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…
