Quantum Field Theory: Mathematical Structure, Physical Foundations, and Contemporary Trajectories Hadis Deldar (21381167) Quantum optics and quantum optomechanics Quantum field theory -- Mathematical models <p dir="ltr">This article offers a comprehensive and high-level academic exposition of Quantum Field Theory (QFT), examining its mathematical foundations, physical principles, and contemporary directions. It systematically explores canonical and path integral quantization, gauge field dynamics, renormalization, and spontaneous symmetry breaking, while also addressing modern frameworks such as conformal field theory (CFT), topological QFT (TQFT), and the AdS/CFT correspondence. With rigorous formalism and emphasis on the deep interplay between geometry, topology, and quantum dynamics, this work aims to contextualize QFT not only as the backbone of the Standard Model but also as a central paradigm in emerging areas like quantum gravity and quantum information theory. Suitable for researchers and advanced students in theoretical physics.</p> 2026-09-29T12:31:08Z Text Online resource 10.6084/m9.figshare.34023747.v1 https://figshare.com/articles/online_resource/Quantum_Field_Theory_Mathematical_Structure_Physical_Foundations_and_Contemporary_Trajectories/34023747 CC BY 4.0
