数字信号在原子芯片中的应用

An application of digital signals in an atom Chip

通过分析和计算不同谐波分量与原子相互作用产生不同的势场,发现可以将其叠加在一起形成原子囚禁势,提出了数字信号在原子芯片中的应用方案.

Digital signals （square wave） are superpositions of many frequency components in frequency domain. We analyze and calculate the coupling potentials between the atom and the frequency components respectively,and demonstrate that the atomic trapping adiabatic potential can be generated by taking into account the total coupling potential. An application scheme of the digital signal in an atom chip is proposed.
