abstract:The phase structure of quantum field theory offers a useful guide to physics beyond the Standard Model. In this talk, I discuss how conformal dynamics, asymptotic safety and strong phase transitions can constrain BSM model building and phenomenology. A central focus is the realization of UV completion through interacting fixed points, using large- resummation and GUT-inspired embeddings such as Pati–Salam and trinification models. These constructions address the Landau pole problem and connect UV boundary conditions to low-energy observables through renormalization-group flows. I will also discuss gravitational-wave signatures from strong first-order phase transitions and briefly comment on large-charge methods as a complementary resummation tool for strongly coupled sectors.
bio:Dr. Zhi-Wei Wang is currently a Research Professor at the University of Electronic Science and Technology of China (UESTC) and Director of the Subatomic Physics Institute (SPIN). He has been selected for the Sichuan Emei Talent Program, the Chengdu Rongpiao Talent Program, and UESTC’s Hundred Talents Program. He pursued his Ph.D. studies at the University of Saskatchewan, Canada, from 2012 to 2016. In 2017, he received the Governor General’s Academic Gold Medal of Canada and the Ishwar Gupta Physics Prize. He subsequently held postdoctoral and senior postdoctoral positions at the University of Waterloo, Canada (2016–2019), CP3-Origins in Denmark (2016–2021), and Lund University, Sweden (2021–2022).
Dr. Wang’s research focuses on theoretical high-energy physics, especially strong-coupling dynamics and the breakdown of perturbation theory in particle physics and the early Universe. He is dedicated to developing non-perturbative computational methods and making testable theoretical predictions. He has made a series of contributions to strongly coupled dark matter, gravitational waves from phase transitions, multimessenger test frameworks, asymptotic safety, and higher-order resummation. To date, he has completed 44 academic papers, 34 of which have been published in leading international journals, including five papers in Physical Review Letters and one ESI Highly Cited Paper, all with him as leading author. One PRL paper was selected as an Editors’ Suggestion; six papers have each received more than 50 citations, and one has received more than 100 citations.
