UnOfficial Wire Mod

This is a quantum simulation program from the Shumway Research Group, which focuses on applications to nanoscience and technology. Path integral Monte Carlo (PIMC) simulates particles (often electrons ... [More] and ions) by directly sampling the canonical partition function. In the path integral formulation of quantum statistical mechanics developed by Richard Feynman, particles get represented by closed imaginary-time trajectories of length ℏ/kT. PIMC simulations are able to compute total energies, correlation functions, charge distribution, and linear response functions for thermal equilibrium. As in many quantum Monte Carlo methods, PIMC has efficient scaling with system size, often order N2 or N3. Our application, pi or pi-qmc, is well suited for modeling conduction electrons and holes in quantum dots, quantum wires, and quantum wells. For quantum dots and wires, we often generate realistic confining potentials using qdot-tools. We are also testing and developing pi for ab initio calculations, but at this point only hydrogen and helium systems work well. To get started: To download the code, the subversion repository (“Source” tab) has the latest version. This is an active research code, so all versions are development (beta), and we highly recommend using the subversion server for easy updates. See the wiki page on how to build the pi code. There is an overview of PIMC on the wiki (in progress). There is a list of current applications on the wiki (in progress). To test out pi without downloading or installing anything, try out the online nanoHUB tool. Please send me your feedback: john.shumway@asu.edu. This is my group's primary research code. Most of my efforts go towards our group research needs and collaborative science projects, but I'm making this code public to help everyone. Path integrals are fun, and I think a lot of interesting research can be enabled with some cooperation. I like to hear from other scientists, either via email or on the issues page. Instructional or tutorial material is much easier to justify if people document their interests. New developers are welcome to join this project. [Less]

This is a collection of nanostructure simulation and modeling programs for self assembled quantum dots and other nanostructures. Atomic Nanostructure Layout Code: geomThis program, geom, is a simple ... [More] utility for turning nanostructure descriptions into atomic layout. These atomic positions are common input for several types of quantum dot models, such as tight-binding or empirical pseudopotentials. The user specifies the size, shape, and composition of a coherent III-V or group IV semiconductor heterostructure. Shapes include lens, pyramidal, and conical dots, as well as quantum wells, and may be filled with different alloy or pure materials. Output is an HDF5 file, struct.h5, containing atom positions, chemical identities, lattice indexing, and neighbor tables. The object-oriented design makes it easy for users to add new shapes and materials to this utility. Libraries used: HDF5, libxml2 Strain Relaxation Code: relaxThis program, relax, uses a conjugate-gradient algorithm to relax atomic positions in coherently strained semiconductor nanostructures. A typical simulation of millions of atoms in and around an embeded quantum dot runs in a few hours on a typical PC. Input is an HDF5 file, struct.h5, containing the atomic positions, identities, and neighbor tables. The program output, relaxed.h5, is the relaxed atomic positions in the same HDF5 format as the input file, suitable for input into an atomistic electronic structure model. Also calculates stress for each atom. Libraries used: HDF5, libxml2, blitz Effective Mass Model Generator: getemaThis program, getema, extracts an effective mass model boffset.h5 from a relaxed nanostructure relaxed,h5. The strained band offsets in boffset.h5 can be used as input to our pi path integral quantum Monte Carlo code. Libraries used: HDF5, libxml2, blitz [Less]

IntroductionThis is my compilation of GMod addons that I use. If you come to my server, you may want this. What's in it?Wire, Advanced Duplicator, PCMod, Phoenix Storms 3, simple-admin, ezpose, and ... [More] Fake Factory CM4 to name a few. Do the authors care that you are using their models?I hope not. My main intention if only for people to be able to use what I'm using, so they can visit my servers error free. [Less]
