Harmonic Superfields in N=4 Supersymmetric Quantum Mechanics

Understand

This is a brief survey of applications of the harmonic superspace methods to the models of N=4 supersymmetric quantum mechanics (SQM).

• The main focus is on a recent progress in constructing SQM models with couplings to the background non-Abelian gauge fields.
• Besides reviewing and systemizing the relevant results, we present some new examples and make clarifying comments.
