Título: | Towards a description of the Kondo effect using time-dependent density-functional theory |
Autor: | Stefanucci, Gianluca; Kurth, S. CSIC ORCID | Fecha de publicación: | 2011 | Editor: | American Physical Society | Citación: | Physical Review Letters 107(21): 216401 (2011) | Resumen: | We demonstrate that the zero-temperature conductance of the Anderson model can be calculated within the Landauer formalism combined with static density-functional theory. The proposed approximate functional is based on finite-temperature density-functional theory and yields the exact Kohn-Sham potential at the particle-hole symmetric point. Furthermore, in the limit of zero temperature it correctly exhibits a derivative discontinuity which is shown to be essential to reproduce the conductance plateau. On the other hand, at the Kondo temperature the exact Kohn-Sham conductance overestimates the real one by an order of magnitude. To understand the failure of density-functional theory, we resort to its time-dependent version and conclude that the suppression of the Kondo resonance must be attributed to dynamical exchange-correlation corrections. © 2011 American Physical Society. | Versión del editor: | http://dx.doi.org/10.1103/PhysRevLett.107.216401 | URI: | http://hdl.handle.net/10261/50916 | DOI: | 10.1103/PhysRevLett.107.216401 | Identificadores: | doi: 10.1103/PhysRevLett.107.216401 issn: 0031-9007 |
