Stripe Formation in Fermionic Atoms on 2-D Optical Lattice inside a Box Trap: DMRG Studies for Repulsive Hubbard Model with Open Boundary Condition
M. Machida, M. Okumura, S. Yamada
We suggest that box shape trap enables to observe intrinsic properties of the repulsive Hubbard model in a fixed doping in contrast to the harmonic trap bringing about spatial vari…

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…
