Implication

Analyzes odd-frequency superconductivity in Josephson junctions, suggesting its potential in topological applications.

Key Points

  • The research aims to explore how odd-frequency pairing influences superconductivity in Josephson junctions coupled with magnetic textures.
  • Utilized a tight-binding Green function framework for analysis
  • Examined induced pair correlations under various magnetic conditions
  • Investigated spectral properties in both trivial and topological regimes
  • Analyzed impacts of nonmagnetic interruptions on Majorana states
  • Even-frequency singlet pairing dominates in the trivial regime
  • Odd-frequency triplet pairing coexists with Majorana states in the topological phase
  • Odd-frequency polarized triplets exhibit a divergent behavior when decoupled from Majorana states
  • Hybridization alters the frequency behavior of odd-frequency pairs, while stability of edge modes is preserved
