Diffusive density response of electrons in anisotropic multiband systems
Jeonghyeon Suh, Sunghoon Kim, E. H. Hwang +1
We explicitly calculate the density-density response function with conserving vertex corrections for anisotropic multiband systems in the presence of impurities including long-rang…
Impurity scattering induced carrier transport in twisted bilayer graphene
E. H. Hwang, S. Das Sarma
We theoretically calculate the impurity-scattering induced resistivity of twisted bilayer graphene at low twist angles where the graphene Fermi velocity is strongly suppressed. We…
Linear-in-T resistivity in dilute metals: A Fermi liquid perspective
E. H. Hwang, S. Das Sarma
We consider a short-range deformation potential scattering model of electron-acoustic phonon interaction to calculate the resistivity of an ideal metal as a function of temperature…
Plasmon-pole approximation for many-body-effects in extrinsic graphene
E. H. Hwang, Robert E. Throckmorton, S. Das Sarma
We develop the plasmon-pole approximation (PPA) theory for calculating the carrier self-energy of extrinsic graphene as a function of doping density within analytical approximation…
Dimensionally mixed coupled collective modes
E. H. Hwang, Ben Yu-Kuang Hu, S. Das Sarma
We develop the diagrammatic formulation of the many-body theory for the coupled collective modes in interacting electron systems of different dimensions. The formalism is then appl…
Diluted magnetic Dirac-Weyl materials: Susceptibility and ferromagnetism in three-dimensional chiral gapless semimetals
Sanghyun Park, Hongki Min, E. H. Hwang +1
We theoretically investigate the temperature-dependent static susceptibility and long-range magnetic coupling of three-dimensional (3D) chiral gapless electron-hole systems (semime…
