By considering correlations between classical orbits we derive semiclassical expressions for the
decay of the quantum fidelity amplitude for classically chaotic quantum systems, as well as for its
squared modulus, the fidelity or Loschmidt echo. Our semiclassical results for the fidelity amplitude
agree with random matrix theory (RMT) and supersymmetry predictions in the universal ...
