• I consider a Brownian particle immersed in a one-dimensional boson gas with delta-function repulsive potentials. I find many-body complex eigenvalues of the Liouville superoperator, up to second order in the coupling constant. The eigenvalues give the diffusion time-scale of the Brownian particle. The eigenvalue problem is solved using a Bethe-ansatz approach.
