The Density Matrix Renormalization Group for spin-1/2-quantum chains: A demonstration program — •Thomas Köhler, Piet Dargel, and Andreas Honecker — Institut für Theoretische Physik, Georg-August-Universität Göttingen, 37077 Göttingen, Germany

We have implemented a density matrix renormalization group algorithm in the formulation of Matrix-Product-States as Web Applet. This implementation offers direct visualization of the running algorithm including energy, static correlation functions and entropy convergence. It offers the computation of several different Spin-1/2-Hamiltonians and we have explicitly evaluated the Ising-chain in a transversal magnetic field.
