    Finite-Time Thermodynamics

    Traditional thermodynamics evolved from Carnot’s introduction of the concept of the ideal reversible process, a process that would proceed infi- nitely slowly. Precisely because of that constraint, such a proc...

    Phases and Phase Changes of Small Systems

    Atomic and molecular clusters exhibit a variety of phase-like forms and phase changes that differ from those of bulk matter. It is possible to relate some-but not all-of these to corresponding phases and phase...

    Phases and Phase Changes of Clusters

    Phase-like forms are expected to be observable for many kinds of clusters, insofar as they should satisfy criteria used to characterize phases of bulk form. However clusters are also expected to exhibit phase-...

    Topographies and Dynamics of Many-Dimensional Potential Surfaces

    Multidimensional potential surfaces pose a variety of problems, not least of which is that it is now possible to obtain more information about the minima and other stationary points of such surfaces than we kn...

    Exploring Potential Surface Landscapes and How they Govern Dynamics

    The subject of multidimensional potential surfaces and the dynamics on those surfaces was just reviewed by this writer 1, and the closely related topic of the analytic representation of potential surfaces, largel...

    Phase Transitions in Clusters: A Bridge to Condensed Matter

    Clusters of atoms or molecules, consisting of as few as three and as many as many thousands of particles, exhibit some properties of individual molecules, some properties of bulk matter and some properties cha...

    Pseudomolecular Electron Correlation in Atoms

    The D-dimensional scaling properties of the three-body Coulomb problem in atomic and molecular physics have been discussed in part 1 of this volume. Here we examine some new features of the adiabatic molecular...

    Steepest-Descent Quenches and the Melting of Microclusters

    Extensive molecular dynamics simulations have been performed on clusters of argon atoms to investigate the microscopic mechanism for the melting transition. The steepest-descent quench technique has been emplo...

    Melting and Freezing of Microclusters

    One of the most intriguing unsolved problems in the physical sciences is the elucidation at the atomic level of freezing and melting. Despite the great advances in the description of the critical region, the “...

    Annealing of Fine Powders: Initial Shapes and Grain Boundary Motion

    This paper describes the evolution of shapes of powder particles during the first stage of sintering, assuming initial spherical shapes. Although this model has been proposed in 1949, it is solved exactly for ...

    A General Phenomenology for Small Clusters, However Floppy

    The central topic of this Advanced Study Institute, “The Quantum Dynamics of Molecules”, is a new incarnation of a subject very old in molecular physics, the description of quantum states of molecules that do ...
