Microwave Imaging of Edge Conductivity in Graphene at Charge Neutrality and Quantum Hall States
Hongtao Yan, Chun-Chih Tseng, Anzhuoer Li +8
We report local conductivity imaging of edge states in monolayer graphene by millikelvin microwave impedance microscopy (MIM). At the charge-neutrality point, as the magnetic field…

Entanglement entropy as a probe of topological phase transitions
Manish Kumar, Bharadwaj Vedula, Suhas Gangadharaiah +1
Entanglement entropy (EE) provides a powerful probe of quantum phases, yet its role in identifying topological phase transitions in disordered systems remains underexplored. We int…
