Type-II Mirror Chern Insulator in Altermagnets
Amrita Mukherjee, Pritesh Srivastava, Rahul Verma +1
Altermagnets with momentum-dependent spin splitting despite zero net magnetization can support unique topological states under broken time-reversal symmetry. We predict a mirror-sy…
Isolation of spin-valley locked nodal-line fermions in -wave altermagnets
Pritesh Srivastava, Rahul Verma, Bahadur Singh
The paper predicts and analyzes spin‑valley‑locked nodal‑line fermions in the d‑wave altermagnet family AV₂X₂O using first‑principles calculations and a minimal tight‑binding model…
Topologically nontrivial flat bands and quantum Hall crossovers in square-octagon lattice materials
Amrita Mukherjee, Rahul Verma, Pritesh Srivastava +1
Coexistence of nontrivial topology and flat electronic bands provides a fertile platform for correlated quantum states. The square-octagon lattice hosts Dirac nodes and flat bands…
Discovery of Quasi One Dimensional Superconductivity in PtPb3Bi
Shashank Srivastava, Yash Vardhan, Anshu Kataria +11
Quasi one dimensional materials provide a compelling platform where reduced dimensionality stabilizes intertwined topological and superconducting phases. Here we report superconduc…
Emergent spin Hall quantization and high-order van Hove singularities in square-octagonal MAZ
Rahul Verma, Yash Vardhan, Hsin Lin +1
Quantum spin Hall (QSH) insulators are versatile platforms for exploring exotic quantum phases, especially when combined with high-order van Hove singularities (VHSs) that enhance…
Theory of Spiral Magnetism in Weyl semimetal SmAlSi
Lasin Thaivalappil, Rahul Verma, Hsin Lin +2
Recent neutron scattering and thermodynamic measurements suggest that Weyl electrons in the emergent Weyl semimetal SmAlSi mediate unconventional magnetic interactions and induce s…
