Field Theory Methods for Multiscale Description of Quantum Systems - IPAM at UCLA

Explore field theory methods for multiscale description of quantum systems in this comprehensive lecture presented by Matteo Gori from the University of Luxembourg at IPAM's Advancing Quantum Mechanics with Mathematics and Statistics Tutorials. Delve into the origins of quantum field theory and its evolution from describing quantum systems consistent with special relativity to its current role in explaining fundamental interactions. Discover how field theories encompass general concepts crucial for understanding multiscale phenomena, including order/disorder, symmetry breakdown, collective modes, correlations, and macroscopic quantum phenomena. Gain insights into the unique aspects of quantum field theory, such as inequivalent Hilbert space representations, and their applications in condensed matter physics and biology. Enhance your understanding of how quantum field theory bridges the gap between microscopic fundamental interactions and macroscopic observable physics.
