Antiferromagnetic Ising model applet: simulation in the multicanonical ensemble with the Wang-Landau algorithm |
|

|
Applet help:
- The S(E) chart on the right side displays the estimate of the
microcanonical entropy S(E) in real time.
- The south-panel displays charts of reweighted thermodymical averages as a funtion of temperature.
The "F(kT,E)" button let you visualize the variational free energy. For second-order transitions
(as is the case for the AF Ising model), and near the transition temperature,
you should witness a single clear minimum.
- The "temperature" button let you configure many things regarding the simulation, e.g. temperature range for
the reweighting procedure, number of measurements between checks histogram roughness, ...
- if the applet runs too slowly, reduce the "Latency". If still slow, deselect the "Animate" checkbox.
