IIT Kanpur Maps Beating Nodes To Graphene's ...
Researchers at IIT Kanpur and the Indian Institute of Science Bangalore derived scaling relations from Onsager's quantization relation to distinguish the origins of quantum oscillation beating in graphene, showing that a pseudomagnetic field yields Nc,j ∝ (2j+1)Bc,j² while energy splitting yields Nc,j ∝ (2j+1)²Bc,j². The framework gives experimentalists a quantitative tool to identify strain-induced pseudomagnetic fields versus valley- or spin-dependent band splittings in graphene-based systems, directly informing the characterization of graphene materials and devices.
