    "abstract": "We theoretically study the effects of elastic collisions on the determination\nof frequency standards via Ramsey fringe spectroscopy in optical-lattice atom\nclocks. Interparticle interactions of bosonic atoms in multiply-occupied\nlattice sites can cause a linear frequency shift, as well as generate\nasymmetric Ramsey fringe patterns and reduce fringe visibility due to\ninterparticle entanglement. We propose a method of reducing these collisional\neffects in an optical lattice by introducing a phase difference of $\\pi$\nbetween the Ramsey driving fields in adjacent sites. This configuration\nsuppresses site to site hopping due to interference of two tunneling pathways,\nwithout degrading fringe visibility. Consequently, the probability of double\noccupancy is reduced, leading to cancellation of collisional shifts.",
