Overview

Analysis reveals instanton effects on bosonic and supersymmetric kinks with degenerate masses, implying implications for quantum tunneling.

Key Points

  • Instanton effects modify the behavior of degenerate kinks in two-dimensional scalar field models, enhancing mixing in bosonic theories.
  • Comparative analysis shows strong differences between bosonic and supersymmetric transition amplitudes due to fermionic zero modes.
  • Employing Wess-Zumino models with two and four supercharges illustrates the significance of instantons in kink backgrounds.
  • Findings highlight the complexity of supersymmetry in relation to instanton calculus and degenerate mass scenarios.
