This book brings together two broad themes that have generated a great deal of interested and excitement in the scientific and technical community in the last 100 years or so: quantum tunnelling and nonlinear dynamical systems. It applies these themes to nanostructured solid state heterostructures operating at room temperature to gain insight into novel photonic devices, systems and applications.

For a physicist noise is not just about sounds. It refers to any random physical process that blurs measurements and, in so doing, stands in the way of scientific knowledge. This short book deals with the most common types of noise, their properties, and some of their unexpected virtues. The text assumes that the reader knows the basics of probability theory and explains the most useful mathematical concepts related to noise. Finally, it aims at making this subject more widely known, and stimulating interest in its study in young physicists.

The first part of this text provides an overview of the physics of lasers and it describes some of the more common types of lasers and their applications. The production of laser light requires the formation of a resonant cavity where stimulated emission of radiation occurs. The light produced in this way is intense, coherent and monochromatic. Applications of lasers include CD/DVD players, laser printers and fiber optic communication devices. While these devices depend largely on the monochromaticity and coherence of the light that lasers produce, other well-known applications, such as laser machining and laser fusion depend on the intensity of laser light. The second part of the book describes the phenomenon of Bose-Einstein condensation. These condensates represent a state of matter that exists in some dilute gases at very low temperature as predicted first by Satyendra Nath Bose and Albert Einstein. Bose-Einstein condensates were first observed experimentally in 1995 by Eric Cornell and Carl Wieman at the University of Colorado, and shortly thereafter by Wolfgang Ketterle at the Massachusetts Institute of Technology. The experimental techniques used to create a Bose-Einstein condensate provide an interesting and unconventional application of lasers: the cooling and confinement of a dilute gas at very low temperature.

Semiconductors and Modern Electronics is a brief introduction to the physics behind semiconductor technologies. Chuck Winrich explores the topic of semiconductors from a qualitative approach to understanding the theories and models used to explain semiconductor devices, which is intended to bring the advanced ideas behind semiconductors to a broader audience of students who will not major in physics. Applications of semiconductors are explored and understood through the models developed in the book. Much of the inspiration for this text comes from Winrich's experience teaching a general electronics course to students majoring in business. The goal of that class, and this work, is to bring forward the science behind semiconductors, and then to look at how that science affects the lives of people.

Electrostatic accelerators have been at the forefront of modern technology since 1932, when Sir John Cockroft and Ernest Walton developed the first accelerator. Although the electrostatic accelerator field is more than 90 years old, the field and the number of accelerators is growing more rapidly than ever. This book provides an overview of the basic science and technology that underlies the electrostatic accelerator field so it can serve as a reference guide and textbook for accelerator engineers as well as students and researchers who work with electrostatic accelerators.

This hands-on guide is primarily intended to be used in undergraduate laboratories in the physical sciences and engineering. It assumes no prior knowledge of statistics. It introduces the necessary concepts where needed, with key points illustrated with worked examples and graphic illustrations. In contrast to traditional mathematical treatments it uses a combination of spreadsheet and calculus-based approaches, suitable as a quick and easy on-the-spot reference. The emphasis throughout is on practical strategies to be adopted in the laboratory.
Error analysis is introduced at a level accessible to school leavers, and carried through to research level. Error calculation and propagation is presented though a series of rules-of-thumb, look-up tables and approaches amenable to computer analysis. The general approach uses the chi-square statistic extensively. Particular attention is given to hypothesis testing and extraction of parameters and their uncertainties by fitting mathematical models to experimental data. Routines implemented by most contemporary data analysis packages are analysed and explained. The book finishes with a discussion of advanced fitting strategies and an introduction to Bayesian analysis.

Qiu Guangming, the author of this book, has been a researcher on the measuring and weighing systems in China for more thirty years. He has been collecting historical data and examining actual objects, which has resulted in numerous research papers and books. This book examines the systems she has researched.

The first part of this book overviews the physics of lasers and describes some of the more common types of lasers and their applications. Applications of lasers include CD/DVD players, laser printers and fiber optic communication devices. Part II of this book describes the phenomenon of Bose-Einstein condensation. The experimental techniques used to create a Bose-Einstein condensate provide an interesting and unconventional application of lasers; that is, the cooling and confinement of a dilute gas at very low temperature.

This book is an introduction to the mechanical properties, the force generating capacity, and the sensitivity to mechanical cues of the biological system. To understand how these qualities govern many essential biological processes, we also discuss how to measure them. However, before delving into the details and the techniques, we will first learn the operational definitions in mechanics, such as force, stress, elasticity, viscosity and so on. This book will explore the mechanics at three different length scales - molecular, cellular, and tissue levels - sequentially, and discuss the measurement techniques to quantify the intrinsic mechanical properties, force generating capacity, mechanoresponsive processes in the biological systems, and rupture forces.

Semiconductors and Modern Electronics is a brief introduction to the physics behind semiconductor technologies. Chuck Winrich, a physics professor at Babson College, explores the topic of semiconductors from a qualitative approach to understanding the theories and models used to explain semiconductor devices. Applications of semiconductors are explored and understood through the models developed in the book. The qualitative approach in this book is intended to bring the advanced ideas behind semiconductors to the broader audience of students who will not major in physics.

The book covers in particular state-of-the-art scientific research about product quality control and related health and environmental safety topics, including human, animal and plant safety assurance issues. These conference proceedings provide contemporary information on the general theoretical, metrological and practical issues of the production and application of reference materials. Reference materials play an integral role in physical, chemical and related type of measurements, ensuring their uniformity, comparability and the validity of quantitative analysis as well as, as a result, the objectivity of decisions concerning the elimination of technical barriers in commercial and economic, scientific and technical and other spheres of cooperation. The book is intended for researchers and practitioners in the field of chemistry, metrologists, technical physics, as well as for specialists in analytical laboratories, or working for companies and organizations involved in the production, distribution and use of reference materials.

Photoemission (also known as photoelectron) spectroscopy refers to the process in which an electron is removed from a specimen after the atomic absorption of a photon. The first evidence of this phenomenon dates back to 1887 but it was not until 1905 that Einstein offered an explanation of this effect, which is now referred to as ""the photoelectric effect"". Quantitative Core Level Photoelectron Spectroscopy: A Primer tackles the pragmatic aspects of the photoemission process with the aim of introducing the reader to the concepts and instrumentation that emerge from an experimental approach. The basic elements implemented for the technique are discussed and the geometry of the instrumentation is explained. The book covers each of the features that have been observed in the X-ray photoemission spectra and provides the tools necessary for their understanding and correct identification. Charging effects are covered in the penultimate chapter with the final chapter bringing closure to the basic uses of the X-ray photoemission process, as well as guiding the reader through some of the most popular applications used in current research.

Electrostatic Accelerators have been at the forefront of modern technology since the development by Sir John Cockroft and Ernest Walton in 1932 of the first accelerator, which was the first to achieve nuclear transmutation and earned them the Nobel Prize in Physics in 1951. The applications of Cockroft and Walton's development have been far reaching, even into our kitchens where it is employed to generate the high voltage needed for the magnetron in microwave ovens. Other electrostatic accelerator related Nobel prize winning developments that have had a major socio-economic impact are; the electron microscope where the beams of electrons are produced by an electrostatic accelerator, X-rays and computer tomography (CT) scanners where the X-rays are produced using an electron accelerator and microelectronic technology where ion implantation is used to dope the semiconductor chips which form the basis of our computers, mobile phones and entertainment systems. Although the Electrostatic Accelerator field is over 90 years old, and only a handful of accelerators are used for their original purpose in nuclear physics, the field and the number of accelerators is growing more rapidly than ever. The objective of this book is to collect together the basic science and technology that underlies the Electrostatic Accelerator field so it can serve as a handbook, reference guide and textbook for accelerator engineers as well as students and researchers who work with Electrostatic Accelerators.

Combinatorial Kalman filters are a standard tool today for pattern recognition and charged particle reconstruction in high energy physics. In this thesis the implementation of the track finding software for the Belle II experiment and first studies on early Belle II data are presented. The track finding algorithm exploits novel concepts such as multivariate track quality estimates to form charged trajectory hypotheses combining information from the Belle II central drift chamber with the inner vertex sub-detectors. The eventual track candidates show an improvement in resolution on the parameters describing their spatial and momentum properties by up to a factor of seven over the former legacy implementation. The second part of the thesis documents a novel way to determine the collision event null time T0 and the implementation of optimisation steps in the online reconstruction code, which proved crucial in overcoming the high level trigger limitations.

Atomic Physics provides a concise treatment of atomic physics and a basis to prepare for work in other disciplines that are underpinned by atomic physics, such as chemistry, biology and several aspects of engineering science. The focus is mainly on atomic structure since this is what is primarily responsible for the physical properties of atoms. After a brief introduction to some basic concepts, the perturbation theory approach follows the hierarchy of interactions starting with the largest. The other interactions of spin, and angular momentum of the outermost electrons with each other, the nucleus and external magnetic fields are treated in order of descending strength. A spectroscopic perspective is generally taken by relating the observations of atomic radiation emitted or absorbed to the internal energy levels involved. X-ray spectra are then discussed in relation to the energy levels of the innermost electrons. Finally, a brief description is given of some modern, laser-based, spectroscopic methods for the high-resolution study of the details of atomic structure.
