The physics of networks, or the network of physics?
This rhetorical question captures the interdisciplinary essence of our research group's mission — to explore the rich interplay between network science and both statistical and quantum physics.
Led by Professor Xiangyi "X" Meng, the group's research spans several areas:
[Mar, 2026] It was a great pleasure to be invited to present a colloquium "The shape of physical networks" for the Department of Engineering Sciences and Applied Mathematics at Northwestern: planitpurple.northwestern.edu/event....
[Mar, 2026] Our paper "Negativity percolation in continuous-variable quantum networks" is published in npj Quantum Information (doi.org/10.1038/s41534-026-01210-5). Congratulations to Yaqi and Yongtao!
[Mar, 2026] Our proposal (Harnessing Quantum Hysteresis in Spin Materials) has been selected for the Future of Computing Research Collaboration Grant sponsored by IBM. I am grateful for the contribution from Dr. Cogburn.
[Jan, 2026] Our paper "Surface optimization governs the local design of physical networks" is featured in Zhihu: zhihu.com/quest..., Physics Today: physicstoday.aip.org/news..., and Popular Mechanics: popularmechanics.com/scien....
[Jan, 2026] Our paper "A counter-intuitive low entanglement percolation threshold in mixed-state quantum networks" is published in Communications Physics (doi.org/10.1038/s42005-025-02459-6). Congratulations to Haigang, Omar, and Yongtao!
Prof. Xiangyi "X" Meng is an Assistant Professor in the Department of Physics, Applied Physics, and Astronomy at Rensselaer Polytechnic Institute (RPI). He earned his B.S. in microelectronics from Peking University and completed his Ph.D. in physics at Boston University (advised by Prof. Eugene Stanley). Prior to his role at RPI, he worked with Prof. Albert-László Barabási as a Postdoc at Northeastern University's Center for Complex Network Research, and with Prof. István Kovács as a Research Associate at Northwestern University.
Prof. Meng's research spans several areas of physics and network science, including quantum networks and quantum information, open quantum field theories, science of science, computational social science, physical and biological networks, scale-free network theories, information diffusion, tensor networks, and recurrent neural networks. He also applies interdisciplinary network science approaches to explore brains and econophysics.
Prof. Meng has published in prestigious journals such as Nature, PNAS, PNAS Nexus, Science Advances, Nature Human Behaviour, Nature Communications, Physical Review Letters, and Physical Review D. Prof. Meng is an affiliated faculty member with the NITMB in Chicago and a principal investigator with the Co-design Center for Quantum Advantage (C2QA). His research is funded by multiple agencies, including the DOE, IBM, and the Templeton Foundation.
