Keep following the charge: orbital reorganization across the time-reversal symmetry breaking transition in kagome superconductors

Abstract: Kagome superconductors AV3Sb5 provides a unique platform for studying charge orders and unusual electronic properties, including potential time-reversal symmetry breaking and a low-temperature nematic transition. A key question is the nature of the intermediate state between charge density wave order (CDW) and superconductivity. In a previous experiment (2410449) we have used avoided level crossing muSR to analyze how electronic charges reorganize in RbV3Sb5 as a function of the temperature. Our results have shown a clear a rearrangement of charge density below T ? 40 K, indicating a transition in the charge channel, likely electronic in origin, well below the CDW. Here we want to extend the analysis to the other two compounds of the family: KV3Sb5 and CsV3Sb5.
