Excitations in Simple Liquids, Liquid Metals and Superfluids

This book is written with the experimentalist in the field of liquids in mind. The rapid increase in capabilities at neutron and x-ray scattering sources has resulted in a wealth of highly accurate data on liquids, allowing for the testing of sophisticated models pertinent to the microscopic dynamics. This book is a practical guide on how to infer the maximum amount of information from the data using a minimum number of parameters, employinga fail-safe framework that ensures that pitfalls are avoided and that small differences between various liquids can be uncovered. Also, it details excitations for a range of liquids, covering simple fluids, colloids, mixtures, metals and superfluids. Results are interpreted in words rather than inequations, bringing to the fore new links between these fluids and between spontaneous fluctuations involving thousands of atoms down to those involving just a few.

Wouter Montfrooij was an Instrument Scientist on the MARI spectrometer at the ISIS facility of the Rutherford Appleton Laboratories (1995-1998), before taking postdoc positions at Atomic Energy of Canada, Chalk River, Ontario, Canada, at Risø National Laboratory, Roskilde, Denmark and at Oak Ridge National Laboratory, Oak Ridge TN, USA. He is now Associate Professor of Physics at the University of Missouri, Columbia MO, USA.

Ignatz de Schepper was a postdoctoral researcher at the Rockefeller University, New York, before becoming Lecturer of Theoretical Physics, University of Utrecht, the Netherlands. He later became Head of the Neutron Scattering Group, Interfaculty Reactor Institute, Technical University Delft, Delft, the Netherlands. He is now Professor Emeritus of Radiation Physics.
