    "abstract": "Two types of particles, A and B with their corresponding antiparticles, are\ndefined in a one dimensional cyclic lattice with an odd number of sites. In\neach step of time evolution, each particle acts as a source for the\npolarization field of the other type of particle with nonlocal action but with\nan effect decreasing with the distance: A --\u003e...\\bar{B} B \\bar{B} B \\bar{B} ...\n; B --\u003e A \\bar{A} A \\bar{A} A ... . It is shown that the combined distribution\nof these particles obeys the time evolution of a free particle as given by\nquantum mechanics.",
