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…
Chiral Rashba spin textures in ultra-cold Fermi gases
Jay D. Sau, Rajdeep Sensarma, Stephen Powell +2
Spin-orbit coupling is an important ingredient in many recently discovered phenomena such as the spin-Hall effect and topological insulators. Of particular interest is topological…
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…
The Prediction of a Gapless Topological "Haldane Liquid" Phase in a One-Dimensional Cold Polar Molecular Lattice
J. P. Kestner, Bin Wang, Jay D. Sau +1
We show that ultracold two-component fermionic dipolar gases in an optical lattice with strong two-body on-site loss can be used to realize a tunable effective spin-one model. Ferm…
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…
Chirality-dependent phonon-limited resistivity in multiple layers of graphene
Hongki Min, E. H. Hwang, S. Das Sarma
We develop a theory for the temperature and density dependence of phonon-limited resistivity in bilayer and multilayer graphene, and compare with the corresponding monolayer…
