A microscopic Ginzburg--Landau theory and singlet ordering in SrRuO
Glenn Wagner, Henrik S. Røising, Felix Flicker +1
The long-standing quest to determine the superconducting order of SrRuO (SRO) has received renewed attention after recent nuclear magnetic resonance (NMR) Knight shift expe…
Transport properties of multilayer graphene
Glenn Wagner, Dung X. Nguyen, Steven H. Simon
We apply the semi-classical quantum Boltzmann formalism for the computation of transport properties to multilayer graphene. We compute the electrical conductivity as well as the th…
Driven quantum dot coupled to a fractional quantum Hall edge
Glenn Wagner, Dung X. Nguyen, Dmitry L. Kovrizhin +1
We study a model of a quantum dot coupled to a quantum Hall edge of the Laughlin state, taking into account short-range interactions between the dot and the edge. This system has b…
Transport in bilayer graphene near charge neutrality: Which scattering mechanisms are important?
Glenn Wagner, Dung X. Nguyen, Steven H. Simon
Using the semiclassical quantum Boltzmann equation (QBE), we numerically calculate the DC transport properties of bilayer graphene near charge neutrality. We find, in contrast to p…
Quantum Boltzmann equation for bilayer graphene
Dung X. Nguyen, Glenn Wagner, Steven H. Simon
A-B stacked bilayer graphene has massive electron and hole-like excitations with zero gap in the nearest-neighbor hopping approximation. In equilibrium, the quasiparticle occupatio…
Interaction effects and charge quantization in single-particle quantum dot emitters
Glenn Wagner, Dung X. Nguyen, Dmitry L. Kovrizhin +1
We discuss a theoretical model of an on-demand single-particle emitter that employs a quantum dot, attached to an integer or fractional quantum Hall edge state. Via an exact mappin…
