Self-energy corrections to anisotropic Fermi surfaces
R. Roldan, M. P. Lopez-Sancho, F. Guinea +1
The electron-electron interactions affect the low-energy excitations of an electronic system and induce deformations of the Fermi surface. These effects are especially important in…

Deformation of anisotropic Fermi surfaces due to electron-electron interactions
Rafael Roldan, M. Pilar Lopez-Sancho, Francisco Guinea +1
We analyze the deformations of the Fermi surface induced by electron-electron interactions in anisotropic two dimensional systems. We use perturbation theory to treat, on the same…
