Anisotropic Fermionic Quasiparticles
Seongjin Ahn, S. Das Sarma
We have carried out a comprehensive investigation of the quasiparticle properties of a two-dimensional electron gas, interacting via the long-range Coulomb interaction, in the pres…
Theroy of anisotropic plasmons
Seongjin Ahn, S. Das Sarma
We develop the complete theory for the collective plasmon modes of an interacting electron system in the presence of explicit mass (or velocity) anisotropy in the corresponding non…
Microscopic bath effects on noise spectra in semiconductor quantum dot qubits
Seongjin Ahn, S. Das Sarma, J. P. Kestner
When a system is thermally coupled to only a small part of a larger bath, statistical fluctuations of the temperature (more precisely, the internal energy) of this "sub-bath" aroun…
Fermi-surface topology and renormalization of bare ellipticity in an interacting anisotropic electron gas
Seongjin Ahn, Sankar Das Sarma
We investigate effects of electron-electron interactions on the shape of the Fermi surface in an anisotropic two-dimensional electron gas using the `RPA-GW' self-energy approximati…
