A Fuzzy Dark Matter (FDM) halo consists of a soliton core close to the center and an NFW-like density profile in the outer region. Previous investigations found that the soliton core exhibits temporal oscillations and random walk excursions around the halo center. Analyzing a set of numerical simulations, we show that both phenomena can be understood as the results of wave interference -- a suitable superposition of the ground (solitonic) state and excited states in a fixed potential suffices to account for the main features of these phenomena. Such an eigenmode analysis can shed light on the evolution of a satellite halo undergoing tidal disruption. As the outer halo is stripped away, reducing the amplitudes of the excited states, the ground state evolves adiabatically. This suggests diminished soliton oscillations and random walk excursions, an effect to consider in deducing constraints from stellar heating.

Stone Skipping Black Holes in Ultralight Dark Matter Solitons
Black holes in ultralight dark matter solitons undergo quasi-periodic stone-skipping orbits driven by soliton dipole excitations, modifying inspiral dynamics when the black hole is much lighter than the soliton.

Generating Moving Field Initial Conditions with Spatially Varying Boost
A 'spatially varying boost' algorithm assigns arbitrary, position-dependent bulk velocities to field initial data by composing local Lorentz boosts, demonstrated on solitons, Proca fields, and spin-1 wave dark matter.

Vortex-reconnection energy bounds in Bose-Einstein-condensed and superfluid dark matter halos
Vortex reconnections in BEC/superfluid dark matter halos produce dark-sector heating at a rate that is secular but sub-virial for relaxed non-interacting soliton cores, with the dominant uncertainty being the true vor...
