Role of Atomic Structure Calculations: From Fundamental Physics to Technological Advancements

Abstract

Atomic structure calculations are critical for advancing fundamental physics and driving technological innovation. They provide essential data for experimental design and interpretation, especially when direct measurements are challenging. These calculations are pivotal in areas such as quantum computing, atomic clocks, quantum sensors, and cold atom physics, as well as in fundamental research, including parity non-conservation, dark matter searches, and gravitational wave detection. This presentation will explore how precise atomic property calculations propel both technological advancements and our understanding of nature. I will discuss: Our research group’s contributions to high-precision atomic property calculations for technological developments in cold atom physics, atomic clocks, and other applications. Recent work addressing challenges in atomic structure theory, including basis sets, spurious states, and modeling properties of Rydberg atoms for quantum computing. The design and underlying concepts of the atomic cyberinfrastructure under development in our group.
