Classification of topological phases in one dimensional interacting non-Hermitian systems and emergent unitarity Wenjie Xi, Zhi-Hao Zhang, Zheng-Cheng Gu, Wei-Qiang Chen arXiv:1911.01590 Abstract: Topological phases in non-Hermitian systems have become a fascinating subject recently. In this paper, we attempt to classify topological phases in 1D interacting non-Hermitian systems. We begin with the non-Hermitian generalization of […]
A topological phase transition on the edge of the 2d Z2 topological order Wei-Qiang Chen, Chao-Ming Jian, Liang Kong, Yi-Zhuang You, Hao Zheng arXiv:1903.12334 Abstract: The unified mathematical theory of gapped and gapless edges of 2d topological orders was developed by two of the authors. It provides a powerful tool to study pure edge topological […]
