cast vector size immediately to `unsigned int` which is the type needed for the launch configuration. There is still an additional conversion to CUDAs `dim3` vector-type, but its initializer uses `unsigned int`.
This improves readability of the function signature of the constructor. The long term goal is modularizing the Hamiltonian in terms of all of the energy contributions in order to reuse parts for the spin-lattice Hamiltonian.
this structure is commonly used in the Hamiltonian classes to describe the different energy contributions. I gave it a name to make these occurrences more readable.
combine the implementations in `engine/Hamiltonian_Heisenberg.cpp` and `engine/Hamiltonian_Heisenberg.cu` into one, avoiding the code duplication that was present before. This commit should not change any existing behaviour.
The `Hamiltonian_Heisenberg.cpp` file needs to know about the CUDA kernels through a CUDA header. I overlooked that the doubling of pairs also applies to the CUDA build, not just to the OpenMP build.

The step is needed to prepare for modularity. The new interaction files should all be created inside the `engine/interaction` subdirectory.
Lift the splitting of the Hamiltonian class into a `Hamiltonian_Heisenberg` and a `Hamiltonian_Gaussian` in favor of a unified `Hamiltonian` class. The `Gaussian` part will be reintroduced as an Interaction class that is stored inside the new `Hamiltonian` class if needed. The code for this implementation is already present, but the `Gaussian` functionality is neutered in this commit.
Introduces the data structure for storing interactions. It is of type: `std::vector<std::unique_ptr<Engine::Interaction::ABC>>` This vector marks the `Hamiltonian` as the owner of the interactions and necessitates the creation of constructors according to the rule of five. For setting and getting the interactions a set of templated member functions is used which can also be used at run time given the name of the interaction. The Gaussian interaction is not usable with this commit.
Reintroduces the effects of `Interaction::Gaussian` on the Hamiltonian. The current mechanism isn't yet optimal, but designed to interoperate with the old one. Later on the lookups should be replaced by loops and the shape of `energy_contributions_per_spin` is fully determined by the `interactions` vector.
note: There is currently no test for the Anisotropy with a Hamiltonian that is initialized from a config file.
…olated_Energy_Contributions() This simplification is enabled by the modularization of the Hamiltonian. It makes the public accessors for the component indices obsolete.
The default `gcc-11` produces a failing test (`test_physics`) for the single precision build which newer versions of `gcc` don't.
The `test_physics` test case has either a precision issue or a race condition for the dephasing test when compiling with `gcc-12`. This issue isn't present with `gcc-13` and `gcc-14`.
