Spin Liquid in the Multiple-Spin Exchange Model on the Triangular Lattice: 3 He on Graphite
TL;DR: In this article, the authors investigated the phase diagram of the MSE model on the triangular lattice and found a transition separating a ferromagnetic phase from a nonmagnetic gapped spin liquid phase.

Momentum Distribution of the Homogeneous Electron Gas
Markus Holzmann,B. Bernu,Carlo Pierleoni,Jeremy McMinis,David M. Ceperley,Valerio Olevano,Luigi Delle Site +6 more
TL;DR: The results on the renormalization factor allow us to validate approximate G0W0 calculations concerning quasiparticle properties over a broad density region and show that, near the Fermi surface, vertex corrections and self-consistency aspects almost cancel each other out.

Specific heat of the S = 1 2 Heisenberg model on the kagome lattice: High-temperature series expansion analysis
Grégoire Misguich,B. Bernu +1 more
TL;DR: In this article, the specific heat of the antiferromagnetic spin-1/2 Heisenberg model on the kagome lattice was computed using a recently introduced technique to analyze high-temperature series expansion.

Finite-size analysis of the Fermi liquid properties of the homogeneous electron gas
TL;DR: In this paper, the authors analyze the extrapolation to the thermodynamic limit of Fermi liquid properties of the homogeneous electron gas in two and three dimensions using field theory.

Metal-insulator transition in the Hartree-Fock phase diagram of the fully polarized homogeneous electron gas in two dimensions
TL;DR: The ground state of the two-dimensional fully polarized electron gas within the Hartree-Fock approximation without imposing any particular symmetries on the solutions was determined numerically in this article.
