Properties of the Two-Dimensional Electron Gas Close to the Fermi-Liquid Quantum Critical Point
M. Baldo, V. V. Borisov, J. W. Clark +2
The rearrangement of single-particle degrees of freedom of a dilute two-dimensional electron gas in the vicinity of the quantum critical point is examined within a microscopic appr…
