Three real-space discretization techniques in electronic structure calculations
T. Torsti, T. Eirola, J. Enkovaara +13
A characteristic feature of the state-of-the-art of real-space methods in electronic structure calculations is the diversity of the techniques used in the discretization of the rel…
Model study of adsorbed metallic quantum dots: Na on Cu(111)
T. Torsti, V. Lindberg, M. J. Puska +1
We model electronic properties of the second monolayer Na adatom islands (quantum dots) on the Cu(111) surface covered homogeneously by the first Na monolayer. An axially-symmetric…
Electronic resonance states in metallic nanowires during the breaking process simulated with the ultimate jellium model
E. Ogando, T. Torsti, N. Zabala +1
We investigate the elongation and breaking process of metallic nanowires using the ultimate jellium model in self-consistent density-functional calculations of the electron structu…
MIKA: a multigrid-based program package for electronic structure calculations
T. Torsti, M. Heiskanen, M. J. Puska +1
A general real-space multigrid algorithm MIKA (Multigrid Instead of the K-spAce) for the self-consistent solution of the Kohn-Sham equations appearing in the state-of-the-art elect…
Conductance oscillations in metallic nanocontacts
P. Havu, T. Torsti, M. J. Puska +1
We examine the conductance properties of a chain of Na atoms between two metallic leads in the limit of low bias. Resonant states corresponding to the conductance channel and the l…
A novel multigrid method for electronic structure calculations
M. Heiskanen, T. Torsti, M. J. Puska +1
A general real-space multigrid algorithm for the self-consistent solution of the Kohn-Sham equations appearing in the state-of-the-art electronic-structure calculations is describe…
