New Update of the FPLO program package

29.04.2014

The Leibniz-Institute for Solid State and Material Sciences (IFW) Dresden published an updated version of their program package for the calculation of electronic structures.

The density functional theory is an important method to calculate quantum mechanical properties of atoms, molecules, and solids.

Its development and utilization was awarded with the Nobel prize in chemistry for Walter Kohn and John Pople in 1998. Using the density functional theory one can evaluate, for example, chemical binding energies and optical spectra as well as mechanical, electric, and magnetic properties of materials.

In this way it is possible to predict material specific properties or to explain related experimental findings solely from the chemical composition and the atomistic structure of the material.

The required numerical schemes have to solve implicit, non-linear integro-differential systems of equations, developed by Walter Kohn and other authors. Such schemes are being developed world-wide using several competing methods of resolution with specific advantages and shortcomings.

One of these numerical schemes has been developed by Dr. Klaus Koepernik at the Leibniz-Institute for Solid State and Material Sciences (IFW) Dresden since 1999. Its name FPLO© stands for Full-Potential, Local-Orbital; its advantages consist in a balanced combination of high numerical precision with efficiency and in its easy handling.

The advantage of an in-house development, as carried out at IFW, mainly consists in the possibility to quickly implement new features satisfying emerging research needs.

The FPLO© package comprises about 300,000 lines of code and has about 200 licensed users worldwide.

A new version of this package was released at the end of March, 2014. Details can be found at http://www.fplo.de/.

The development of electron theory and related methods in Dresden started in the 1950ies and is connected with the names of W. Macke, P. Ziesche, and H. Eschrig, the founding director of the IFW,

Im Focus: Nuclear Pores Captured on Film

Using an ultra fast-scanning atomic force microscope, a team of researchers from the University of Basel has filmed “living” nuclear pore complexes at work for the first time. Nuclear pores are molecular machines that control the traffic entering or exiting the cell nucleus. In their article published in Nature Nanotechnology, the researchers explain how the passage of unwanted molecules is prevented by rapidly moving molecular “tentacles” inside the pore.

Using high-speed AFM, Roderick Lim, Argovia Professor at the Biozentrum and the Swiss Nanoscience Institute of the University of Basel, has not only directly...

Im Focus: 2+1 is Not Always 3 - In the microworld unity is not always strength

If a person pushes a broken-down car alone, there is a certain effect. If another person helps, the result is the sum of their efforts. If two micro-particles are pushing another microparticle, however, the resulting effect may not necessarily be the sum their efforts. A recent study published in Nature Communications, measured this odd effect that scientists call “many body.”

In the microscopic world, where the modern miniaturized machines at the new frontiers of technology operate, as long as we are in the presence of two...

Im Focus: Tiny microbots that can clean up water

Researchers from the Max Planck Institute Stuttgart have developed self-propelled tiny ‘microbots’ that can remove lead or organic pollution from contaminated water.

Working with colleagues in Barcelona and Singapore, Samuel Sánchez’s group used graphene oxide to make their microscale motors, which are able to adsorb lead...

Im Focus: ORNL researchers discover new state of water molecule

Neutron scattering and computational modeling have revealed unique and unexpected behavior of water molecules under extreme confinement that is unmatched by any known gas, liquid or solid states.

In a paper published in Physical Review Letters, researchers at the Department of Energy's Oak Ridge National Laboratory describe a new tunneling state of...
