Phys. Rev. Lett. 80, 5520–5523 (1998)Time-Dependent Thomas-Fermi Approach for Electron Dynamics in Metal ClustersReceived 23 May 1997; revised 3 November 1997; published in the issue dated 22 June 1998 We propose a time-dependent Thomas-Fermi approach to the (nonlinear) dynamics of many-fermion systems. The approach relies on a hydrodynamical picture describing the system in terms of collective flow. We investigate in particular an application to electron dynamics in metal clusters. We make extensive comparisons with fully fledged quantal dynamical calculations and find overall good agreement. The approach thus provides a reliable and inexpensive scheme to study the electronic response of large metal clusters. © 1998 The American Physical Society URL:
