Higher-Order Van Hove Singularities in Kagome Topological Bands
Edrick Wang, Lakshmi Pullasseri, Luiz H. Santos
Motivated by the growing interest in band structures featuring higher-order Van Hove singularities (HOVHS), we investigate a spinless fermion kagome system characterized by nearest…
Chern Bands with Higher-Order Van Hove Singularities on Topological Moiré Surface States
Lakshmi Pullasseri, Luiz H. Santos
In two-dimensional electronic lattices, changes in the topology of the Fermi surface (Lifshitz transitions) lead to Van Hove singularities characterized by a divergence in the elec…
Quantum Fractality on the Surface of Topological Insulators
Lakshmi Pullasseri, Daniel Shaffer, Luiz H. Santos
Three-dimensional topological insulators support gapless Dirac fermion surface states whose rich topological properties result from the interplay of symmetries and dimensionality.…
Momentum-space Gravity from the Quantum Geometry and Entropy of Bloch Electrons
Tyler B. Smith, Lakshmi Pullasseri, Ajit Srivastava
Quantum geometry is a key quantity that distinguishes electrons in a crystal from those in the vacuum. Its study continues to provide insights into quantum materials, uncovering ne…
