Surface location of sodium atoms attached to He nanodroplets
F. Stienkemeier, O. Bünermann, R. Mayol +3
We have experimentally studied the electronic excitation of Na atoms attached to He droplets by means of laser-induced fluorescence as well as beam depletion…
Nucleation in dilute 3He-4He liquid mixtures at low temperatures
M. Barranco, M. Guilleumas, D. M. Jezek +3
We present a study of phase separation from supersaturated 3He-4He liquid mixtures at low temperatures addressing both the degree of critical supersaturation Dx and the thermal-to-…
Multipole excitations in quantum dots
A. Emperador, M. Barranco, E. Lipparini +2
We have employed time-dependent local-spin density theory to analyze the multipole spin and charge density excitations recently found in GaAs-AlGaAs quatum dots [C. Schüller et al,…
Ring vortex destabilization in supersaturated 3He-4He liquid mixtures at low temperatures
D. M. Jezek, M. Pi, M. Barranco +2
The effect of ring vortices on the destabilization of supersaturated liquid helium mixtures at very low temperatures is investigated as a function of pressure. We have found that l…
