We investigate the spreading of 4 He droplets on alkali surfaces at zero temperature, within the frame of Finite Range Density Functional theory. The equilibrium configurations of several 4 He N clusters and their asymptotic trend with increasing particle number N , which can be traced to the wetting behavior of the quantum fluid, are examined for nanoscopic droplets. We discuss the size effect...

We investigate the electronic structure of the beryllium atom subjected to a strong magnetic field in the regime 0 ≤ γ ≤ 10 a.u. The ground as well as many excited states of spin singlet, triplet and quintet multiplicity covering the magnetic quantum numbers |M | = 0, 1, 3, 6 for both positive and negative z−parity are discussed and analyzed. Total and one-particle ionization energies are prese...

We study the shearing of polydisperse and bidisperse media with a size ratio of 10. Simulations are performed with a the two dimensional shear cell using contact dynamics. With a truncated power law for the polydisperse media we find that they show a stronger dilatancy and greater resistance to shearing than bidisperse mixtures. Motivated by the practical problem of reducing the energy needed t...
