Quantum Boundaries of Life, Volume 82 in the Advances in Quantum
Chemistry series, presents current topics in this rapidly
developing field that have emerged at the cross section of
mathematics, physics, chemistry and biology. Topics covered include
Quantum Considerations of Neural Memory, Functional Neural Electron
Transport, Plasmon-polariton mechanism of the saltatory conduction
in myelinated axons, Quantum Field Theory Formulation of Brain
Dynamics: Nonequilibrium, Multi Field Theory Formulation of Brain
Dynamics, Quantum Protein Folding, Classical-Quantum Interplay in
Living Neural Tissue Function, Quantum Effects in Life Dynamics,
Quantum transport and utilization of free energy in protein
a-helices, and much more. The book's message is simple. Mystics
prefer to put consciousness in the cosmos to avoid Darwinism. If
the seat of consciousness is found to evolve within all animals,
then we have a Darwinian understanding not only of the origin of
life and species according to natural selection but also concerning
consciousness and, in particular, life being quantum Darwinian.
Gas phase molecular spectroscopy is a powerful tool for obtaining
information on the geometry and internal structure of isolated
molecules and their interactions with others. It enables the
understanding and description, through measurements and modeling,
of the influence of pressure on light absorption, emission, and
scattering by gas molecules, which must be taken into account for
the correct analysis and prediction of the resulting spectra.
Collisional Effects on Molecular Spectra: Laboratory Experiments
and Models, Consequences for Applications, Second Edition provides
an updated review of current experimental techniques, theoretical
knowledge, and practical applications. After an introduction to
collisional effects on molecular spectra, the book moves on by
taking a threefold approach: it highlights key models, reviews
available data, and discusses the consequences for applications.
These include areas such as heat transfer, remote sensing, optical
sounding, metrology, probing of gas media, and climate predictions.
This second edition also contains, with respect to the first one,
significant amounts of new information, including 23 figures, 8
tables, and around 700 references. Drawing on the extensive
experience of its expert authors, Collisional Effects on Molecular
Spectra: Laboratory Experiments and Models, Consequences for
Applications, Second Edition, is a valuable guide for all those
involved with sourcing, researching, interpreting, or applying gas
phase molecular spectroscopy techniques across a range of fields.

It was not until 1971 that the authority for defining scientific
units, the General Conference of Weights and Measures got around to
defining the unit that is the basis of chemistry (the mole, or the
quantity of something). Yet for all this tardiness in putting the
chemical sciences on a sound quantitative basis, chemistry is an
old and venerable subject and one naturally asks the question, why?
Well, the truth is that up until the mid-1920s, many physicists did
not believe in the reality of molecules. Indeed, it was not until
after the physics community had accepted Ernest Rutherford's 1913
solar-system-like model of the atom, and the quantum mechanical
model of the coupling of electron spins in atoms that physicists
started to take seriously the necessity of explaining the chemical
changes that chemists had been observing, investigating and
recording since the days of the alchemists.
Practically every display technology in use today relies on the
flat, energy-efficient construction made possible by liquid
crystals. These displays provide visually-crisp, vibrantly-colored
images that a short time ago were thought only possible in science
fiction. Liquid crystals are known mainly for their use in display
technologies, but they also provide many diverse and useful
applications: adaptive optics, electro-optical devices, films,
lasers, photovoltaics, privacy windows, skin cleansers and soaps,
and thermometers. The striking images of liquid crystals changing
color under polarized lighting conditions are even on display in
many museums and art galleries - true examples of 'science meeting
art'. Although liquid crystals provide us with visually stunning
displays, fascinating applications, and are a rich and fruitful
source of interdisciplinary research, their full potential may yet
remain untapped.
This book provides a brief exposition of the principles of beam
physics and particle accelerators with an emphasis on numerical
examples employing readily available computer tools. However, it
avoids detailed derivations, instead inviting the reader to use
general high-end languages such as Mathcad and Matlab, as well as
specialized particle accelerator codes (e.g. MAD, WinAgile,
Elegant, and others) to explore the principles presented. This
approach allows readers to readily identify relevant design
parameters and their scaling. In addition, the computer input files
can serve as templates that can be easily adapted to other related
situations. The examples and computer exercises comprise basic
lenses and deflectors, fringe fields, lattice and beam functions,
synchrotron radiation, beam envelope matching, betatron resonances,
and transverse and longitudinal emittance and space charge. The
last chapter presents examples of two major types of particle
accelerators: radio frequency linear accelerators (RF linacs) and
storage rings. Lastly, the appendix gives readers a brief
description of the computer tools employed and concise instructions
for their installation and use in the most popular computer
platforms (Windows, Macintosh and Ubuntu Linux). Hyperlinks to
websites containing all relevant files are also included. An
essential component of the book is its website (actually part of
the author's website at the University of Maryland), which contains
the files that reproduce results given in the text as well as
additional material such as technical notes and movies.
The effect which now bears his name, was discovered in 1958 by
Rudolf Moessbauer at the Technical University of Munich. At first,
this appeared to be a phenomenon related to nuclear energy levels
that provided some information about excited state lifetimes and
quantum properties. However, it soon became apparent that
Moessbauer spectroscopy had applications in such diverse fields as
general relativity, solid state physics, chemistry, materials
science, biology, medical physics, archeology and art. It is the
extreme sensitivity of the effect to the atomic environment around
the probe atom as well as the ability to apply the technique to
some interesting and important elements, most notably iron, that is
responsible for the Moessbauer effect's extensive use. The present
volume reviews the historical development of the Moessbauer effect,
the experimental details, the basic physics of hyperfine
interactions and some of the numerous applications of Moessbauer
effect spectroscopy.
While neutron halos were discovered 30 years ago, this is the first
book written on the subject of this exotic form of nuclei that
typically contain many more neutrons than stable isotopes of those
elements. It provides an introductory description of the halo and
outlines the discovery and evidence for its existence. It also
discusses different theoretical models of the halo's structure as
well as models and techniques in reaction theory that have allowed
us to study the halo. This is written at a level accessible to
graduate students starting a PhD in nuclear physics. Halo nuclei
are an exotic form of atomic nuclei that contain typically many
more neutrons than stable isotopes of those elements. To give you a
famous example, an atom of the element lithium has three electrons
orbiting a nucleus with three protons and, usually, either 3 or 4
neutrons. The difference in the number of neutrons gives us two
different isotopes of lithium, Li6 and Li7. But if you keep adding
neutrons to the nucleus you will eventually reach Li11, with still
3 protons (that means it's lithium) but with 8 neutrons. This
nucleus is so neutron-rich that the last two are very weakly bound
to the rest of the nucleus (a Li9 core). What happens is a quantum
mechanical effect: the two outer neutrons float around beyond the
rest of the nuclear core at a distance that is beyond the range of
the force that is holding them to the core. This is utterly
counterintuitive. It means the nucleus looks like a core plus
extended diffuse cloud of neutron probability: the halo. The author
of the book, Jim Al-Khalili, is a theoretician who published some
of the key papers on the structure of the halo in the mid and late
90s and was the first to determine its true size. This monograph is
based on review articles he has written on the mathematical models
used to determine the halo structure and the reactions used to
model that structure.
