Conductivity of graphene on boron nitride substrates
S. Das Sarma, E. H. Hwang
We calculate theoretically the disorder-limited conductivity of monolayer and bilayer graphene on hexagonal boron nitride (h-BN) substrates, comparing our theoretical results with…
Anomalous Hall response of topological insulators
Dimitrie Culcer, S. Das Sarma
The anomalous Hall effect due to the surface conduction band of 3D topological insulators with an out-of-plane magnetization is \textit{always} dominated by an intrinsic topologica…
Compressibility of graphene
D. S. L. Abergel, E. H. Hwang, S. Das Sarma
We develop a theory for the compressibility and quantum capacitance of disordered monolayer and bilayer graphene including the full hyperbolic band structure and band gap in the la…
Plasmon-phonon coupling in graphene
E. H. Hwang, Rajdeep Sensarma, S. Das Sarma
Collective excitations of coupled electron-phonon systems are calculated for both monolayer and bilayer graphene, taking into account the non-perturbative Coulomb coupling between…
Fractional quantum Hall effects in bilayers in the presence of inter-layer tunneling and charge imbalance
Michael R. Peterson, Z. Papic, S. Das Sarma
Two-component fractional quantum Hall systems are providing a major motivation for a large section of the physics community. Here we study two-component fractional quantum Hall sys…
Electron spin decoherence in isotope-enriched silicon
Wayne M. Witzel, Malcolm S. Carroll, Andrea Morello +2
Silicon is promising for spin-based quantum computation because nuclear spins, a source of magnetic noise, may be eliminated through isotopic enrichment. Long spin decoherence time…
