urn:hdl:2445/12797 Pinning of quantized vortices in helium drops by dopant atoms and molecules Dalfovo, Franco Mayol Sánchez, Ricardo Pi Pericay, Martí Barranco Gómez, Manuel Líquids quàntics Química quàntica Macromolècules Quantum fluids Quantum chemistry Macromolecules Using a density functional method, we investigate the properties of liquid 4He droplets doped with atoms (Ne and Xe) and molecules ( SF6 and hydrogen cyanide). We consider the case of droplets having a quantized vortex pinned to the dopant. A liquid-drop formula is proposed that accurately describes the total energy of the complex and allows one to extrapolate the density functional results to large N. For a given impurity, we find that the formation of a dopant+vortex+4HeN complex is energetically favored below a critical size Ncr. Our results support the possibility to observe quantized vortices in helium droplets by means of spectroscopic techniques. 2010-06-08T10:16:37Z 2010-06-08T10:16:37Z 2000 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Reproducció digital del document publicat en format paper, proporcionada per APS i http://dx.doi.org/10.1103/PhysRevLett.85.1028 Physical Review Letters, 2000, vol. 85, núm. 5, p. 1028-1031 http://dx.doi.org/10.1103/PhysRevLett.85.1028 (c) American Physical Society, 2000 info:eu-repo/semantics/openAccess American Physical Society Articles publicats en revistes (Física Quàntica i Astrofísica)
