The Uses of Instantons

  title={The Uses of Instantons},
  author={S. Coleman},
In the last two years there have been astonishing developments in quantum field theory. We have obtained control over problems previously believed to be of insuperable difficulty and we have obtained deep and surprising (at least to me) insights into the structure of the leading candidate for the field theory of the strong interactions, quantum chromodynamics. These goodies have come from a family of computational methods that are the subject of these lectures. 
Vacuum decay by inverse scattering
We discuss the decay of false vacua which originate from quantum mechanical effects. In particular we examine the 1N expansion of the O(N) λφ4 model. This model has an effective potential which isExpand
Low Energy Physics from Superstrings
When I originally agreed to accept the kind invitation to lecture at the NATO Summer School in Cargese, my topic was to be the theory of CP violation. The developments of the past year have resultedExpand
Instantons in unusual settings
Abstract Instantons may still be an important feature of a quantum system even if they are not exact solutions of the classical equations. This is illustrated in a simple quantum mechanics problemExpand
The Evolution of Quantum Field Theory, From QED to Grand Unification
In the early 1970s, after a slow start, and lots of hurdles, Quantum Field Theory emerged as the superior doctrine for understanding the interactions between relativistic sub-atomic particles. AfterExpand
The role of instantons in scale-invariant gauge theories
Abstract Instanton calculations in scale-invariant gauge theories, such as QCD, have long been plaqued by divergences at large distances where strong coupling effects are important. Furthermore,Expand
Supersymmetry on the lattice
Abstract.Supersymmetric gauge theories are fascinating for a number of reasons. However, unlike QCD, it was not known until recently how to devise a nonperturbative lattice construction for these Expand
Tying up instantons with anti-instantons
In quantizing classical mechanical systems one often sums over the classical trajectories as in localization formulas, but also takes into account the contributions of the "instanton gas": a set ofExpand
Some Recent Applications of Instanton and Related Techniques in Condensed-Matter Physics
"In recent years the ideas of decay of a metastable state by quantum tunnelling of a field, and also of tunnelling between degenerate vacua, have played a major role in particle physics. AnalogousExpand
A small, but to my mind significant, area of development taking place in Euclidean field theories is discussed, corresponding to Yang-Mills solitons or monopoles. Expand
Higher-order quantum corrections in the presence of an instanton background field
Abstract We calculate the ultraviolet divergent part of the two-loop correction to the vacuum energy in the presence of an instanton background field. We verify that the coupling constant and fermionExpand


Computation of the quantum effects due to a four-dimensional pseudoparticle
A detailed quantitative calculation is carried out of the tunneling process described by the Belavin-Polyakov-Schwarz-Tyupkin field configuration. A certain chiral symmetry is violated as aExpand
Quantum Fluctuations of Pseudoparticles
Abstract Using the O(5) form of the pseudoparticle solution in gauge theories, we have calculated the eigenspectrum of small oscillations near this solution. It appears that the equation for theExpand
CP Conservation in the Presence of Pseudoparticles
We give an explanation of the $\mathrm{CP}$ conservation of strong interactions which includes the effects of pseudoparticles. We find it is a natural result for any theory where at least one flavorExpand
Problem of Strong $P$ and $T$ Invariance in the Presence of Instantons
The requirement that P and T be approximately conserved in the color gauge theory of strong interactions without arbitrary adjustment of parameters is analyzed. Several possibilities are identified,Expand
A new light boson
It is pointed out that a global U(1) symmetry, that has been introduced in order to preserve the parity and time-reversal invariance of strong interactions despite the effects of instantons, wouldExpand
The structure of the gauge theory vacuum
Abstract The finite action Euclidean solutions of gauge theories are shown to indicate the existence of tunneling between topologically distinct vacuum configurations. Diagonalization of theExpand
Vacuum Periodicity in a Yang-Mills Quantum Theory
We propose a description of the vacuum in Yang-Mills theory and arrive at a physical interpretation of the pseudoparticle solution and the attendant violation of symmetries. The existence ofExpand
Quark confinement and topology of gauge theories
Abstract The phenomenon of quark confinement is known to be connected with the restoration of apparently broken gauge symmetry. In this paper we focus on a special mechanism which is responsible forExpand
Symmetry Breaking Through Bell-Jackiw Anomalies
In models of fermions coupled to gauge fields certain current-conservation laws are violated by Bell-Jackiw anomalies. In perturbation theory the total charge corresponding to such currents seems toExpand
Vacuum Instability and Higgs Scalar Mass
A procedure is given to estimate the decay probability of a metastable vacuum state in quantum field theory. As an application, in the Weinberg-Salam model the lower bound (for theta/sub W/=35degree)Expand
