Bound state of dimers on a spherical surface
M. K. Kostov, E. S. Hernandez, M. W. Cole
The study of particle motion on spherical surfaces is relevant to adsorption on buckyballs and other solid particles. This paper reports results for the binding energy of such dime…
Bound states of 3He at the edge of a 4He drop on a cesium surface
R. Mayol, M. Barranco, E. S. Hernandez +2
We show that small amounts of 3He atoms, added to a 4He drop deposited on a flat cesium surface at zero temperature, populate bound states localized at the contact line. These edge…
From nonwetting to prewetting: the asymptotic behavior of 4He drops on alkali substrates
M. Barranco, M. Guilleumas, E. S. Hernandez +3
We investigate the spreading of 4He droplets on alkali surfaces at zero temperature, within the frame of Finite Range Density Functional theory. The equilibrium configurations of s…
Zero sound density oscillations in Fermi-Bose mixtures
P. Capuzzi, E. S. Hernandez
Within a mean field plus Random-Phase Approximation formalism, we investigate the collective excitations of a three component Fermi-Bose mixture of K atoms, magnetically trapped an…
Collisionless collective modes of fermions in magnetic traps
P. Capuzzi, E. S. Hernandez
We present a Random-Phase-Approximation formalism for the collective spectrum of two hyperfine species of dilute 40K atoms, magnetically trapped at zero temperature and subjected t…
Barrier effects on the collective excitations of split Bose-Einstein condensates
P. Capuzzi, E. S. Hernandez
We investigate the collective excitations of a single-species Bose gas at T=0 in a harmonic trap where the confinement undergoes some splitting along one spatial direction. We most…
