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…
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…
Topological flat bands and higher-order topology in square-octagon lattice
Amrita Mukherjee, Bahadur Singh
Extensive recent research on Lieb and kagome lattices highlights their unique physics characterized by the coexistence of Dirac points, van Hove singularities, and flat bands. In t…
