Title: Novel computational perspectives on matter-wave interferometry

Abstract: Matter-wave interferometry holds promise as a powerful quantum sensing technique for fundamental physics. From a theoretical standpoint, it is essential to identify the observables that can be accessed experimentally and compute signatures from phenomena of interest in a tractable and consistent manner. In this talk, I will present two novel approaches that achieve this: one for computing general relativistic effects in atom gradiometers, and another for calculating coherently enhanced collisional signatures in multi-particle interferometers. I will show how these formalisms provide a streamlined and transparent method for studying the signatures of gravitational waves and dark matter in matter-wave interferometers. Additionally, I will explain how these frameworks shed light on the similarities and differences between matter-wave interferometers and other detectors, such as laser interferometers and dark matter direct detection experiments.
