Non-physical consequences of the Muffin-tin-type intra-molecular potential
We demonstrate using a simple model that in the frame of muffin-tin - like
potential non-physical peculiarities appear in molecular photoionization
cross-sections that are a consequence of jumps in the potential and its first
derivative at some radius. The magnitude of non-physical effects is of the same
order as the physical oscillations in the cross-section of a two-atomic
molecule. The role of the size of these jumps is illustrated by choosing three
values of it. The results obtained are connected to the studied previously
effect of non-analytical behavior as a function of r the potential V(r)acting
upon a particle on its photoionization cross-section. In reality, such
potential has to be analytic in magnitude and first derivative function in
distance. Introduction of non-analytic features in model potential leads to
non-physical features in the corresponding cross-section - oscillations,
additional maxima etc.Comment: 11 pages, 5 figure
Customer emotions in service failure and recovery encounters
Emotions play a significant role in the workplace, and considerable attention has been given to the study of employee emotions. Customers also play a central function in organizations, but much less is known about customer emotions. This chapter reviews the growing literature on customer emotions in employee–customer interfaces with a focus on service failure and recovery encounters, where emotions are heightened. It highlights emerging themes and key findings, addresses the measurement, modeling, and management of customer emotions, and identifies future research streams. Attention is given to emotional contagion, relationships between affective and cognitive processes, customer anger, customer rage, and individual differences
Physics over easy: Breakfasts with Beth and physics
During a sequence of meals, the author relates the principal features of physics in easy-to-understand conversations with his wife Beth. Beginning with the studies of motion by Galileo and Newton through to the revolutionary theories of relativity and quantum mechanics in the 20th century, all important aspects of electricity, energy, magnetism, gravity and the structure of matter and atoms are explained and illustrated. The second edition similarly recounts the more recent application of these theories to nanoparticles, Bose-Einstein condensates, quantum entanglement and quantum computers. B
