Book Description
[Truncated abstract] This thesis is comprised of two parts: The first part details the implementation of two room temperature sapphire Fabry-Perot cavities as an optical frequency reference. The second part presents the first optical odd-parity test of Lorentz invariance, using an asymmetric optical resonator. We draw from the developments in the rst part of the thesis to maximize the performance of the odd-parity test of Lorentz invariance. While sapphire presents material properties superior to the ULE and fused silica commonly used in Fabry-Perot resonators, the non-zero coe cient of thermal expansion of sapphire necessitates a high degree of temperature control. The optical cavities are housed in separate vacuum chambers with multi-stage temperature control reaching nanoKelvin stability over a second. To frequency lock the 1064 nm laser to the stable Fabry-Perot cavities we use the Pound-Drever-Hall technique and employ Acousto-Optic Modulators (AOM) for fast frequency control...

Book Description
This thesis describes one of the most precise experimental tests of Lorentz symmetry in electrodynamics by light-speed anisotropy measurement with an asymmetric optical ring cavity. The author aims to answer the fundamental, hypothetical debate on Lorentz symmetry in the Universe. He concludes that the symmetry is protected within an error of 10-15, which means providing one of the most stringent upper limits on the violation of the Lorentz symmetry in the framework of the Standard Model Extension. It introduces the following three keys which play an important role in achieving high-precision measurement: (1) a high-index element (silicon) interpolated into part of the light paths in the optical ring cavity, which improves sensitivity to the violation of the Lorentz symmetry, (2) double-pass configuration of the interferometer, which suppresses environmental noises, and (3) continuous data acquisition by rotating the optical ring cavity, which makes it possible to search for higher-order violations of Lorentz symmetry. In addition to those well-described keys, a comprehensive summary from theoretical formulations to experimental design details, data acquisition, and data analysis helps the reader follow up the experiments precisely.

Book Description
Thermal noise from optical coatings is a growing area of concern and overcoming limits to the sensitivity of high precision measurements by thermal noise is one of the greatest challenges faced by experimental physicists. In this timely book, internationally renowned scientists and engineers examine our current theoretical and experimental understanding. Beginning with the theory of thermal noise in mirrors and substrates, subsequent chapters discuss the technology of depositing coatings and state-of-the-art dielectric coating techniques used in precision measurement. Applications and remedies for noise reduction are also covered. Individual chapters are dedicated to specific fields where coating thermal noise is a particular concern, including the areas of quantum optics/optomechanics, gravitational wave detection, precision timing, high-precision laser stabilisation via optical cavities and cavity quantum electrodynamics. While providing full mathematical detail, the text avoids field-specific jargon, making it a valuable resource for readers with varied backgrounds in modern optics.

Book Description
Lorentz and CPT invariance is a feature of the Standard Model of particle physics and of theories of gravity such as Einstein's general relativity. However, an underlying theory such as strings may introduce small violations of Lorentz and CPT symmetry. This book consists of reviews from about 50 experts in the field, covering theoretical and experimental studies of these relativity-violating effects. It comprises the Proceedings of the Third Meeting on CPT and Lorentz Symmetry, held at Indiana University in Bloomington.The Meeting focused on recent developments involving fundamental spacetime symmetries and included theoretical scenarios and experimental searches for possible relativity violations. Experimental subjects covered include resonant-cavity and interferometric behavior of photons, oscillations of neutrinos and neutral mesons, clock-comparison measurements on the Earth and in space, astrophysical observations, tests with macroscopic matter, spectroscopy of hydrogen and antihydrogen, studies of particle properties and behavior, and gravitational tests. Theoretical topics covered include physical effects at the level of the Standard Model and beyond, the possible origins and mechanisms for Lorentz and CPT violations, and associated issues in particle physics, field theory, gravity, and string theory.

Book Description
The Marcel Grossmann Meetings are three-yearly forums that meet to discuss recent advances in gravitation, general relativity and relativistic field theories, emphasizing their mathematical foundations, physical predictions and experimental tests. These meetings aim to facilitate the exchange of ideas among scientists, to deepen our understanding of space-time structures, and to review the status of ongoing experiments and observations testing Einstein's theory of gravitation either from ground or space-based experiments. Since the first meeting in 1975 in Trieste, Italy, which was established by Remo Ruffini and Abdus Salam, the range of topics presented at these meetings has gradually widened to accommodate issues of major scientific interest, and attendance has grown to attract more than 900 participants from over 80 countries.This proceedings volume of the eleventh meeting in the series, held in Berlin in 2006, highlights and records the developments and applications of Einstein's theory in diverse areas ranging from fundamental field theories to particle physics, astrophysics and cosmology, made possible by unprecedented technological developments in experimental and observational techniques from space, ground and underground observatories. It provides a broad sampling of the current work in the field, especially relativistic astrophysics, including many reviews by leading figures in the research community.
