Coerenza Quantistica Nei Sistemi A Stato Solido

"This volume gives an overview of the manifestations of quantum coherence in different solid state systems, including semiconductor confined systems, magnetic systems, crystals and superconductors. Besides being of paramount importance in fundamental physics, the study of quantum coherence furnishes the starting point for important applications like quantum computing or secure data transmission. The coherent effects discussed mainly involve elementary excitations in solids like polaritons, excitons, magnons, macroscopic quantities like superconductor currents and electron spins. Also, several new aspects of the physics of quasi-particles are understood and discussed in this context. Due to the variety of systems in which quantum coherence may be observed, solid state systems are the natural candidates for applications that rely on coherence, for example quantum computer." --Book Jacket.

This introduction to the dissipative quantum model of brain and to its possible implications for consciousness studies is addressed to a broad interdisciplinary audience. Memory and consciousness are approached from the physicist point of view focusing on the basic observation that the brain is an open system continuously interacting with its environment. The unavoidable dissipative character of the brain functioning turns out to be the root of the brain's large memory capacity and of other memory features such as memory association, memory confusion, duration of memory. The openness of the brain implies a formal picture of the world which is modeled on the same brain image: a sort of brain copy or “Double”, where world objectiveness and the brain implicit subjectivity are conjugated. Consciousness is seen to arise from the permanent “dialogue” of the brain with its Double. The author's narration of his (re-)search gives a cross-over of the physics of elementary particles and condensed matter, and the brain's basic dynamics. This dynamic interplay makes for a “satisfying feeling of the unity of knowledge”. (Series A)

Recently, technology and aging have been key research areas in human cognition. The Research Topic “Digital Skills and Life-long Learning: Digital Learning as a New Insight of Enhanced Learning by the Innovative Approach Joining Technology and Cognition” investigated technology's impact on cognitive and intellective processes, highlighting how intensively technology can change and/or enhance the cognitive functioning throughout one’s lifespan. The aim of this Research Topic was to provide an outlook through multidisciplinary research and development while addressing the dynamic intersection of cognition, mind, and technology. Our scope was 1) to favor the cognitive technology debate, 2) to overcome the dichotomies of technology and psychology, 3) to emphasize the advances in knowledge and well-being. This Research Topic comprises review studies and original articles, focused on digital skills that enhance human potential. Transversal approaches and cross-sectorial analysis were encouraged, leading to investigation areas related to cognitive and mental processing—in educational, rehabilitation, clinical settings—across aging. Articles of high relevance to the Research Topic were submitted on the subjects of a) research in human performance and human factors, b) new research and technologies addressing the needs of a growing populace, and c) cognitive aging and cognitive rehabilitation research.

A systematic effort to rethink Freud's theory of the unconscious, aiming to separate out the different forms of unconsciousness. The logico-mathematical treatment of the subject is made easy because every concept used is simple and simply explained from first principles. Each renewed explanation of the facts brings the emergence of new knowledge from old material of truly great importance to the clinician and the theorist alike. A highly original book that ought to be read by everyone interested in psychiatry or in Freudian psychology.

This book results from a group meeting held at the Institute for Scientific Exchange in Torino, Italy. The central aim was for scientists to “think together” in new ways with those in the humanities inspired by quantum theory and especially quantum brain theory. These fields of inquiry have suffered conceptual estrangement but now are ripe for rapprochement, if academic parochialism is put aside. A prevalent theme of the book is a moving away from individual elements and individual actors acting upon each other, toward a coordinate hermeneutic dynamics that manifests as a coherent totality. Among the topics covered are image in photography and in neuroscience; language; time; brain and mathematics; quantum brain dynamics and quantum communication.

This change of perspective results in a radically new vision of how the brain functions

This text originates from the second of two conferences discussing the concept of consciousness. In 15 sections, this book demonstrates the broad range of fields now focusing on consciousness.

Offers the first overarching history of the humanities from Antiquity to the present.
