Abstract Arising from the extreme/saddle point in electronic bands. Van Hove singularity (VHS) manifests divergent density of states (DOS) and induces various new states of matter such as unconventional superconductivity. VHS is believed to exist in one and two dimensions. but rarely found in three dimension (3D). https://www.remtavares.com/limited-find-Interstella-Sequin-Long-Sleeve-Mini-Dress-Black-huge-savings/
