In the past ten years, the ideas of supersymmetry have been profitably applied to many
nonrelativistic quantum mechanical problems. In particular, there is now a much deeper …

The authors review the theory and phenomenology of instantons in quantum
chromodynamics (QCD). After a general overview, they provide a pedagogical introduction …

Seventy five years ago, three remarkable papers by Schrödinger, Kennard and Darwin were
published. They were devoted to the evolution of Gaussian wave packets for an oscillator, a …

We study the quantum-mechanical properties of a supermembrane and examine the nature
of its ground state. A supersymmetric gauge theory of area-preserving transformations …

Stochastic quantization provides a novel and interesting connection between quantum field
theory and statistical mechanics, with new applications also in numerical simulations of field …

The massless limit of supersymmetric QCD with N ƒ flavors and N colors is analyzed in
detail. For N ƒ< N there is a unique superpotential which might be generated by non …

Various techniques for the computation of the fractional fermion number of topological
solitons are reviewed. First the original calculation by Jackiw and Rebbi and the relevance …

The term'nonclassical states' refers to the quantum states that cannot be produced in the
usual sources of light, such as lasers or lamps, rather than those requiring more …

This review is an elementary introduction to supersymmetry. The example of supersymmetric
quantum mechanics is used to discuss the basic concepts of supersymmetry and its …
