This volume contains invited and contributed papers delivered at a symposium on the occasion of Professor Glauber's 60th birthday. The papers, many of which are authored by world leaders in their fields, contain recent research work in quantum optics, statistical mechanics and high energy physics related to the pioneering work of Professor Roy Glauber; most contain original research material that is previously unpublished. The concepts of coherence, cooperativity and fluctuations in systems with many degrees of freedom are a common base (...) for all of Professor Glauber's research initiatives and, in fact, for much of contemporary physics. His role in shaping these cconcepts is reflected and honoured in the papers contained in this book. (shrink)

The spectral fluctuations of quantum (or wave) systems with a chaotic classical (or ray) limit are mostly universal and faithful to random-matrix theory. Taking up ideas of Pechukas and Yukawa we show that equilibrium statistical mechanics for the fictitious gas of particles associated with the parametric motion of levels yields spectral fluctuations of the random-matrix type. Previously known clues to that goal are an appropriate equilibrium ensemble and a certain ergodicity of level dynamics. We here complete the reasoning by establishing (...) a power law for the ħ dependence of the mean parametric separation of avoided level crossings. Due to that law universal spectral fluctuations emerge as average behavior of a family of quantum dynamics drawn from a control parameter interval which becomes vanishingly small in the classical limit; the family thus corresponds to a single classical system. We also argue that classically integrable dynamics cannot produce universal spectral fluctuations since their level dynamics resembles a nearly ideal Pechukas–Yukawa gas. (shrink)

This article points out, descriptive moral psychology of human behavior patterns in the handling, in fact, from the outset exceed the boundaries of philosophy, and Cole tried to resort to ethics Fort formalism in order to avoid this problem in practice, can not be established. • Henry Rachael is further motivation for ethical behavior and the psychological concept of Cole Castle together. Although this is certainly an important contribution to the Fort Cole, but Cole Fort critical reflection on the lack (...) of methodology adopted only; secondly that the ideology behind their psychological factors; finally made ​​sense to remedy in the treatment program: to give up on life and psychological describe their condition or results of work. Authors propose a new proposal of psychology, first identified the relationship between psychologists and their research object, this object is, as the subject of people; secondly, from the possibility of speech. Description, either by himself or a third person described in the description, will be replaced by speech interaction. Authors proposed the concept of an interactive framework of doctrine, in which Cole and Rachael • Fort Henry's theory of language games can get a different position. This article attempts to demonstrate that the descriptive psychology, in its treatment of ethical problems, seems to have transgressed the boundary line against philosophy. This problematic situation cannot be circumvented by resorting to an ethical formalism-as L. Kohlberg does in his research program. Rachael M. Henry pushes one step forward to tie the psychodynamic aspect of moral behavior with Kohlberg's concept. The present author, all in affirming the important contribution of Kohlberg to psychology, indicates the insufficiency of a mere reflection of methods in Kohlberg's works. Then he dissects the ideologemes behind Kohlberg's psychology. At last he suggests a therapeutic proposal: the demand for describing psychic life, its conditions or effects, shall be dropped. The author proposes instead a program of new psychology that derives first from the relation of psychologist to his object, the human as subject; and second, from the possibilities of speech in communicative interaction. Description, whether made by oneself or by a third person, shall be substituted by speech interactions. These interactions are considered as successful when the partners in a discussion declare themselves to be understood. Within the framework of this interactionist concept, Kohlberg's and Rachael M. Henry 's theories could assume the status of various language-games. (shrink)
