Book Description
The properties of the liquid metals are of great interest both because of their fundamental importance as well as their engineering applications. Considering a fact that local pseudopotentials offer mathematical ease, non-local pseudopotentials are to be preferred for correct assessment of the physical properties. However, with an intension to include features of the non-locality into the local potential formulation, a modified empty core potential was used.We believe that the present estimates for different thermo-elastic properties may serve as good starting point and the guideline for future study, and provide means of comparison for the dynamical phenomena. Present study also brings the fact that the properties are sensitive to temperature, so its temperature variation is therefore a clue to understand temperature variation of elastic properties. Thus, in the absence of experimental results at high temperatures such calculations may be considered as the guideline for further theoretical or experimental investigations.

Book Description
Our understanding of the liquid (or molten) state of metals has progressed far within the past decades. Thanks to the advances in both x-ray and neutron scattering sources, it is now possible to measure the dynamics on a microscopic scale with very good statistical accuracy. The dynamics given by a single particle in a liquid metal owe to self-diffusion and cage diffusion. Presented are quasielastic neutron scattering studies of various liquid metals at low momentum transfers. The first part of this thesis is devoted to the investigation of a new (and unpredicted) contribution to the hydrodynamics of liquid metals. We present a literature review of published experiments to verify the presence of this new mode in liquid metals, followed by a possible explanation for its presence in terms of collision-induced magnetism. Next, we present a neutron scattering study at low momentum transfers using liquid gallium to verify the existence of this new contribution. The contribution turns out to be non-magnetic in origin, so another set of neutron scattering experiments is carried out, determining that the contribution should be attributed to multiple scattering processes in liquid gallium (though these same experiments suggest that this contribution is not a multiple scattering effect in liquid lead and mercury). In the last chapters of the thesis we investigate the potential effects of quantum mechanical diffraction effects on the collision between two ions. To carry out the investigation, we solved the collision between two almost classical particles using the partial wave method. We calculate the importance of this diffraction mechanism in liquid metals and present their influence on the neutron scattering cross-section when measuring the collision between two ions, given by an oscillation in the scattering cross-section.

Book Description
Liquid Metals covers topics about the properties of liquid metals, with emphasis on the microscopic description of the electron states. The book discusses radial distribution function, which is the quantitative way by which the structure of a monatomic fluid may be described, and the scattering of X-rays (or neutrons) from the fluid. The text describes the way by which the forces operating in liquid metals may be qualitatively described; the theory of electron screening in metals; the shielding of a structureless ion core in the Born approximation; and ways by which the structure of the ion core can profoundly influence the shielding. The forces operating between ions in liquid metals; the properties of solid metals; the time-dependent generalization of the structure factor; the dynamics of fluids from inelastic neutron scattering; and the nature of the energy level spectrum of the electrons in a liquid metal are also considered. Students of elementary quantum mechanics and statistical thermodynamics and physicists will find the book invaluable.

Book Description
This 1972 book brings together the results of a decade of research into the physics of liquid metals and alloys, a subject of growing interest to physicists, metallurgists and materials scientists at the time. It covers a wide range of phenomena, and for the benefit of newcomers to the field, Dr Faber provides a clear exposition of the physical properties involved, and the relevant theoretical arguments are developed in sufficient detail for an experimentalist who carries rather little in the way of mathematical equipment to follow them. Experienced researchers will appreciate Dr Faber's critical approach and the many previously unpublished results which he has included. The mass of experimental data which he has brought together and the comprehensive bibliography will make the book of great use to readers of both classes.

Book Description
Comprehensive coverage of topics in the theory of classical liquids Widely regarded as the standard text in its field, Theory of Simple Liquids gives an advanced but self-contained account of liquid state theory within the unifying framework provided by classical statistical mechanics. The structure of this revised and updated Fourth Edition is similar to that of the previous one but there are significant shifts in emphasis and much new material has been added. Major changes and Key Features in content include: - Expansion of existing sections on simulation methods, liquid-vapour coexistence, the hierarchical reference theory of criticality, and the dynamics of super-cooled liquids. - New sections on binary fluid mixtures, surface tension, wetting, the asymptotic decay of pair correlations, fluids in porous media, the thermodynamics of glasses, and fluid flow at solid surfaces. - An entirely new chapter on applications to 'soft matter' of a combination of liquid state theory and coarse graining strategies, with sections on polymer solutions and polymer melts, colloidal dispersions, colloid-polymer mixtures, lyotropic liquid crystals, colloidal dynamics, and on clustering and gelation. - Expansion of existing sections on simulation methods, liquid-vapour coexistence, the hierarchian reference of criticality, and the dynamics of super-cooled liquids. - New sections on binary fluid mixtures, surface tension, wetting, the asymptotic decay of pair correlations, fluids in porous media, the thermodynamics of glasses, and fluid flow at solid surfaces. - An entirely new chapter on applications to 'soft matter' of a combination of liquid state theory and coarse graining strategies, with sections on polymer solutions and polymer melts, colloidal dispersions, colloid-polymer mixtures, lyotropic liquid crystals, colloidal dynamics, and on clustering and gelation.

Book Description
This book provides the first comprehensive critical survey of the microstructural characteristics of liquid metals which determine properties of viscosity, surface tension, density, heat capacity, thermal conductivity, electrical resistivity, diffusion, and velocity of sound transmission. The experimental techniques used to obtain these data are also reviewed. The result is a valuable set of correlations and reference data which enable the reader to understand the basic phenomena underlying the properties of liquid metals. As such, the book will be invaluable for metallurgists and materials engineers working in this area.

Book Description
This comprehensive, research level introduction to the theory of liquid metals presents the concepts needed to understand the properties of these metals starting with a survey of the basic experimental facts. The quantitative theory of liquid pair correlation functions, effective ion-ion interactions, thermodynamic properties and electronic and atomic transport is then developed. The book also explores inelastic neutron scattering from bulk liquid metals, critical behavior, magnetism, the present understanding of the liquid metal surface, binary liquid metals, shock wave studies, liquid hydrogen plasmas and the constitution of red star giants. This is an informative text for advanced postgraduate students and researchers in condensed matter physics, theoretical physics, physical chemistry and theoretical chemistry.
