Here, we perform a systematic measurement of elastoresistance in two hole-doped CsV 3 Sb 5 series: CsV 3 − x Ti x Sb 5 (x = 0, 0.03, 0.05 and 0.09) and CsV 3 Sb 5 − y Sn y (y = 0.04 and 0.06). The elastoresistance coefficient in all samples exhibits a discontinuous jump at CDW transition temperature ( T CDW ), followed by an anomaly at a lower temperature ( T* ). Strikingly, the T* displays an inverse relationship with the superconducting transition temperature ( T c ), suggesting a distinctive intertwinement. Using a Ginzburg-Landau framework, we attribute the jump at T CDW to a triple- Q CDW phase driven by lattice instability. In contrast, the anomaly at T* reflects an intertwinement between triple- Q CDW and an incipient electronic order. Our present findings elucidate the interplay of electronic and lattice degrees of freedom in stabilizing intertwined orders and underscore the role of doping in tuning emergent quantum phases in kagome systems.

Using a Ginzburg-Landau framework, we attribute the jump at \u003cem\u003eT\u003c/em\u003e\u003csub\u003e\u003cem\u003eCDW\u003c/em\u003e\u003c/sub\u003e to a triple-\u003cem\u003eQ\u003c/em\u003e CDW phase driven by lattice instability. In contrast, the anomaly at \u003cem\u003eT*\u003c/em\u003e reflects an intertwinement between triple-\u003cem\u003eQ\u003c/em\u003e CDW and an incipient electronic order. Our present findings elucidate the interplay of electronic and lattice degrees of freedom in stabilizing intertwined orders and underscore the role of doping in tuning emergent quantum phases in kagome systems.\u003c/p\u003e","manuscriptTitle":"Intertwined charge density wave order in vanadium based kagome superconductors","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-11-18 09:44:36","doi":"10.21203/rs.3.rs-7904037/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"decision","content":"Revision requested","date":"2025-12-28T21:35:31+00:00","index":"","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-12-13T19:42:30+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-12-04T13:55:10+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"213031825838303630966713255722535131624","date":"2025-11-21T13:23:24+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"21069853416049460376767197594260181764","date":"2025-11-12T10:39:12+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"59144341138769439514900592327345551909","date":"2025-11-08T03:37:26+00:00","index":"hide","fulltext":""},{"type":"reviewersInvited","content":"","date":"2025-11-08T00:22:49+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2025-11-03T02:35:59+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2025-10-30T11:40:05+00:00","index":"","fulltext":""},{"type":"submitted","content":"npj Quantum Materials","date":"2025-10-20T09:01:17+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"npj-quantum-materials","isNatureJournal":false,"hasQc":false,"allowDirectSubmit":false,"externalIdentity":"npjquantmats","sideBox":"Learn more about [npj Quantum Materials](http://www.nature.com/npjquantmats/)","snPcode":"41535","submissionUrl":"https://mts-npjquantmats.nature.com/cgi-bin/main.plex","title":"npj Quantum Materials","twitterHandle":"","acdcEnabled":true,"dfaEnabled":true,"editorialSystem":"ejp","reportingPortfolio":"NPJ","inReviewEnabled":true,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"03bde1be-f97e-4469-894c-b4d9ce43c648","owner":[],"postedDate":"November 18th, 2025","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"in-revision","subjectAreas":[{"id":57864166,"name":"Physical sciences/Materials science"},{"id":57864167,"name":"Physical sciences/Physics"}],"tags":[],"updatedAt":"2026-04-24T03:54:41+00:00","versionOfRecord":[],"versionCreatedAt":"2025-11-18 09:44:36","video":"","vorDoi":"","vorDoiUrl":"","workflowStages":[]},"version":"v1","identity":"rs-7904037","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-7904037","identity":"rs-7904037","version":["v1"]},"buildId":"8U1c8b4HqxoKbykW_rLl7","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
