Here, starting from isolated magnetic impurities in the Kondo regime, we investigate the formation of the finite size analogue of a heavy Fermi liquid. We build regularly-spaced chains of Co adatoms on a metallic surface by atomic manipulation. Scanning tunneling spectroscopy is used to obtain maps of the Kondo resonance intensity with sub-atomic resolution. For sufficiently small interatomic separation, the spatial distribution of Kondo screening does not coincide with the position of the adatoms. It also develops enhancements at both edges of the chains. Since we can rule out any other interaction between Kondo impurities, this is explained in terms of the indirect hybridization of the Kondo orbitals mediated by a coherent electron gas, the mechanism that causes the emergence of heavy quasiparticles in the thermodynamic limit. info:eu-repo/grantAgreement/EUR/ERDF/EFA194-16TNSI info:eu-repo/grantAgreement/EC/H2020/676598/EU/Materials design at the eXascale/MaX This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 676598-MaX info:eu-repo/grantAgreement/ES/MINECO/FIS2015-64886-C5-3-P info:eu-repo/grantAgreement/ES/MINECO/MAT2013-46593-C6-3-P info:eu-repo/grantAgreement/ES/MINECO/MAT2015-66888-C3-2R info:eu-repo/grantAgreement/ES/MINECO/MAT2016-78293-C6-6R info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 12.121 2019 MULTIDISCIPLINARY SCIENCES 6 / 71 = 0.085 2019 Q1 T1 5.569 2019 Biochemistry, Genetics and Molecular Biology (miscellaneous) 2019 Q1 Physics and Astronomy (miscellaneous) 2019 Q1 Chemistry (miscellaneous) 2019 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Korytar, Richard Piantek, Marten Robles, Roberto Lorente, Nicolás Pascual, José I.
