      abstract     = {Nonlinear effects in particle accelerators have
                      historically been treated as harmful influences that
                      necessitate various mitigation schemes. Therefore, the
                      simulation tools available are largely focused on
                      identifying and correcting resonances. However, recent
                      advances proved that nonlinear beam dynamics enables new
                      techniques for manipulating particle beams and can
                      characterise diffusion and chaos in particle accelerators.
                      The simulation tools currently available for these purposes
                      are difficult to integrate across different frameworks. This
                      paper presents Xnlbd, a new Python package extending the
                      Xsuite simulation framework, which aims to provide a unified
                      set of tools for analysing nonlinear beam dynamics
                      phenomena. It allows the visualisation of highly nonlinear
                      phase spaces, the efficient finding of both stable and
                      unstable fixed points and separatrices, the calculation of
                      resonance driving terms and normal forms, and the
                      computation of dynamic indicators for the detection of
                      chaotic motion.},
