- 요약Clock atom interferometry is an emerging technique that combines the precision of atomic clocks with established measurement techniques in matter-wave interferometry. It offers a new way of helping us to explore fundamental physics and measure practical inertial signals with unprece-dented sensitivity. This versatile tool has promising applications in areas such as gravitational wave detection, dark matter searches, and geodesy. The sensitivity of clock atom interferometers to many signals of interest scales with both the sensor baseline and the momentum transferred to the atoms. This thesis presents work aimed at advancing both aspects through the development of new techniques and technologies for clock atom interferometry.Chapter 1 introduces the field of clock atom interferometry, including relevant atomic physics background and several motivating applications. Chapter 2 describes the experimental setup used to investigate Floquet atom optics, a novel technique presented in Chapter 3. Floquet atom optics enables compensation for differential Doppler shifts in large momentum transfer interferometers by applying a periodic atom-light coupling. This approach allows for efficient atom opties across a wide range of frequency offsets, even in the strong drive regime, where the detuning is comparable to the Rabi frequency. Using this method, we demonstrated atom interferometers with over 400 hk of momentum separation. The underlying formalism and mathematical framework of this technique are detailed in Chapter 4.The second half of this thesis focuses on the construction and commissioning of a 10-meter ultra-high vacuum tower designed for long-baseline interferometry. Chapter 5 outlines the design and components of the tower. Chapter 6 discusses the development and testing of high-voltage electrodes installed in each tower segment, which may allow for a test of the neutrality of matter. Chapter 7 highlights the connection nodes. This critical region of the tower houses in-vacuum optics used to launch atoms into free fall at the start of a sequence and detect them at the end of an interferometer sequence. Finally, Chapter 8 describes our methods for assembling the various tower components and safely installing the tower in our lab space.Both Floquet atom optics and our state-of-the-art vacuum tower lay the foundation for next-generation interferometers capable of probing new frontiers in precision sensing and fundamental physics. I provide a few examples of how these techniques could be used together in the concluding chapter, Chapter 9.
