STATIC: About Version 1.10

Version 1.10

Version 1.10 of static has the following features:

• A script file skingen, written in Perl, can be used to set up much of the required input.
• Included support for Gillan's T->0 extrapolation of Fermi Temperature Broadening [M.J. Gillan, J. Phys. Condes. Matter 1, 689-711 (1989)]. Gillan assumes his correction has a T³ behavior. However, Grotheer and Fahnle [Phys. Rev. B 58, 13459-64 (1998)] argue convincingly that the correction actually goes as T⁴, and I have been able to show this is true exactly if we don't have to worry about (a) self-consistency, and (b) a nearby van Hove singularity (i.e., we can do a Taylor expansion of the density of states in a region of order T around the Fermi level).
• Include a new mode which allows the eigenvalue decomposition information to be stored in unformatted Fortran form. This allows the information to be stored more compactly and to a higher precision.
• Revised the "phonon" mode in input1.f. Now we can shift any individual atom away from its input position, using either Cartesian or lattice coordinates. This is useful if we want to move only a few atoms away from equilibrium.

An intermediate release, Version 1.06, made several changes in the code which saved a considerable amount of memory. Other changes improved the reliability and readability of the program.

For more information, see the file REVISION_HISTORY in the static distribution.

Finally, the distribution of static is password protected. This allows us to more accurately track the users of the program. See Obtaining the Source Code for more information.
