Physical adsorption involves atomic or molecular films bound to surfaces by less than 0.5 eV per particle (10 kcal/mole). The subject has attracted wide interest because these films exhibit behavior characteristic of two-dimensional matter. The phase diagrams of these films are diverse and often rich in structure because of the competing energy and length scales of the two interactions involved in this problem: the mutual interaction between adsorbed molecules and the force binding each molecule to the surface. This book describes our current understanding of these phenomena from a fundamental perspective. After explaining the microscopic origin of these forces in terms of constituent electrons, the text describes how statistical mechanical theory and computer simulation employ these forces to calculate the structural and dynamical properties of the films. Throughout the book comparison is made with many relevant experiments. Unique in its field, this book will be of interest to students and both academic and industrial researchers in chemistry, engineering and physics.

A comprehensive account of the phenomena that occur when simple gases interact with surfaces, this text takes a fundamental perspective. Physical adsorption involves atomic or molecular films bound to surfaces by less than 0.5 eV per particle. Physically absorbed thin films exhibit remarkably diverse properties and behave in a manner characteristic of two-dimensional matter. This exploration focuses on monolayer physics, emphasizing atomic rather than molecular adsorption.The phase diagrams of physically absorbed films are diverse and rich in structure because of the subtle and varied competition between the two interactions: the mutual interaction between adsorbed molecules, and the force binding each molecule to the surface. The authors explain the microscopic origin of these forces in terms of constituent electrons and nuclei. They then examine the structural and dynamical properties of these films in the context of atomic and solid-state physics, statistical mechanics, and computer simulations.This text will be of interest to research chemists, physicists, and engineers alike, as well as students in these fields. Key literature citations allow readers to trace important developments, and thought-provoking problems are addressed in detail.

The discovery of Bose-Einstein condensation (BEC) in trapped ultracold atomic gases in 1995 has led to an explosion of theoretical and experimental research on the properties of Bose-condensed dilute gases. The first treatment of BEC at finite temperatures, this book presents a thorough account of the theory of two-component dynamics and nonequilibrium behaviour in superfluid Bose gases. It uses a simplified microscopic model to give a clear, explicit account of collective modes in both the collisionless and collision-dominated regions. Major topics such as kinetic equations, local equilibrium and two-fluid hydrodynamics are introduced at an elementary level. Explicit predictions are worked out and linked to experiments. Providing a platform for future experimental and theoretical studies on the finite temperature dynamics of trapped Bose gases, this book is ideal for researchers and graduate students in ultracold atom physics, atomic, molecular and optical physics and condensed matter physics.
