About
We introduce a model-independent method for preparing and detecting quasiparticle wavepackets in (quasi-)1D quantum many-body systems. We exploit maximally localized Wannier functions obtained from exact diagonalization to construct unitary quasiparticle creation operators. These can then be applied to larger systems, encoded using tensor networks or quantum simulators. Detection further distinguishes single-particle contributions from resonances. We benchmark the method in real-time matrix-product-state simulations of glueball-glueball scattering in a truncated SU(3) gauge theory on a ladder. By encoding the model in a qutrit chain, we provide a minimal setup for studying dynamical pure-gauge excitations.
