Equivalence of the Variational Matrix Product Method and the Density Matrix Renormalization Group applied to Spin Chains
J. Dukelsky, M. A. Martin-Delgado, T. Nishino +1
We present a rotationally invariant matrix product method (MPM) of isotropic spin chains. This allows us to deal with a larger number of variational MPM parameters than those consi…

The Dimer-Hole-RVB State of the 2-Leg t-J Ladder: A Recurrent Variational Ansatz
G. Sierra, M. A. Martin-Delgado, J. Dukelsky +2
We present a variational treatment of the ground state of the 2-leg t-J ladder, which combines the dimer and the hard-core boson models into one effective model. This model allows…
