This book collects lecture courses and seminars given at the Les Houches Summer School 2010 on "Quantum Theory: From Small to Large Scales". Fundamental quantum phenomena appear on all scales, from microscopic to macroscopic. Some of the pertinent questions include the onset of decoherence, the dynamics of collective modes, the influence of external randomness and the emergence of dissipative behaviour. Our understanding of such phenomena has been advanced by the study of model systems and by the derivation and analysis of effective dynamics for large systems and over long times. In this field, research in mathematical physics has regularly contributed results that were recognized as essential in the physics community. During the last few years, the key questions have been sharpened and progress on answering them has been particularly strong. This book reviews the state-of-the-art developments in this field and provides the necessary background for future studies. All chapters are written from a pedagogical perspective, making the book accessible to master and PhD students and researchers willing to enter this field.

We may have lived knowing that the world around us operates in a way as if we observe them to be. This knowledge of how the universe operates, based primarily of our observations, has enabled us to predict actions and motions and allowed us to build machines and equipments that have made our lives easier and more enjoyable. The field that allowed us to do that is classical physics. The world, however, is advancing and our knowledge of how things are expands over time. We have discovered in the last few decades that these sets of rules that we have devised can perfectly describe the large-scale world but cannot accurately define the behaviors of particles in the microscopic world. This necessitated another field to explain the different behavior in the microscopic world: quantum physics.

Currently, the General Theory of Relativity (GTR) describes the physics of the very large in terms of classical physics, while quantum theory describes the physics of the very small in terms of the Standard Model of particle physics. Unfortunately, the two theories are incompatible and do not describe satisfactorily all the forces between the various particles comprising ordinary matter. At present, one of the deepest problems in theoretical physics is harmonizing the GTR, which describes gravitation, with quantum mechanics, which describes the other three fundamental forces acting on the atomic scale. The main aim of the book is to provide an understanding of gravity in terms of a quantum theory given by the Generation Model of particle physics. The book presents a fully quantum theory of gravity, which describes both the large cosmological scale and the small atomic scale interactions between all particles.

Absolutely Small presents (and demystifies) the world of quantum science like no book before. Physics is a complex, daunting topic, but it is also deeply satisfying?even thrilling. When liberated from its mathematical underpinnings, physics suddenly becomes accessible to anyone with the curiosity and imagination to explore its beauty. Science without math? It’s not that unusual. For example, we can understand the concept of gravity without solving a single equation. So for all those who may have pondered what makes blueberries blue and strawberries red; for those who have wondered if sound really travels in waves; and why light behaves so differently from any other phenomenon in the universe, it’s all a matter of quantum physics. This book explores in considerable depth scientific concepts using examples from everyday life, such as: particles of light, probability, states of matter, what makes greenhouse gases bad Challenging without being intimidating, accessible but not condescending, Absolutely Small develops your intuition for the very nature of things at their most basic and intriguing levels.

Today we are blessed with two extraordinarily successful theories of physics. The first is Albert Einstein's general theory of relativity, which describes the large-scale behaviour of matter in a curved spacetime. This theory is the basis for the standard model of big bang cosmology. The discovery of gravitational waves at the LIGO observatory in the US (and then Virgo, in Italy) is only the most recent of this theory's many triumphs. The second is quantum mechanics. This theory describes the properties and behaviour of matter and radiation at their smallest scales. It is the basis for the standard model of particle physics, which builds up all the visible constituents of the universe out of collections of quarks, electrons and force-carrying particles such as photons. The discovery of the Higgs boson at CERN in Geneva is only the most recent of this theory's many triumphs. But, while they are both highly successful, these two structures leave a lot of important questions unanswered. They are also based on two different interpretations of space and time, and are therefore fundamentally incompatible. We have two descriptions but, as far as we know, we've only ever had one universe. What we need is a quantum theory of gravity. Approaches to formulating such a theory have primarily followed two paths. One leads to String Theory, which has for long been fashionable, and about which much has been written. But String Theory has become mired in problems. In this book, Jim Baggott describes

Quantum mechanics is a theory in physics that explains the physical properties of nature at the atomic and subatomic levels. It is fundamental to the study of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science. Classical physics defines many aspects of nature at an ordinary scale, while quantum mechanics describes the aspects of nature at small scales. Most theories in classical physics can be derived from quantum mechanics as an estimation valid at large scale. Quantum mechanics is used to describe observations which could not be resolved with classical physics. This book attempts to understand the multiple branches that fall under this discipline and how such concepts have practical applications. Different approaches, evaluations, methodologies and advanced studies on quantum mechanics have been included herein. The extensive content of this book provides the readers with a thorough understanding of the subject.

over this stochastic space-time leads to the non local fields considered by G. V. Efimov. In other words, stochasticity of space-time (after being averaged on a large scale) as a self-memory makes the theory nonlocal. This allows one to consider in a unified way the effect of stochasticity (or nonlocality) in all physical processes. Moreover, the universal character of this hypothesis of space-time at small distances enables us to re-interpret the dynamics of stochastic particles and to study some important problems of the theory of stochastic processes [such as the relativistic description of diffusion, Feynman type processes, and the problem of the origin of self-turbulence in the motion of free particles within nonlinear (stochastic) mechanics]. In this direction our approach (Part II) may be useful in recent developments of the stochastic interpretation of quantum mechanics and fields due to E. Nelson, D. Kershaw, I. Fenyes, F. Guerra, de la Pena-Auerbach, J. -P. Vigier, M. Davidson, and others. In particular, as shown by N. Cufaro Petroni and J. -P. Vigier, within the discussed approach, a causal action-at-distance interpretation of a series of experiments by A. Aspect and his co-workers indicating a possible non locality property of quantum mechanics, may also be obtained. Aspect's results have recently inspired a great interest in different nonlocal theories and models devoted to an understanding of the implications of this nonlocality. This book consists of two parts.

As part of the Physics 2010 decadal survey project, the Department of Energy and the National Science Foundation requested that the National Research Council assess the opportunities, over roughly the next decade, in atomic, molecular, and optical (AMO) science and technology. In particular, the National Research Council was asked to cover the state of AMO science, emphasizing recent accomplishments and identifying new and compelling scientific questions. Controlling the Quantum World, discusses both the roles and challenges for AMO science in instrumentation; scientific research near absolute zero; development of extremely intense x-ray and laser sources; exploration and control of molecular processes; photonics at the nanoscale level; and development of quantum information technology. This book also offers an assessment of and recommendations about critical issues concerning maintaining U.S. leadership in AMO science and technology.

Massively Small takes you on a fascinating journey through cutting-edge science-from particle physics to astrophysics-unifying today's incompatible theories with a surprisingly simple idea from the dawn of science itself. For as long as human beings have had self-consciousness, we have wondered about the origins of the universe. Today, we use science to make sense of the world around us. Yet, despite the paradigm-shifting work of such pioneers as Isaac Newton, Max Plank, and Albert Einstein, among many others, modern theories such as photons, gravitons, motion, matter, space, and time all have major inconsistencies. Written for the general public, Massively Small identifies and articulates the anomalies plaguing the current physics. And by presenting new ideas in a novel framework-a framework drawn from ancient conceptualizations of the fundamental structure of reality-it boldly begins the process of shifting the paradigm yet again. From quantum mechanics to relativity, from theories of time, light, gravity, and mass to the cosmological theory of the big bang, this book shows how every question in physics can be answered by viewing the microstructures of the universe in a particular way. The ultimate goal is to reach a large-scale unified theory by beginning at the smallest scale.
