Capturing magic angles in twisted bilayer graphene from information theory markers Calixto Molina, Manuel Mayorgas Reyes, Alberto Castaños, Octavio We thank the support of Spanish MICIU through the project PID2022-138144NB-I00. AM thanks the Spanish MIU for the predoctoral grant FPU19/06376 at the University of Granada in the early stages of this work, and also thanks the Polytechnic University of Cartagena, Spain for a contract under the European Commission project C-QuENS (ID: 101135359). OC was on sabbatical leave at Granada University, Spain, from September 2023 to August 2024. OC thanks support from the program PASPA from DGAPA-UNAM. Zero energy eigenstates ψ0(θ) of the twisted bilayer graphene Hamiltonian at the Dirac point show a high sensitivity to the twist angle θ near the magic angles where the effective Fermi velocity vanishes. We use information theory markers, like fidelity-susceptibility and entanglement entropy of the reduced density matrix to the layer sector, to capture this quantum criticality of zero modes at magic twist angles. 2025-05-05T06:35:04Z 2025-05-05T06:35:04Z 2025-04 journal article M.
