Graphene: Kinks, Superlattices, Landau levels, and Magnetotransport
Matthew Killi, Si Wu, Arun Paramekanti
We review recent work on superlattices in monolayer and bilayer graphene. We highlight the role of the quasiparticle chirality in generating new Dirac fermion modes with tunable an…
Graphene under spatially varying external potentials: Landau levels, magnetotransport, and topological modes
Si Wu, Matthew Killi, Arun Paramekanti
Superlattices (SLs) in monolayer and bilayer graphene, formed by spatially periodic potential variations, lead to a modified bandstructure with extra finite-energy and zero-energy…
Band structures of bilayer graphene superlattices
Matthew Killi, Si Wu, Arun Paramekanti
We formulate a low energy effective Hamiltonian to study superlattices in bilayer graphene (BLG) using a minimal model which supports quadratic band touching points. We show that a…
Electric field control of spins in bilayer graphene: Local moment formation and local moment interactions
Matthew Killi, Dariush Heidarian, Arun Paramekanti
We study local moment formation for adatoms on bilayer graphene (BLG) within a mean-field theory of the Anderson impurity model. The wavefunctions of the BLG electrons induce stron…
