Using the Wick theorem for Hubbard operators, we generate the linked-cluster expansion around the atomic limit of the Hubbard model and use it to calculate the free energy, ...

This Mathematica notebook contains the code used to generate the figures in the article "Exploring Localization in Nonperiodic Systems" which appears in the June 1995 issue ...

This package adds ExtendedLatticeReduce, GramLatticeReduce, and LatticeReducedQ, to the builtin function LatticeReduce. ExtendedLatticeReduce does not just give a reduced ...

Tools are presented that provide facilities of Mathematica Notebooks in a UNIX environment under GNU Emacs. They permit interaction between a text and a Mathematica buffer ...

Foreign book: Hungarian (*English translation included side-by-side with Hungarian). Collection of about 1,000 graphics. Mathematical principles were used to generate them. ...

The StackedGraphicsArray package provides an extension to GraphicsArray. It generates an array of framed plots with "shared" axes and no spacing between the framed plots. ...

The action of Möbius transformations with real coefficients preserves the hyperbolic metric in the upper half-plane model of the hyperbolic plane. The modular group is an ...

Optimum lens shape can easily be found by an evolutionary algorithm. The algorithm generates new values (children) for the d-i by varying the starting values (parents) ...

nVizx enables Mathematica users to rapidly generate dynamic, high resolution 3D objects and scenes in precise detail on a typical Windows personal computer. Interactive ...

This notebook (among other things) generates periodic tables from variable data (the data and layout can be changed for a particular subject's use). This chart is neat, ...
