Charge response function and a novel plasmon mode in graphene
S. Gangadharaiah, A. M. Farid, E. G. Mishchenko
Polarizability of non-interacting 2D Dirac electrons has a 1/\sqrt{qv-ω} singularity at the boundary of electron-hole excitations. The screening of this singularity by long-range e…
Optical Conductivity of a Two-Dimensional Electron Liquid with Spin-Orbit Interaction
Abdel-Khalek Farid, Eugene Mishchenko
The interplay of electron-electron interactions and spin-orbit coupling leads to a new contribution to the homogeneous optical conductivity of the electron liquid. The latter is kn…
Spatial Structures in a Generalized Ginzburg-Landau Free Energy
Abdel-Khalek Farid, Yonggang Yu, Avadh Saxena +1
Searching for characteristic signatures of a higher order phase transition (specifically of order three or four), we have calculated the spatial profiles and the energies of a spat…
