Characterizing Charge Interactions in Hole-Doped Kagome Superconductors

Oral-In-person

Abstract

Superconductivity (SC) and charge-density wave (CDW) order often interact in complex ways that influence the properties of many quantum materials. In hole-doped kagome compounds, long-range CDW order is suppressed at the minumum between the two SC domes. Doping inevitably introduces defects and inhomogeneities into the lattice, which may interfere with the CDW order. Thus, it becomes challenging to distinguish between the effects of CDW, disorder and tuning the Fermi level by doping when determining what sustains SC. In this talk, we discuss the implication of our nuclear quadrupole resonance (NQR) findings on the complex interplay between CDW and SC in the kagome compounds. These findings highlight the significant role of disorder when describing the interaction between CDW and SC.
