Triplet superconductivity supported by an X high-order Van Hove singularity
Chethan Sanjeevappa, Anirudh Chandrasekaran, Joseph J. Betouras
We study a four-fold symmetric dispersion relation of a quantum material, which exhibits a single high-order Van Hove singularity of X type at the Fermi energy. First, we analy…
Designing Topological High-Order Van Hove Singularities: Twisted Bilayer Kagomé
David T. S. Perkins, Anirudh Chandrasekaran, Joseph J. Betouras
The interplay of high-order Van Hove singularities and topology plays a central role in determining the nature of the electronic correlations governing the phase of a system with u…
On the engineering of higher-order Van Hove singularities in two dimensions
Anirudh Chandrasekaran, Luke C. Rhodes, Edgar Abarca Morales +4
The properties of correlated electron materials are often intricately linked to Van Hove singularities (VHS) in the vicinity of the Fermi energy. The class of these VHS is of great…
Resonant inelastic X-ray scattering in the topological semimetal FeSi
Yao Shen, Anirudh Chandrasekaran, Jennifer Sears +8
The energy spectrum of topological semimetals contains protected degeneracies in reciprocal space that correspond to Weyl, Dirac, or multifold fermionic states. To exploit the unco…
