Quantum mechanics and the path integral -- The symmetric double well -- Decay of a meta-stable state -- Quantum field theory and the path integral -- Decay of the false vacuum -- Large orders in perturbation theory -- Quantum electrodynamics in 1+1 dimensions -- The Polyakov pro…
Instantons, or pseudoparticles, are solutions to the equations of motion in classical field theories on a Euclidean spacetime. Instantons are found everywhere in quantum theories as they have many applications in quantum tunnelling. Diverse physical phenomena may be described th…
This book explains in detail the key concepts, calculations and applications elucidating quantum tunnelling mediated by instantons, using the Feynman path integral.
