Exchange effects in a two-dimensional Fermi liquid

We investigate the possibility of simulating exchange effects in a two-dimensional fermion liquid within a model of distinguishable particles. For this purpose, we intend to reproduce both bulk and microscopic properties of the system of N indistinguishable particles, as predicted by the Landau theo...
