Physics Projects from the Technion

NEW PROJECTS - see here.

Projects since 2005 are not yet integrated in the list below and can be viewed by year:
[2005] [ 2006] [2007] [2009] [2010] [2011] [2012] [2014] [in progress 2013]

This is an edited subset of projects prepared in the Physics Department at the Technion, in 1997-2005. Some were prepared as final undergraduate projects, some with grants from the Technion Center for the Promotion of Teaching, and most thru the course Introduction to Computational Physics taught by Joan Adler.

The projects are classfied by subject so some projects may be listed more than once. Emails and links to homepages of the students who prepared the projects are given for each project, but since good students tend to graduate after a finite time, feel free to contact Joan Adler if these links are outdated. In some cases there are links to archival material as well as the students' personal site.

WARNING: All the websites and the mpgs and animated gifs from the sites should run on any browser - netscape (4 and above), explorer etc, BUT while all the downloadable software linked here runs in a UNIX environment (definitely LINUX and SOLARIS and probably others) and the MATLAB and MATHEMATICA codes will also run in a microsoft environment, the other software and particularly the visualization tools such as PGPLOT (not public domain but free for non-commercial use) and AViz (public domain) would require adaptation for microsoft windows. The reason for LINUX is to make software both free and legal.

All projects are presented `as is' and we hope they are useful to others but do not promise support or assistance in running the software. Help with the software might be found on the Computational Physics Course pages. For users outside the Technion, some additional notes on the software used are at the bottom of this page.

The first one has been written in C++ and has been compiled by Visual Studio. The next two have been written in FORTRAN, where the WINDOWS version has been compiled by the g77 compiler for WINDOWS and the UNIX version has been compiled by f77 (located on the phclass1 server). The last program is a FORTRAN code that can be changed and compiled in both DOS/UNIX systems.

    If you need help contacting the students who prepared the software, please contact Joan Adler but if you experience problems running the software once you have it PLEASE READ THIS BEFORE asking for more help. The projects all execute with either public domain software or with software site licensed within the Mahba /Technion environment. Computers mentioned by name include tx.technion.ac.il (solaris) phelafel (linux) minerva1 (AIX) and mtwolfson (SG). If software is listed on the http server phjoan12.technion.ac.il/pub it was moved to the http server phjoan23.technion.ac.il/old_pub when phjoan12 was retired. If you need help with Matlab, IMSL or PGPLOT you can try the Technion Computer Consultants publications website or the consultants at your own institution. For AViz help contact Joan Adler whatever because although it is public domain software it was prepared by the Technion Computational Physics group and we are happy to help on this.

    It is hard to remember to list all the people who helped with these projects but a partial list includes my teaching assistants, Amihai Silverman, Sasha Berengoltz and Adham Hashibon, my other graduate students David Saada, Zaher Salman, Slava and Anastasia Sorkin, Oren Hershkovitz, Nir Schreiber, many of the project creators who helped later students, my postdocs Geri Wagner and Irena Rosenblum, Physics Department software engineer Riva Kreiselman, and the faculty members who proposed projects, especially Bertina Fisher, Steve Lipson and Erez Ribak. The Technion Computer Center consultants, especially Batia Perry and Moshe Goldberg have provided constant wonderful support for me and the students. Lastly, thanks to Jimmy Nishry and Israel ben Efraim for supporting the classroom development for the Computational Physics classroom.
