Henning Bostelmann, Daniela Cadamuro: Negative energy densities in integrable quantum field theories at one-particle level

This computer code was used to generate the graphics used in the article. It computes the lowest eigenvalues and eigenvectors of the smeared energy density \(T^{00}(g^2)\) with various choices of integrable models and of other parameters.

The code is structured into three parts (packages): {@link models} deals with the properties of the various integrable models, in particular their function \(F_\mathrm{min}\). {@link kernels} instead computes the integral kernel for the smeared energy density, given an integrable model. It also deals with discretization of the kernel and finding its eigendecompostion. {@link cli} contains command-line applications that run the computation for various sets of input parameters, and generate the data used in the graphs in the paper.

The code is written in Java (version 6 onwards) and requires the following libraries:
