The magnetic moment of a single impurity atom in a finite free electron gas is studied in a combined x-ray magnetic circular dichroism spectroscopy, charge transfer multiplet calculation, and density functional theory study of size-selected free chromium-doped gold clusters. The observed size dependence of the local magnetic moment can be understood as a transition from a local moment to a mixe...
Abstract To illustrate Boltzmann’s construction of an entropy function that is defined for a microstate macroscopic system, we present here the simple example free expansion one dimensional gas non-interacting point particles. The requires to define macrostates, corresponding variables. We macrostate M by specifying fraction particles in rectangular boxes Δ x v single particle position-velocity...
Abstract. In this work we deal with the no-slip drift-flux model for gas-liquid flow dynamics. We focus on a situation where there is a free interface separating the gas-liquid mixture from a pure gas region which takes a positive pressure p∗. This situation is highly relevant for gas-liquid flow in the context of wellbore operations. Previous works have assumed that there is vacuum, i.e., the ...
