From Varying Couplings to Fundamental Physics

8:06 AM Nrf

Description

Nature is characterized by a number of physical laws and fundamental dimensionless couplings. These determine the properties of our physical universe, from the size of atoms, cells and mountains to the ultimate fate of the universe as a whole. Yet it is rather remarkable how little we know about them. The constancy of physical laws is one of the cornerstones of the scientific research method, but for fundamental couplings this is an assumption with no other justification than a historical assumption. There is no 'theory of constants' describing their role in the underlying theories and how they relate to one another or how many of them are truly fundamental. Studying the behaviour of these quantities throughout the history of the universe is an effective way to probe fundamental physics. This explains why the ESA and ESO include varying fundamental constants among their key science drivers for the next generation of facilities. This symposium discussed the state-of-the-art in the field, as well as the key developments anticipated for the coming years.

Principles Laser Spectroscopy & Quantum Optics

4:32 AM Nrf

Book Description

Princeton University Press, Jan 12, 2011 - Science - 520 pages

Principles of Laser Spectroscopy and Quantum Optics is an essential textbook for graduate students studying the interaction of optical fields with atoms. It also serves as an ideal reference text for researchers working in the fields of laser spectroscopy and quantum optics.
The book provides a rigorous introduction to the prototypical problems of radiation fields interacting with two- and three-level atomic systems. It examines the interaction of radiation with both atomic vapors and condensed matter systems, the density matrix and the Bloch vector, and applications involving linear absorption and saturation spectroscopy. Other topics include hole burning, dark states, slow light, and coherent transient spectroscopy, as well as atom optics and atom interferometry. In the second half of the text, the authors consider applications in which the radiation field is quantized. Topics include spontaneous decay, optical pumping, sub-Doppler laser cooling, the Heisenberg equations of motion for atomic and field operators, and light scattering by atoms in both weak and strong external fields. The concluding chapter offers methods for creating entangled and spin-squeezed states of matter.
Instructors can create a one-semester course based on this book by combining the introductory chapters with a selection of the more advanced material. A solutions manual is available to teachers.

Fundamental & Application in Aerosol Spectroscopy

4:07 AM Nrf

Book Description

Taylor & Francis Group, Jun 15, 2010 - Science - 509 pages

"Helping you better understand the processes, instruments, and methods of aerosol spectroscopy, fundamentals and applications in aerosol spectroscopy provides an overview of the state of the art in this rapidly developing field. It covers fundamental aspects of aerosol spectroscopy, applications to atmospherically and astronomically relevant problems, and several aspects that need further research and development.Chapters in the book are arranged in order of decreasing wavelength of the light/electrons. The text starts with infrared spectroscopy, one of the most important aerosol characterization methods for laboratory studies, field measurements, remote sensing, and space missions. It then focuses on Raman spectroscopy for investigating aerosol processes in controlled laboratory studies and for analyzing environmental particles and atmospheric pollution. The next section discusses the use of cavity ring-down spectroscopy to measure light extinction, laser-induced fluorescence spectroscopy to identify and classify biological aerosol particles, and ultrafast laser techniques to improve the specificity of bioaerosol detection. The final section examines recent developments involving novel techniques based on UV, X-ray, and electron beam studies.This book offers the first comprehensive overview of the spectroscopy of aerosols. It includes some results for the first time in the literature and presents a unique link between fundamental aspects and applications"

Atomic and Molecular Spectroscopy

3:56 AM Nrf

Book Description

Springer, 2004 - Science - 588 pages

Atomic and Molecular Spectroscopy is a wide-ranging review of modern spectroscopic techniques such as X-ray, photoelectron, optical and laser spectroscopy, and radiofrequency and microwave techniques. On the fundamental side it focuses on physical principles and the impact of spectroscopy on our understanding of the building blocks of matter, while in the area of applications particular attention is given to those in chemical analysis, photochemistry, surface characterisation, environmental and medical diagnostics, remote sensing and astrophyscis. The Fourth Edition also provides the reader with an update on laser cooling and trapping, Bose-Einstein condensation, ultra-fast spectroscopy, high-power laser/matter interaction, satellite-based astronomy and spectroscopic aspects of laser medicine. Important references are also brought up to date.
