Abstract
Tensor networks are a powerful framework for describing quantum many-body states. They effectively overcome the challenge posed by the exponential size of the quantum many-body Hilbert space by combining local data into a globally defined state. However, certain quantum materials have ground states that cannot be easily captured using tensor network states. A prime example of this is the Chern insulator, which exhibits the quantum anomalous Hall effect and can support dissipationless current at its boundary. In this talk, we will explore how concepts derived from entanglement renormalization can be employed to facilitate the construction of a tensor network representation for Chern insulators.
Biography
Dr. Hoi Chun (Adrian) Po is a condensed matter theorist and he is broadly interested in the study of collective phenomena arising from a large number of quantum particles. He grew up in Hong Kong and obtained his bachelor’s degree from the Chinese University of Hong Kong in 2013. He began his doctoral studies at the University of California, Berkeley, but transferred to Harvard University in 2016 together with the move of his thesis advisor, Prof. Ashvin Vishwanath. After obtaining his PhD from Harvard in 2018, he moved to MIT as a Pappalardo Postdoctoral Fellow. He returned to Hong Kong and joined HKUST as an assistant professor in 2021.
