Ferromagnetism in the Infinite-U Hubbard Model
Shoudan Liang, Hanbin Pang
We have studied the stability of the ferromagnetic state in the infinite-U Hubbard model on a square lattice by approximate diagonalization of finite lattices using the density mat…

Can Density-matrix renormalization group be Applied to two dimensional systems?
Shoudan Liang, Hanbin Pang
In order to extend the density-matrix renormalization-group (DMRG) method to two-dimensional systems, we formulate two alternative methods to prepare the initial states. We find th…
