Pseudogap, Fermi liquid, Van Hove singularity and maxima of the compressibility and of the Knight shift as a function of doping in the two-dimensional Hubbard model
Y. M. Vilk, A. -M. S. Tremblay
Qualitative changes in thermodynamic and single-particle properties characterize the transition between the pseudogapped electronic liquid and the Fermi liquid. Recent cold-atom ex…
Antiferromagnetic pseudogap in the two-dimensional Hubbard model deep in the renormalized classical regime
Y. M. Vilk, Camille Lahaie, A. -M. S. Tremblay
Long-wavelength spin fluctuations prohibit antiferromagnetic long-range order at finite temperature in two dimensions. Nevertheless, the correlation length starts to grow rapidly a…
Criteria and analytical results for the Pseudogap at the Van Hove point in two dimensions
Y. M. Vilk
I establish the criteria and obtained analytical results for the pseudogap at the Van Hove (antinodal) point on the Fermi surface in two dimensions. The original criterion $ξ>> ξ_{…
An Improved Two-Particle Self-Consistent Approach
C. Gauvin-Ndiaye, C. Lahaie, Y. M. Vilk +1
The two-particle self-consistent approach (TPSC) is a method for the one-band Hubbard model that can be both numerically efficient and reliable. However, TPSC fails to yield physic…
Tracking the Footprints of Spin Fluctuations: A MultiMethod, MultiMessenger Study of the Two-Dimensional Hubbard Model
Thomas Schäfer, Nils Wentzell, Fedor Šimkovic +23
The Hubbard model represents the fundamental model for interacting quantum systems and electronic correlations. Using the two-dimensional half-filled Hubbard model at weak coupling…
Conserving approximations vs Two-Particle Self-Consistent Approach
S. Allen, A. -M. S. Tremblay, Y. M. Vilk
The conserving approximation scheme to many-body problems was developed by Kadanoff and Baym using the functional-derivative approach. Another approach for the Hubbard model also s…
