Gold in graphene: in-plane adsorption and diffusion
S. Malola, H. Häkkinen, P. Koskinen
We study the bonding and diffusion of Au in graphene vacancies using density-functional theory. Energetics show that Au adsorbs preferably to double vacancies, steadily in-plane wi…
A Hot Cavity Laser Ion Source at IGISOL
M. Reponen, T. Kessler, I. D. Moore +2
A development program is underway at the IGISOL (Ion Guide Isotope Separator On-Line) facility, University of Jyvaskyla, to efficiently and selectively produce low-energy radioacti…
Kinetic theory for scalar fields with nonlocal quantum coherence
Matti Herranen, Kimmo Kainulainen, Pyry Matti Rahkila
We derive quantum kinetic equations for scalar fields undergoing coherent evolution either in time (coherent particle production) or in space (quantum reflection). Our central find…
Search for Fingerprints of Tetrahedral Symmetry in
Q. T. Doan, D. Curien, O. Stezowski +28
Theoretical predictions suggest the presence of tetrahedral symmetry as an explanation for the vanishing intra-band E2-transitions at the bottom of the odd-spin negative parity ban…
Solutions of Aronsson equation near isolated points
Vesa Julin
We show that for non-negative solution of the Aronsson equation an isolated singularity is either removable, or the solution behaves asymptotically like a general cone. This genera…
Shell-structure fingerprints of tensor interaction
M. Zalewski, W. Satula, J. Dobaczewski +4
We address consequences of strong tensor and weak spin-orbit terms in the local energy density functional, resulting from fits to the splittings in Ca, $…
