Layer-Dependent Orbital Magnetization in Graphene-Haldane Heterostructures
Sovan Ghosh, Bheema Lingam Chittari
Rhombohedral multilayer graphene (RMG) proximity-coupled to a Haldane substrate provides a platform to investigate the interplay between band topology, layer number, and electric-f…
Gate and Carriers tunable Valley Imbalance in Topological Proximitized Rhombohedral Trilayer Graphene
Sovan Ghosh, Bheema Lingam Chittari
We investigated the electronic structure, Fermi surface topology and the emergence of valley imbalance in rhombohedral trilayer graphene (RTG) induced by the topological proximity…
Topological properties of nearly flat bands in bilayer lattice
Puspita Parui, Sovan Ghosh, Bheema Lingam Chittari
We study the effect of Haldane flux in the bilayer - lattice system, considering possible non-equivalent, commensurate stacking configurations with a tight-bindin…
Orbital Hall Conductivity in a Graphene/Haldane and Haldane/Haldane Bilayers
Sovan Ghosh, Bheema Lingam Chittari
We investigate the orbital Hall conductivity in bilayer graphene (G/G) by modifying one or both the layers as Haldane type ( : Graphene/Haldane and $\rm \tilde G/…
