Density Functional Theory of doped superfluid liquid helium and nanodroplets
Francesco Ancilotto, Manuel Barranco, Francois Coppens +5
During the last decade, density function theory (DFT) in its static and dynamic time dependent forms, has emerged as a powerful tool to describe the structure and dynamics of doped…
Correlations in the low-density Fermi gas: Fermi-Liquid state, Dimerization, and BCS Pairing
H. H. Fan, E. Krotscheck, T. Lichtenegger +2
We present ground state calculations for low-density Fermi gases described by two model interactions, an attractive square-well potential and a Lennard-Jones potential, of varying…
Desorption Dynamics of Heavy Alkali Metal Atoms (Rb, Cs) off the Surface of Helium Nanodroplets
J. von Vangerow, A. Sieg, F. Stienkemeier +6
We present a combined ion imaging and density functional theory study of the dynamics of the desorption process of rubidium and cesium atoms off the surface of helium nanodroplets…
Solvation of Intrinsic Positive Charge in Superfluid Helium
David Mateo, Jussi Eloranta
Based on electronic structure calculations, the structure of intrinsic positive charge solvated in superfluid helium is identified as triatomic He3^+ ion, which is bound to the sur…
Mg impurity in helium droplets
J. Navarro, D. Mateo, M. Barranco +1
Within the diffusion Monte Carlo approach, we have determined the structure of isotopically pure and mixed helium droplets doped with one magnesium atom. For pure 4He clusters, our…
Excited electron-bubble states in superfluid helium-4: a time-dependent density functional approach
David Mateo, Dafei Jin, Manuel Barranco +1
We present a systematic study on the excited electron-bubble states in superfluid helium-4 using a time-dependent density functional approach. For the evolution of the 1P bubble st…
Evolution of the excited electron bubble in liquid 4He and the appearance of fission-like processes
David Mateo, Martí Pi, Manuel Barranco
We have studied the evolution of an excited electron bubble in superfluid 4He for several tens of picoseconds combining the dynamics of the liquid with an adiabatic evolution for t…
Ca impurity in small mixed He-He clusters
R. Guardiola, J. Navarro, D. Mateo +1
The structure of small mixed helium clusters doped with one calcium atom has been determined within the diffusion Monte Carlo framework. The results show that the calcium atom sits…
