Altermagnetism from the viewpoint of chemistry
Nayana Devaraj, Anumita Bose, Md Afsar Reja +2
Magnetism has been a central theme of research in chemistry, physics, and materials science, with chemical composition and bonding playing key roles in determining magnetic behavio…
The Bott Metric: A Real-Space Bridge Between Topology and Quantum Metric
Kaustav Chatterjee, Ronika Sarkar, Md Afsar Reja +1
The Bott index has become an indispensable tool to probe the topology of quantum matter, particularly in systems lacking translational symmetry. Constructed from a plaquette operat…
Hexagonal Warping Control of Exceptional Points in Topological Insulator--Ferromagnetic Heterojunctions
Md Afsar Reja, Awadhesh Narayan
Exceptional points (EPs) are non-Hermitian degeneracies, where both eigenvalues and eigenvectors coalesce, which are fundamentally distinct from their Hermitian counterparts. In th…
