| Title | The Strontium Molecular Lattice Clock : Vibrational Spectroscopy with Hertz-Level Accuracy |
| Author(s) | Leung, Kon H |
| Publication | Cham, 1. Imprint: Springer
2. Springer Nature Switzerland, 2024. |
| Description | XV, 161 p. 57 illus., 53 illus. in color : online resource |
| Abstract Note | This thesis describes how the rich internal degrees of freedom of molecules can be exploited to construct the first ???clock??? based on ultracold molecules, rather than atoms. By holding the molecules in an optical lattice trap, the vibrational clock is engineered to have a high oscillation quality factor, facilitating the full characterization of frequency shifts affecting the clock at the hertz level. The prototypical vibrational molecular clock is shown to have a systematic fractional uncertainty at the 14th decimal place, matching the performance of the earliest optical atomic lattice clocks. As part of this effort, deeply bound strontium dimers are coherently created, and ultracold collisions of these Van der Waals molecules are studied for the first time, revealing inelastic losses at the universal rate. The thesis reports one of the most accurate measurements of a molecule???s vibrational transition frequency to date. The molecular clock lays the groundwork for explorations into terahertz metrology, quantum chemistry, and fundamental interactions at atomic length scales |

| Title | Optically Trapped Microspheres as Sensors of Mass and Sound : Brownian Motion as Both Signal and Noise |
| Author(s) | Hillberry, Logan Edward |
| Publication | Cham, 1. Imprint: Springer
2. Springer Nature Switzerland, 2023. |
| Description | XVI, 115 p. 44 illus., 39 illus. in color : online resource |
| Abstract Note | This thesis makes significant advances in the use of microspheres in optical traps as highly precise sensing platforms. While optically trapped microspheres have recently proven their dominance in aqueous and vacuum environments, achieving state-of-the-art measurements of miniscule forces and torques, their sensitivity to perturbations in air has remained relatively unexplored. This thesis shows that, by uniquely operating in air and measuring its thermally-fluctuating instantaneous velocity, an optically trapped microsphere is an ultra-sensitive probe of both mass and sound. The mass of the microsphere is determined with similar accuracy to competitive methods but in a fraction of the measurement time and all while maintaining thermal equilibrium, unlike alternative methods. As an acoustic transducer, the air-based microsphere is uniquely sensitive to the velocity of sound, as opposed to the pressure measured by a traditional microphone. By comparison to state-of-the-art commercially-available velocity and pressure sensors, including the world???s smallest measurement microphone, the microsphere sensing modality is shown to be both accurate and to have superior sensitivity at high frequencies. Applications for such high-frequency acoustic sensing include dosage monitoring in proton therapy for cancer and event discrimination in bubble chamber searches for dark matter. In addition to reporting these scientific results, the thesis is pedagogically organized to present the relevant history, theory, and technology in a straightforward way |

| Title | An Introduction to Modern Timekeeping and Time Transfer |
| Author(s) | Banerjee, Parameswar;Matsakis, Demetrios |
| Publication | Cham, 1. Imprint: Springer
2. Springer Nature Switzerland, 2023. |
| Description | XVII, 303 p. 229 illus., 194 illus. in color : online resource |
| Abstract Note | This book provides a comprehensive, systematic description of modern timekeeping and its specializations. Introductory chapters discuss the concept of time and its definition, then briefly look at pre-Atomic Era timekeeping to set the stage for the introduction of the atomic clock. Subsequent chapters focus on concepts such as frequency stability and measurement uncertainty, as well as computer network time-synchronization protocols including Network Time Protocol (NTP) and Precise Time Protocol (PTP). The book then delves into the nuts and bolts of the Global Navigation Satellite Systems (GNSS), Two-Way Satellite Time and Frequency Transfer, and Optical Time and Frequency Transfer. Timescale theory is then described as a way to combine clock data, and the algorithms and procedures used to generate Coordinated Universal Time (UTC) are given. Finally, there is a look at modern applications of timekeeping and time transfer. Featuring a glossary of all key terms, this book is highly recommended for trained or incoming physicists, engineers, or mathematicians working, for example, in manufacturing or timing laboratories. Additionally, it is suitable for use in introductory university courses dealing with the subject of timekeeping |

| Title | Engineering Metrology for Pedestrian Falls Prevention and Protection : Theories to Applications for Designing Safer Shoes and Floors |
| Author(s) | Kim, In-Ju |
| Publication | Cham, 1. Imprint: Springer
2. Springer International Publishing, 2022. |
| Description | XLVII, 520 p. 207 illus., 90 illus. in color : online resource |
| Abstract Note | This book explains how to improve the validity, reliability, and repeatability of slip resistance assessments amongst a range of shoes, floors, and environments from an engineering metrology viewpoint???covering theoretical and experimental aspects of slip resistance mechanics and mechanisms. Pedestrian falls resulting from slips or falls are one of the foremost causes of fatal and non-fatal injuries that limit people???s functionality. There have been prolonged efforts globally to identify and understand their main causes and reduce their frequency and severity. This book deals with large volumes of information on tribological characteristics such as friction and wear behaviours of the shoes and floors and their interactive impacts on slip resistance performances. Readers are introduced to theoretical concepts and models and collected evidence on slip resistance properties amongst a range of shoe and floor types and materials under various ambulatory settings. These approaches can be used to develop secure design strategies against fall incidents and provide a great step forward to build safer shoes, floors, and walking/working environments for industries and communities around the world. The book includes many case studies |
