Wednesday 5 Nov 2025, 08:00 → 19:15 US/Eastern

IAMM

Prof. Wang is an assistant professor in Emory University. He received bachelor's degree from University of Science and Technology of China in 2011 and Ph.D. degree from Stanford University in 2017. After that, he worked at Harvard University as an MPHQ postdoctoral fellow. In 2020, he started his independent career as an assistant professor at Clemson University and then the College of Science Dean's assistant professor. He moved his group to Emory University in August 2023. His research interests lie in the theoretical and computational study of quantum many-body problems and their experimental correspondence in solid-state materials and quantum science. He was the recipient of the DOE early career award and AFOSR young investigator award.

10:20 → 11:20 Seminar: Spectral Witness of Spin and Electronic Multipartite Entanglement in Solid-State Materials

Abstract: The rapidly advancing field of quantum materials demands increasingly precise methods for characterizing and controlling entanglement. While early progress was made in quantum optics, extending these approaches to complex many-body systems in quantum materials remains a major challenge. In this talk, I will introduce the entanglement witness framework for characterizing the bounds of entanglement depth using solid-state spectroscopies. In the first half of the talk, I will begin with the detection of spin entanglement in quantum magnets through the quantum metrology and spin quantum Fisher information (QFI). These metrics can be accessed via inelastic neutron scattering and resonant inelastic x-ray scattering (RIXS). Importantly, RIXS provides a route to extend such probes far out of equilibrium, enabling the control of entanglement with light. In the second half of the talk, I will move beyond entanglement among distinguishable local modes to explore entanglement in systems of indistinguishable fermions. I will present a generalized framework for multi-particle entanglement among electrons, based on the cumulant reduced density matrix and the nonlinear response characteristics of RIXS.
