Reduced density matrices renormalization

To complete the definition of the renormalization step for the left block, we also need to construct the new matrix representations of the second-quantized operators. In the product basis Z <8> p, matrix representations can be formed by the product of operator matrices associated with left, p j and the partition orbital p separately. Then, given such a product representation of O say, the renormalized representation O in the reduced M-dimensional basis / of LEFIi. p is obtained by projecting with the density matrix eigenvectors L defined above,... 

To summarize, we have presented a review on the renormalization group theory in the reduced many-body density matrix basis (DMRG method), and we have applied it to conjugated organic systems, with both short range and long range Coulomb interaction potentials. We... 

Figure 7.2 Replica HNC results for the temperatures corresponding to the stability limits of the homogeneous isotropic phase of confined Stodonayer fluids (and for the bulk) as a function of the renormalized fluid density (tf = npa /6). Curves are labeled according to values of the reduced matrix density pm-...
