Collectivity in the optical response of small metal clusters
The question whether the linear absorption spectra of metal clusters can be interpreted as density oscillations (collective “plasmons”) or can only be understood as transitions between distinct molecular states is still a matter of debate for clusters with only a few electrons. We calculate the photoabsorption spectra of Na2 and Na5 comparing two different methods: quantum fluid-dynamics and ti...
متن کاملOptical response of small magnesium clusters
We predict the strong enhancement in the photoabsorption of small Mg clusters in the region of 4-5 eV due to the resonant excitation of the plasmon oscillations of cluster electrons. The photoabsorption spectra for neutral Mg clusters consisting of up to N = 11 atoms have been calculated using ab initio framework based on the time dependent density functional theory (TDDFT). The nature of predi...
متن کاملOptical response of small silver clusters
The time-dependent local density approximation is applied to the optical response of the silver clusters, Ag2, Ag3, Ag8 and Ag9 . The calculation includes all the electrons beyond the closed-shell Ag+11 ionic core, thus including for the first time explicitly the filled d-shell in the response. The excitation energy of the strong surface plasmon near 4 eV agrees well with experiment. The theore...
متن کاملOptical response of small carbon clusters
We apply the time-dependent local density approximation (TDLDA) to calculate dipole excitations in small carbon clusters. A strong low-frequency mode is found which agrees well with observation for clusters Cn with n in the range 7 − 15. The size dependence of the mode may be understood simply as the classical resonance of electrons in a conducting needle. For a ring geometry, the lowest collec...
متن کاملTemperature Dependence of the Optical Response of Small Sodium Clusters
We present an analysis of the temperature dependence of the optical response of small sodium clusters in a temperature range bracketing the melting phase transition. When the temperature increases, the mean excitation energy undergoes a red shift and the plasmon is significantly broadened, in agreement with recent experimental data. We show that the single–particle levels acquire a prominent wi...
