Entanglement and quantum phase transition in the asymmetric Hubbard chain: density-matrix renormalization group calculations

W. L. Chan, S. J. Gu

We study the ground state quantum phase transition by means of entanglement in the one-dimensional asymmetric Hubbard model with open boundary condition. The local entanglement bet…
