Preliminary Design of a Pendulum Experiment for Searching for a   Lorentz-Violation Signal
  This work mainly presents a preliminary design for a pendulum experiment with both the source mass and the test mass in a striped pattern to amplify the Lorentz-violation signal, since the signal is sensitive to edge effects.
