Intra- and interband excitations induced residue decay of the Bose polaron in a one-dimensional double-well
We investigate the polaronic properties of a single impurity immersed in a weakly interacting bosonic environment confined within a one-dimensional double-well potential using an exact diagonalization approach. We find that an increase of the impurity–bath coupling results in a vanishing residue, si...
