Studying and Manipulating the Quantum Motion of Atoms in Optical Lattices

该提案呼吁对光学晶格中的原子进行研究，光学晶格中的原子是由特定激光干涉图案中的光移动形成的周期性势能。该提议涉及对Cs原子在光学晶格中的量子运动的实验研究。这一提议将以基态原子为起点，产生和研究原子质心运动的新量子态。它将研究原子在重力存在的情况下通过隧道穿过晶格的传播，这显然类似于电子在存在电场的情况下通过固体的传播。***

The proposal calls for the study of atoms in optical lattices, which are periodic potentials formed by the light shift in specific laser interference patterns. The proposal is concerned with experimental studies of the quantum motion of Cs atoms in optical lattices. This proposal will use ground state atoms as a starting point for the generation and study of new quantum states of atomic center-of-mass motion. It will study the propagation of atoms by tunneling through the lattice in the presence of gravity, in obvious analogy to the propagation of electrons through solids in the presence of an electric field. ***
