We study the influence of electron-electron interactions on the density of states (DOS) of clean 2D electron gas. We confirm the linear cusp in the DOS around the Fermi level, which was obtained previously. The cusp crosses over to a pure logarithmic dependence further away from the Fermi surface.

We study the influence of electron-electron interactions on the density of states (DOS) of a clean two-dimensional electron gas. We find that the linear cusp in the DOS around the Fermi level, which was obtained previously, has an additional logarithmic factor. The cusp crosses over to a pure logarithmic dependence further away from the Fermi surface.
