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 <n_i,up(dn) n_j,up(dn)> 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 <S_i S_j> 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 <S_z S_z> 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 <S_i^(+)S_j^(-)> and <S_i^(-)S_j^(+)> where S_i^(+/-) are spin ladder operators This data set is a result of research which was founded by National Science Centre, Poland (NCN) according to decision 2021/42/E/ST3/00128.
