Class | Description |
---|---|
CachedFunction |
A univariate real function that caches previous evaluations,
so that they can be returned faster if the function is evaluated
at the same point several times.
|
FreeModel |
The free model is a trivial example of an integrable model with
scattering function S=1.
|
IntegrableModel |
An integrable model of quantum field theory with one species of scalar particle.
|
IsingModel |
The Ising model is an integrable model with constant scattering function S=-1.
|
ProductModel |
An integrable model with scattering function composed of the product of several sinh-Gordon scattering functions.
|
ProductModelTest |
Unit tests for the ProductModel class.
|
SinhGordonModel |
The sinh-Gordon model with coupling \( 0 < B < 2 \).
|
SinhIsingModel |
The "sinh-Ising model" is an amalgamation of the sinh-Gordon and the Ising models.
|
SinhTools |
This class provides helper functionality for computing the minimal solutions
of various models, given by the exponential of a certain integral expression.
|
SinhToolsTest |
Unit tests for the
SinhTools class. |

.
Their only property of interest to us in the present context is the function \(\theta \mapsto F_\mathrm{min}(\theta+i\pi)\).
In some cases, such as the Ising model, this expression can be computed directly from elementary functions,
whereas for the sinh-Gordon and related models, this involves numerical approximation of an integral.
