We Investigate The Crossover Of The Impurity-Induced Dynamics, In Trapped One-Dimensional Bose Polarons Subject To Radio Frequency (RF) Pulses Of Varying Intensity, From An Adiabatic To A Diabatic Regime. Utilizing Adiabatic Pulses For Either Weak Repulsive Or Attractive Impurity-Medium Interactions, A Multitude Of Polaronic Excitations Or Mode-Couplings Of The Impurity-Bath Interaction With The Collective Breathing Motion Of The Bosonic Medium Are Spectrally Resolved. We Find That For Strongly Repulsive Impurity-Bath Interactions, A Temporal Orthogonality Catastrophe Manifests In Resonances In The Excitation Spectra Where Impurity Coherence Vanishes. When Two Impurities Are Introduced, Impurity-Impurity Correlations, For Either Attractive Or Strong Repulsive Couplings, …
