About the Authors
  • 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 through quantum tunnelling, for example: the Josephson effect, the decay of meta-stable nuclear states, band formation in tight binding models of crystalline solids, the structure of the gauge theory vacuum, confinement in 2+1 dimensions, and the decay of superheated or supercooled phases. Drawing inspiration from Sidney Coleman's Erice lectures, this volume provides an accessible, detailed introduction to instanton methods, with many applications, making it a valuable resource for graduate students in many areas of physics, from condensed matter, particle and nuclear physics, to string theory.

    • Each calculation in Sidney Coleman's precise notes 'Uses of Instantons' has been presented in great detail
    • Adds several new applications that have not been covered previously in any book
    • Includes a chapter on instantons in supersymmetric theories which opens the door to a vast literature that exists on this topic

    Manu Paranjape has been a professor at the Université de Montréal for the past thirty years. In this time, he has worked on quantum field theory, the Skyrme model, non-commutative geometry and conformal gravity. Whilst working on induced fermion number, he discovered induced angular momentum on flux tube solitons, and more recently he discovered the existence of negative mass bubbles in de Sitter space, which merited a prize in the Gravity Research Foundation essay competition.
