Please add/comment on the strength and weaknesses of Wien 2K and add/comment on proposed features of the new system (flair/gem) described below.

Senior undergraduates in physics will also find the course accessible. Topics include the theoretical basis of the electronic structure of solids, viewed from the real-space perspective of the interactions between atoms; the free electron desc… text/html 2020-03-06T09:12:52+00:00 Anonymous (anonymous@undisclosed.example.com) https://sites.science.oregonstate.edu/~tatej/COURSES/ph575/doku.php?id=links&rev=1583514772&do=diff Useful Links Journals These are direct links to several journals. If you can link to them also through the OSU Library Proxy Server, you will have free access to all articles (ONID login required from off campus).

You will use the software package OpenMX to calculate the band structure of a semiconductor, metal, or insulator. You can complement your own calculations by downloading band structures from an open source project called aflow.

When all else fails ... a.k.a. “I'm doing everything right, but it still messes up” .. Wien is modular - it's the weakness and the strength - and sometimes it just takes too long to figure out which file has been overwritten by what process. Start again in a completely new folder.
