Query: The Anomalous Transport of Tracers in Active Baths   We derive the exact long-time dynamics of a tracer immersed in a
one-dimensional active bath. In contrast to previous studies, we find that the
damping and noise correlations possess long-time tails with exponents that
depend on the tracer symmetry. For an asymmetric tracer, the tails lead to
superdiffusion and friction that grows with time when the tracer is dragged at
a constant speed. For a symmetric tracer, we recover normal diffusion and
finite friction. However, when the symmetric tracer is small compared to the
active-particle persistence length, the noise becomes anticorrelated at late
times, and the active contribution to the friction becomes negative: active
particles then enhance motion rather than opposing it.
