Description

This zip archive contains the DQMC data sets for the \beta=1/T resolved double
occupancy, internal energy per site, antiferromagnetic structure factor and
charge density wave structure factor obtained with the ALF Code.
The computations have been carried out on a square lattice at half filling for
the Hubbard model, the U-V model and the long-range Coulomb(LRC)-Hubbard model.
Every model is computed at fixed U/t=1.9.

The naming convention of the csv-files is the following:
    V0.0 = Hubbard model
    V0.x = U-V model with V/t=0.x
    Vcx.x = LRC-Hubbard model with V_C/t=x.x
    
    - dat_docc_{\Delta\tau}_V{x}.csv = double occupancy at \Delta\tau={0.05, 0.1, 0.2}
    - dat_docc_{\Delta\tau}_V{x}_err.csv = corresponding statistical error
    - dat_energy_0.1_V{x}.csv = internal energy at \Delta\tau=0.1
    - dat_energy_0.1_V{x}_err.csv = corresponding statistical error
    - dat_saf_0.1_V{x}.csv = antiferromagnetic structure factor at \Delta\tau=0.1
    - dat_saf_0.1_V{x}_err.csv = corresponding statistical error
    - dat_scdw_0.1_V{x}.csv = charge density wave structure factor at \Delta\tau=0.1
    - dat_scdw_0.1_V{x}_err.csv = corresponding statistical error

The structure of each file is to be read column-wise:
    \beta,   L=8,   L=10,   L=12,   L=16,   L=18,   L=20
