Dirac Fermions and Flat Bands in Phosphorus Carbide Nanotubes: Structural and Quantum Phase Transitions in a Quasi-One-Dimensional Material
Shivam Sharma, Chenhaoyue Wang, Hsuan Ming Yu +1
Chemically realistic quasi-one-dimensional (1D) materials in which Dirac fermions and highly degenerate flat bands coexist intrinsically at the Fermi level are exceedingly rare, wh…

Strain-Tunable Topological Phase Transitions in Line- and Split-Graph Flat-Band Lattices
Shivam Sharma, Amartya S. Banerjee
In recent years, materials with topological flat bands have attracted significant attention due to their association with extraordinary transport properties and strongly correlated…
