Density of states of the interacting two-dimensional electron gas
E. Kogan, B. Rosenstein
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, whic…

Paramagnetic-ferromagnetic transition in a double-exchange model
Eugene Kogan, Mark Auslender
We study paramagnetic - ferromagnetic transition due to exchange interaction between classical localized magnetic moments and conduction electrons. We formulate the Dynamical Mean…
