There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Title: Constructive approaches to frustrated magnetism: Moiré and Measurements
Abstract: Frustrated magnetism arises when spins interact through competing exchange interactions which cannot be simultaneously satisfied. When the frustrations are strong enough, exotic states can emerge such as long-range entangled spin liquids. Unfortunately, solid state materials are complicated and frustrations are hard to control: To this date, quantum spin liquids are still challenging to be realized in experiments. Naturally, researchers turn to more manageable experimental systems, in the hope of engineering frustrated magnetism constructively. I will discuss my recent works on spin liquids in two types of such manageable systems: moire heterostructures in van der Waals materials where many tuning knobs are available; and monitored quantum circuits where designer gates and measurements are exploited as new sources of frustrations.
Bio: Zhu-Xi received her B. S. in Economics at Fudan University in China. From 2014-2019 he did her Ph. D. in physics at the University of Utah. Between 2019-2022 she was a postdoc at the Kavli Institute for Theoretical Physics, University of California, Santa Barbara. In September 2022 she joined Harvard University as a postdoc. Her research is centered around discovering, understanding, and realizing exotic states of matter.
