Query: Aperiodic and linearly repetitive Lorentz gases of finite horizon are
  not exponentially mixing   We prove that aperiodic and linearly repetitive Lorentz gases with finite
horizon are not mixing with exponential or stretched exponential speed in any
dimension for any class of H\"older observables. We also bound the polynomial
speed of mixing for observables in the H\"older space $H_{\alpha}$ depending on
$\alpha$.
