      abstract     = {The conformational and dynamical properties of a passive
                      polymer embedded in a bath of active Brownian particles
                      (ABPs) are studied by Langevin dynamics simulations. Various
                      activities and ABP concentrations below and above the
                      critical values for motility-induced phase separation (MIPS)
                      are considered. In a homogeneous ABP fluid, the embedded
                      polymer swells with increasing bath activity, with stronger
                      swelling for larger densities. The polymer dynamics is
                      enhanced, with the diffusion coefficient increasing by a
                      power-law with increasing activity, where the exponent
                      depends on the ABP concentration. For ABP concentrations in
                      the MIPS regime, we observe a localization of the polymer in
                      the low-density ABP phase associated with polymer collapse
                      for moderate activities and a reswelling for high activities
                      accom- panied by a preferred localization in the
                      high-density ABP phase. Localization and reswelling are
                      independent of the polymer stiffness, with stiff polymers
                      behaving similarly to flexible polymers. The polymer
                      collapse is associated with a slowdown of its dynamics and a
                      significantly smaller center-of-mass diffusion coefficient.
                      In general, the polymer dynamics can only partially be
                      described by an effective (bath) tempera- ture. Moreover,
                      the properties of a polymer embedded in a homogeneous active
                      bath deviate quantitatively from those of a polymer composed
                      of active monomers, i.e., linear chains of ABPs; however,
                      such a polymer exhibits qualitatively similar
                      activity-dependent features.},
