible platform to induce novel electronic phases. Due to the weak forces between molecules, intermolecular distances can be varied over relatively larger ranges than interatomic distances in atomic crystals. […]
