Special features of "ising"

You may also want to look at the full parameter list of all the buttons and sliders, or at one of the general help files, Sliders, or Graphs.

Key equivalents

• run/stop; press the spacebar.
• init. Use the i-key or select an item from the initial conditions menu.

Miscellaneous

• Spins may be manually flipped by clicking on them or by slowly dragging the cursor across them. This can be useful in designing your own initial conditions which may then be stored and recalled
• Note that the temperature and magnetic field are expressed NOT in kelvin and tesla, but in dimensionless units relative to the nearest neighbor exchange energy J. This, of course, is the natural language for the computer. Similarly, "ising" works with a normalized magnetization, the ratio of the actual magnetization to its maximum possible, or saturation value.
• The first point (at zero sweeps) on the graph will be whatever is in memory when the reset button is clicked. If you care about the first point on the graph, click reset AFTER you set the initial conditions.
