About Me

Hi I am Weicheng Ye 👋

🔭 I am currently a postdoctoral fellow at the University of British Columbia

👀 My research focuses on understanding quantum phases

– Mathematical theory behind quantum phases

– Characterization and identification of quantum phases

– Applying the concepts and ideas of quantum phases to other statistical systems

🤔 My research features interdisciplinary methods, including an extensive use of algebraic topology and machine learning

📫 My email address is victorye963 at gmail.com

💬 I love traveling and meeting new friends! Let’s chat when we are in the same city!

🔥 News

• I am currently in Guangzhou, China, and will travel to Hong Kong for one week and Boston for two weeks. Drop me a message if you want to chat!

•  🎉🎉 My paper Global structure in the presence of a topological defect is accepted by Communications in Mathematical Physics! This is by second collaboration with Arun Debray and Matthew Yu and I want to thank them again for the continual, fun collaborations! This paper is just built on the simple idea, i.e., how to incorporate tangential structures in generic topological defects.

•  🎉🎉 My paper Crystallography, Group Cohomology, and Lieb-Schultz-Mattis Constraints with Chunxiao Liu is accepted by Scipost! I sincerely thank Chunxiao for his brilliance, persistence, and hard work throughout this project, from which I truly respect.
  Check out Chunxiao’s personal webpage for his personal reflections on this huge project, and the Scipost submission page for referee reports, which we deeply appreciate.
