Systems and methods for a cold atom frequency standard

摘要

Systems and methods for a cold atom frequency standard are provided herein. In certain embodiments, a cold atom microwave frequency standard includes a vacuum cell, the vacuum cell comprising a central cylinder, the central cylinder being hollow and having a first open end and a second open end; a first end portion joined to the first open end; and a second end portion joined to the second open end, wherein the first end portion, the central cylinder, and the second end portion enclose a hollow volume containing atoms, the first end portion and the second end portion configured to allow light to enter into the hollow volume. The cold atom microwave frequency standard also includes a cylindrically symmetric resonator encircling the central cylinder, wherein the resonator generates a microwave field in the hollow volume at the resonant frequency of the atoms.
