BACKGROUND INFORMATION

Xuejia Yu joined the School of Physics at Ningbo Eastern Institute of Technology (EIT) in 2025 as an Assistant Professor (independent Principal Investigator). He received his PhD in 2023 from the Center for Quantum Materials Science, School of Physics, Peking University, under the supervision of Prof. Limei Xu. He was awarded the Outstanding PhD Thesis Award by both Beijing Municipality and Peking University, as well as the Outstanding Graduate Award. His research focuses on the theoretical study of topological physics in quantum phase transitions within statistical and condensed-matter physics. He has played a leading role internationally in developing this emerging research direction. In particular, he was invited by the top-tier international review journal Physics Reports to author the first comprehensive review (56 pages) on the topological physics of quantum phase transitions as first and corresponding author. To date, he has published over 31 SCI-indexed papers in leading international journals. Among these, 10 papers were published as first and/or corresponding author in top-tier (Q1) journals, including one Physics Reports review (first and corresponding author), six papers in Physical Review Letters or as independent corresponding author in PRX Quantum, one paper in Science Bulletin, and two papers in Communications Physics. In addition, he has published 14 papers in the Physical Review series. Three of his publications have been selected as Highly Cited Papers by Web of Science. He is a founding Early-Career Editorial Board Member of Quantum Frontiers. He is the Principal Investigator of a National Natural Science Foundation of China (NSFC) Young Scientists Project (Category C) and serves as an NSFC peer reviewer. In recent years, he has delivered more than 30 invited talks at major national conferences in statistical physics, including the CPS Fall Meeting, the National Conference on Statistical Physics and Complex Systems, the West Lake Forum on Statistical Physics and Complex Systems, and the Southwest–Northwest Joint Seminar on Theoretical Physics.

RESEARCH FIELD

My research focuses on the theoretical and numerical study of quantum many-body systems and quantum phase transitions. My current interests include, but are not limited to:

Topological physics at quantum critical points and gapless symmetry-protected topological phases

Theoretical and numerical exploration (quantum Monte Carlo, density-matrix renormalization group (DMRG), and tensor-network approaches) of novel quantum phases and quantum phase transitions in many-body systems 

Phase transitions and critical phenomena in open quantum systems (mixed state quantum phases, quantum many body dynamics, quantum circuits) 

Interdisciplinary research at the interface of quantum simulation and many-body physics
