Generalization of the matrix product ansatz for integrable chains
We present a general formulation of the matrix product ansatz for exactly integrable chains on periodic lattices. This new formulation extends the matrix product ansatz present on our previous articles ( F. C. Alcaraz and M. J. Lazo J. Phys. A: Math. Gen. 37 (2004) L1-L7 and J. Phys. A: Math. Gen. 37 (2004) 4149-4182.) In [1] (to which we refer hereafter as I) and [2], we formulate a matrix pro...
متن کاملThe matrix product ansatz for the six - vertex model
Recently it was shown that the eigenfunctions for the the asymmetric exclusion problem and several of its generalizations as well as a huge family of quantum chains, like the anisotropic Heisenberg model, Fateev-Zamolodchikov model, Izergin-Korepin model, Sutherland model, t − J model, Hubbard model, etc, can be expressed by a matrix product ansatz. Differently from the coordinate Bethe ansatz,...

A variational calculation of the energy levels of the class of PT-invariant quantum mechanical models described by the 2 Ž .N non-Hermitian Hamiltonian Hsp y ix with N positive and x complex is presented. The energy levels are determined 2 :Ž . Ž Ž . Ž .. Ž 2Ž .. Ž . by finding the stationary points of the functional H a,b,c ' H dx c x Hc x r H dx c x , where c x s C C b c Ž . ix exp a ix is a ...
متن کاملVariational optimization algorithms for uniform matrix product states
We combine the Density Matrix Renormalization Group (DMRG) with Matrix Product State tangent space concepts to construct a variational algorithm for finding ground states of one dimensional quantum lattices in the thermodynamic limit. A careful comparison of this variational uniform Matrix Product State algorithm (VUMPS) with infinite Density Matrix Renormalization Group (IDMRG) and with infini...
متن کاملMatrix product variational formulation for lattice gauge theory
For hamiltonian lattice gauge theory, we introduce the matrix product anzats inspired from density matrix renormalization group. In this method, wavefunction of the target state is assumed to be a product of finite matrices. As a result, the energy becomes a simple function of the matrices, which can be evaluated using a computer. The minimum of the energy function corresponds to the vacuum sta...
