A host of astrophysical measurements suggest that most of the matter in the Universe is an invisible, nonluminous substance that physicists call "dark matter." Understanding the nature of dark matter is one of the greatest challenges of modern physics and is of paramount importance to our theories of cosmology and particle physics. This text explores one of the leading hypotheses to explain dark matter: that it consists of ultralight bosons forming an oscillating field that feebly interacts with light and matter.

A host of astrophysical measurements suggest that most of the matter in the Universe is an invisible, nonluminous substance that physicists call “dark matter.” Understanding the nature of dark matter is one of the greatest challenges of modern physics and is of paramount importance to our theories of cosmology and particle physics. This text explores one of the leading hypotheses to explain dark matter: that it consists of ultralight bosons forming an oscillating field that feebly interacts with light and matter. Many new experiments have emerged over the last decade to test this hypothesis, involving state-of-the-art microwave cavities, precision nuclear magnetic resonance (NMR) measurements, dark matter “radios,” and synchronized global networks of atomic clocks, magnetometers, and interferometers. The editors have gathered leading experts from around the world to present the theories motivating these searches, evidence about dark matter from astrophysics, and the diverse experimental techniques employed in searches for ultralight bosonic dark matter. The text provides a comprehensive and accessible introduction to this blossoming field of research for advanced undergraduates, beginning graduate students, or anyone new to the field, with tutorials and solved problems in every chapter. The multifaceted nature of the research – combining ideas and methods from atomic, molecular, and optical physics, nuclear physics, condensed matter physics, electrical engineering, particle physics, astrophysics, and cosmology – makes this introductory approach attractive for beginning researchers as well as members of the broader scientific community. This is an open access book.

A complete treatment of all aspects of dark matter physics This book provides an incisive, self-contained introduction to one of the most intriguing subjects in modern physics, presenting the evidence we have from astrophysics for the existence of dark matter, the theories for what it could be, and the cutting-edge experimental and observational methods for testing them. It begins with a survey of the astrophysical phenomena, from rotation curves to lensing and cosmological structure formation. It goes on to offer the most comprehensive overview available of all three major theories, discussing weakly interacting massive particles (WIMPs), axions, and primordial black holes. The book explains the constraints on each theory, such as direct detection and indirect astrophysical limits, and enables students to build physical intuition using hands-on exercises and supplemental material. The only book to treat extensively WIMPs, axions, and primordial black holes Provides balanced coverage of the evidence, theory, and testing for dark matter from astrophysics, particle physics, and experimental physics Includes original problems and short quizzes throughout Accompanied by Jupyter notebooks that give sample calculations and methods to reproduce key results and graphs An ideal textbook for advanced undergraduate and graduate students and an essential reference for researchers

This book provides a remarkable and complete survey of important questions at the interface between theoretical particle physics and cosmology. After discussing the theoretical and experimental physics revolution that led to the rise of the Standard Model in the past century, the author reviews all the major open puzzles, among them the hierarchy problem, the small value of the cosmological constant, the matter-antimatter asymmetry, and the dark matter enigma, including the state-of-the-art regarding proposed solutions. Also addressed are the rapidly expanding fields of thermal dark matter, cosmological first-order phase transitions and gravitational-wave signatures. In addition, the book presents the original and interdisciplinary PhD research work of the author relating to Weakly-Interacting-Massive-Particles around the TeV scale, which are among the most studied dark matter candidates. Motivated by the absence of experimental evidence for such particles, this thesis explores the possibility that dark matter is much heavier than what is conventionally assumed.

Comprehensive coverage of the principles, technology and diverse applications of optical magnetometry for graduate students and researchers in atomic physics.

In the vast expanse of the cosmos, there exists an enigmatic substance that eludes detection yet exerts a profound influence on the universe's structure and evolution. This substance, known as dark matter, remains one of the greatest mysteries of modern astrophysics, captivating the imaginations of scientists and enthusiasts alike. Dark matter's existence is inferred from its gravitational effects on visible matter and light, yet its nature remains elusive. Despite decades of research and numerous experimental endeavors, the true identity of dark matter continues to evade detection, challenging our understanding of the fundamental constituents of the universe. In parallel, another frontier of scientific exploration has emerged within the intricate ecosystems of the human body: the microbiome. Comprising trillions of microorganisms inhabiting every surface of our bodies, the microbiome plays a crucial role in human health and disease. Yet, like dark matter, much of the microbiome's complexity remains shrouded in mystery, awaiting further exploration and understanding.

This book consists of 3 titles, which are the following: Dark Matter - In the vast expanse of the cosmos, there exists an enigmatic substance that eludes detection yet exerts a profound influence on the universe's structure and evolution. This substance, known as dark matter, remains one of the greatest mysteries of modern astrophysics, captivating the imaginations of scientists and enthusiasts alike. Galaxies - Galaxies are dynamic entities, constantly evolving through processes like mergers, collisions, and interactions with neighboring galaxies. When galaxies merge, their stars, gas, and dust can undergo dramatic transformations, leading to the formation of new stars and restructuring of the galaxy's shape. These interactions can trigger intense bursts of star formation and feed supermassive black holes at the galaxies' centers, leading to the emission of powerful jets of radiation. Quantum Gravity - General relativity, developed by Albert Einstein, describes gravity as the curvature of spacetime caused by mass and energy. It works extremely well at large scales, such as in predicting planetary orbits and the behavior of black holes. On the other hand, quantum mechanics deals with the fundamental behavior of particles at the smallest scales, such as atoms and subatomic particles. It incorporates principles like wave-particle duality, quantization, and uncertainty.
