Analysis
This paper investigates unconventional superconductivity in kagome superconductors, specifically focusing on time-reversal symmetry (TRS) breaking. It identifies a transition to a TRS-breaking pairing state driven by inter-pocket interactions and density of states variations. The study of collective modes, particularly the nearly massless Leggett mode near the transition, provides a potential experimental signature for detecting this TRS-breaking superconductivity, distinguishing it from charge orders.
Key Takeaways
- •Identifies a TRS-breaking superconducting state in kagome superconductors.
- •The TRS-breaking state is driven by inter-pocket interactions and density of states variations.
- •Predicts a nearly massless Leggett mode as a signature of TRS-breaking superconductivity.
- •Provides insights into the rich superconducting physics of kagome metals.
