Extended Hubbard Model with spin-valley polarization DMRG solution

The data set for containing observables obtained by means of Density Matrix Renormalization Group for the Extended Hubbard model at filling n=2/3 and with spin-valley polarization included in the single-particle term. For all the considered case the on-site Hubbard repulsion U is set to 15|t| and |t| = 1. The phase for hopping termi is 2*pi/3.

Folders naming convention is following:

VXYZ

V stands for intersite interaction and XYZ is its magnitude.

In each folder there are following files:

- n_single

columns: i  j Re_up Im_up Re_dn Im_dn

Where: i,j are site indicies Re(Im)_up(dn) stand for the real(imaginary)  part of single particle equal-time Green function for up(dn) spin

- nn

columns: i  j  Re_up Im_up Re_dn Im_dn Re_(up+dn) Im_(up+dn)

Where: i,j are site indicies Re(Im)_up(dn) stand for the real(imaginary)  part of two particle equal-time Green function for up(dn) spin and two last columns correspond to <(n_i,up+n_i,dn)(n_j,up+n_j,dn)>

- ss

columns: i  j  Re  Im

Where: i,j are site indicies Re(Im) stand for the real(imaginary)  part of two particle equal-time Green function where S_i is total spin operator on site "i"

- szsz

columns: i  j  Re  Im

Where: i,j are site indicies Re(Im) stand for the real(imaginary)  part of two particle equal-time Green function where S_z is z-th component of  spin operator on site "i"

- spsm

columns: i  j  Re  Im Re Im

Where: i,j are site indicies Re(Im) stand for the real(imaginary)  part of two particle equal-time Green function and where S_i^(+/-) are spin ladder operators
