Quantum to classical transport transition and a decoherence detection method in driven optical lattices

Abstract: Atomic quantum systems such as atomic clocks or qubits with cold atoms in tweezer arrays have attracted enormous interests both in academia and industry. In this work, we report a theoretical study and experimental demonstration of quantum tunneling of atoms in 1D optical lattices with decoherence. In such decoherence process, the expansion of atomic wave packet is suppressed and resonance spectrum is broadened. In this regime, as the decoherence rate L or the modulation time t increases, the evolution of atomic wave packets transitions from coherent tunneling to classical diffusion. We propose a detection method to fast evaluate the degree of decoherence in such systems. Our work benefits the study of decoherence properties of precision measurements based on optical lattice.
