Description:
Author(s): Zhoushen Huang, W. Zhu, Daniel P. Arovas, Jian-Xin Zhu, and Alexander V. Balatsky We show that the topological index of a wave function, computed in the space of twisted boundary phases, is preserved under Hilbert space truncation, provided the truncated state remains normalizable. If truncation affects the boundary condition of the resulting state, the invariant index may acquir... [Phys. Rev. Lett. 120, 016403] Published Fri Jan 05, 2018
