Entanglement in a first order quantum phase transition
J. Vidal, R. Mosseri, J. Dukelsky
The phase diagram of spins 1/2 embedded in a magnetic field mutually interacting antiferromagnetically is determined. Contrary to the ferromagnetic case where a second order quantu…

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…
