Abstract
In this thesis, I use the Bethe Ansatz (BA) to study various one-dimensional
models. I first go through some background on the BA (both the coordinate
and algebraic forms). I start the study by using the BA to compare bound
state occurrences between the 2-particle XXZ, Bose–Hubbard, and Fermi–
Hubbard models. In the next chapter, I introduce ‘quenches’ and use the
BA in order to calculate quench overlaps in the Lieb–Liniger model. In the
final chapter, I introduce the spatial von Neumann bipartite entanglement
entropy and use the BA in order to calculate this entropy in the Lieb–Liniger
model.
