Direct Extension of Density-Matrix Renormalization Group toward 2-Dimensional Quantum Lattice Systems: Studies for Parallel Algorithm, Accuracy, and Performance
S. Yamada, M. Okumura, M. Machida
We parallelize density-matrix renormalization group to directly extend it to 2-dimensional (-leg) quantum lattice models. The parallelization is made mainly on the exact diagona…
