Query: Quantum Monte Carlo calculation of the Fermi liquid parameters of the
  two-dimensional homogeneous electron gas   Fermi liquid theory is the basic paradigm within which we understand the
normal behavior of interacting electron systems, but quantitative values for
the parameters that occur in this theory are currently unknown in many
important cases. One such case is the two-dimensional homogeneous electron gas
(2D HEG), which is realized in a wide variety of semiconductor devices. We have
used quantum Monte Carlo (QMC) methods to calculate the Landau interaction
functions between pairs of quasiparticles. We use these to study the Fermi
liquid parameters, finding that finite-size effects represent a serious
obstacle to the direct determination of Fermi liquid parameters in QMC
calculations. We have used QMC data in the literature for other properties of
the 2D HEG to assemble a set of "best available" values for the Fermi liquid
parameters.
