Non-perturbative Physics Study Group (NPPSG)

Objectives

Strongly interacting systems and the emergence of complex collective phenomena from microscopic quantum dynamics are central to understanding the universe and its underlying laws. Many fundamental problems in modern physics—from confinement in quantum chromodynamics to symmetry breaking in condensed matter systems—require a non-perturbative treatment to describe how rich structures and dynamics arise from fundamental interactions. A range of theoretical approaches has been developed to address these regimes, including lattice methods, functional approaches, holography, and newer ideas such as generalised symmetries and resurgence. Each provides partial access to otherwise inaccessible dynamics, yet they are often pursued separately despite clear structural similarities across fields.

The Non-Perturbative Physics Study Group aims to create a platform where these different approaches can be studied together and placed in dialogue. By bringing researchers from high-energy, nuclear, and condensed matter physics into a common framework, the initiative seeks to transfer methods, clarify underlying mechanisms, and explore connections between seemingly distinct systems. Such cross-disciplinary interaction is expected to advance long-standing problems, open new research directions, and foster collaboration.

The program will consist of seminars, informal discussion meetings, workshops, and intensive lecture courses, covering both physical applications and methodological developments. By combining diverse perspectives and techniques, the study group will provide an environment to rethink non-perturbative physics from multiple angles and to develop a more unified understanding of strongly interacting quantum systems.
