We present conductance measurements of a quantum point contact (QPC) in bilayer graphene (BLG). Beyond the expected quantized conductance plateaus reflecting spin-and-valley degeneracy, we observe an additional plateau resembling the \u201c0.7 anomaly\u201d, exhibiting signatures of Kondo physics, with a Kondo temperature ranging from approximately 0.5 up to well above 5 K at zero magnetic field, corresponding to energies between 43 and 430 \u03bceV. Because the QPC is spin-and-valley degenerate within our experimental resolution (110 \u03bceV), according to the prevailing Kondo model, these results are consistent with a transition between 4-fold degenerate SU(4) and 2-fold degenerate spin-valley locked SU(2) interactions. Furthermore, we break the degeneracy of the lowest subband by an out-of-plane magnetic field and show that Kondo signatures remain, demonstrating the versatility of BLG QPCs.<\/jats:p>","DOI":"10.1021\/acs.nanolett.6c01707","type":"journal-article","created":{"date-parts":[[2026,9,16]],"date-time":"2026-09-16T11:02:02Z","timestamp":1789556522000},"page":"12620-12627","source":"Crossref","is-referenced-by-count":1,"title":["Tunable Kondo\nBehavior in a Bilayer Graphene Quantum\nChannel"],"prefix":"10.1021","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9179-1570","authenticated-orcid":true,"given":"Josep","family":"Ingla-Ayne\u0301s","sequence":"first","affiliation":[{"name":"Delft University of Technology , , Lorentzweg 1 , ,","place":["Delft, The Netherlands, 2628 CJ"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Serhii","family":"Volosheniuk","sequence":"additional","affiliation":[{"name":"Delft University of Technology , , Lorentzweg 1 , ,","place":["Delft, The Netherlands, 2628 CJ"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3490-5356","authenticated-orcid":true,"given":"Talieh S.","family":"Ghiasi","sequence":"additional","affiliation":[{"name":"Delft University of Technology , , Lorentzweg 1 , ,","place":["Delft, The Netherlands, 2628 CJ"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Angelika","family":"Knothe","sequence":"additional","affiliation":[{"name":"Universita\u0308t Regensburg , , ,","place":["Regensburg, Germany, D-93040"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3701-8119","authenticated-orcid":true,"given":"Kenji","family":"Watanabe","sequence":"additional","affiliation":[{"name":"National Institute for Materials Science , , 1-1 Namiki , ,","place":["Tsukuba, Japan, 305-0044"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1467-3105","authenticated-orcid":true,"given":"Takashi","family":"Taniguchi","sequence":"additional","affiliation":[{"name":"National Institute for Materials Science , , 1-1 Namiki , ,","place":["Tsukuba, Japan, 305-0044"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0828-0310","authenticated-orcid":true,"given":"Vladimir I.","family":"Fal\u2019ko","sequence":"additional","affiliation":[{"name":"University of Manchester , , Booth Street East , ,","place":["Manchester, United Kingdom, M13 9PL"]},{"name":"University of Manchester , , Oxford Road , ,","place":["Manchester, United Kingdom, M13 9PL"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5385-0282","authenticated-orcid":true,"given":"Herre S.
