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…
Spin-orbital effects in magnetized quantum wires and spin chains
Suhas Gangadharaiah, Jianmin Sun, Oleg A. Starykh
We present analysis of the interacting quantum wire problem in the presence of magnetic field and spin-orbital interaction. We show that an interesting interplay of Zeeman and spin…
Spin-orbit mediated anisotropic spin interaction in interacting electron systems
Suhas Gangadharaiah, Jianmin Sun, Oleg A. Starykh
We investigate interactions between spins of strongly correlated electrons subject to the spin-orbit interaction. Our main finding is that of a novel, spin-orbit mediated anisotrop…
