Equilibration of Quantum hall edges in symmetry broken bilayer graphene
Chandan Kumar, Saurabh Kumar Srivastav, Anindya Das
Equilibration of quantum Hall edges is studied in a high quality dual gated bilayer graphene device in both unipolar and bipolar regime when all the degeneracies of the zero energy…

Localization physics in graphene Moire superlattices
Chandan Kumar, Saurabh Kumar Srivastav, Priyo Adhikary +3
Non-trivial Berry phase of graphene leads to unusual quantum correction to the conductivity. Berry phase of pi in single layer graphene (SLG) and 2pi in bi-layer graphene (BLG) is…
