improved - The FockState class has been completely reworked, now much
more efficient in how it stores data and steps to the next label. Also
it is now Iterable, essential FockState-looping!
init - the Interaction enum class was added for easily choosing type of
interaction wanted in a simulation.
init - the FreeHamiltonian is essentially an object which keeps track of
the energies of the free theory. Storing as a buffer because it would be
inefficient to recalculate energies at every time step.
improved - the QFTSandbox graphical application now includes Fourier
transforms. Plot and DensityPlot can now also take in Complex numbers
(shows the mod square).
improved - [IMPORTANT MILESTONE] the InteractionHamiltonian can now
actually calculates all the elements, and does so reasonably
efficiently. There are many improvements (major changes) that can and
will be done.
improved - the QuantumState has minor changes to accompany the now
working InteractionHamiltonian.
moved - the qft.test-package was moved to the
qft.interactingtheory.test-package. Tests were added for relevant
classes.
