Available in PDF, EPUB and Kindle. Book excerpt: Au-delà des liquides moléculaires, une grande classe de systèmes amorphes présente les caractéristiques d'un transition vitreuse lorsque leur densité augmente: ralentissement de la dynamique et passage hors équilibre. Par ailleurs, un autre phénomène proche lui a souvent été associé : la transition de blocage (Jamming), qui intervient par exemple dans une assemblée amorphe et confinée de grains que l'on fait gonfler. A une valeur critique de la densité, la pression à l'intérieur de la boîte diverge et le matériau devient rigide.L'objectif de cette thèse est double : mieux comprendre la dynamique des particules au voisinage de la transition vitreuse d'une part, et au voisinage de la transition de blocage d'autre part.Dans une première partie, nous montrons que la transition de blocage dans un matériau granulaire dense vibré horizontalement a un comportement critique. Nous utilisons pour cela un protocole original dans lequel un intrus est tiré à force constante parmi des grains excités mécaniquement. Ce travail ouvre la voie vers des expériences de rhéologie en milieu granulaire dense.Dans une seconde partie, nous étudions comment se forment les hétérogénéités dynamiques. Pour cela, nous disposons des données de deux dispositifs expérimentaux de grains et d'une simulation d'un liquide de Lennard-Jones bidisperse répulsif, couvrant une large plage de systèmes vitreux. Malgré les apparentes différences, nous montrons que la dynamique des particules est pilotée par les mêmes mécanismes sous-jacents et mettons en évidence différentes échelles de temps ainsi qu'un mécanisme de facilitation dynamique.

Available in PDF, EPUB and Kindle. Book excerpt: The work described in this book originates from a major effort to develop a fundamental theory of the glass and the jamming transitions. The first chapters guide the reader through the phenomenology of supercooled liquids and structural glasses and provide the tools to analyze the most frequently used models able to predict the complex behavior of such systems. A fundamental outcome is a detailed theoretical derivation of an effective thermodynamic potential, along with the study of anomalous vibrational properties of sphere systems. The interested reader can find in these pages a clear and deep analysis of mean-field models as well as the description of advanced beyond-mean-field perturbative expansions. To investigate important second-order phase transitions in lattice models, the last part of the book proposes an innovative theoretical approach, based on a multi-layer construction. The different methods developed in this thesis shed new light on important connections among constraint satisfaction problems, jamming and critical phenomena in complex systems, and lay part of the groundwork for a complete theory of amorphous solids.

This book was released on 2011-07-14 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most of the solid materials we use in everyday life, from plastics to cosmetic gels exist under a non-crystalline, amorphous form: they are glasses. Yet, we are still seeking a fundamental explanation as to what glasses really are and to why they form. In this book, we survey the most recent theoretical and experimental research dealing with glassy physics, from molecular to colloidal glasses and granular media. Leading experts in this field present broad and original perspectives on one of the deepest mysteries of condensed matter physics, with an emphasis on the key role played by heterogeneities in the dynamics of glassiness.

Book excerpt: The subject of jamming and rheology is a broad and interdisciplinary one that is generating increasing interest. This book deals with one of the oldest unsolved problems in condensed matter physics - that of the nature of glass transition in supercooled liquids. Jamming and Rheology is a collection of reprinted articles from several fields, ranging from structural glasses to foams and granular materials. Glassy relaxation and constrained dynamics (jamming) occur at all scales, from microscopic to macroscopic - in the glass transition of supercooled liquids, in fluids confined to thin films, in the structural arrest of particles such as granular materials, and in foams which must be driven by an applied stress in order to flow. Because jamming occurs at the transition between where a flow occurs and where motion stops, it is hoped that there may be a universal feature that describes this transition in all systems. This volume shows that the systems described above share many common phenomenological features, and covers work done by a wide range of scientists and technologists working in areas from physics to chemistry to chemical and mechanical engineering.

Available in PDF, EPUB and Kindle. Book excerpt: With contributions from 24 global experts in diverse fields, and edited by world-recognized leaders in physical chemistry, chemical physics and biophysics, Structural Glasses and Supercooled Liquids: Theory, Experiment, and Applications presents a modern, complete survey of glassy phenomena in many systems based on firmly established characteristics of the underlying molecular motions as deduced by first principle theoretical calculations, or with direct/single-molecule experimental techniques. A well-rounded view of a variety of disordered systems where cooperative phenomena, which are epitomized by supercooled liquids, take place is provided. These systems include structural glasses and supercooled liquids, polymers, complex liquids, protein conformational dynamics, and strongly interacting electron systems with quenched/self-generated disorder. Detailed calculations and reasoned arguments closely corresponding with experimental data are included, making the book accessible to an educated non-expert reader.

This book was released on 2023-07-26 with total page 740 pages. Available in PDF, EPUB and Kindle. Book excerpt: About sixty years ago, the anomalous magnetic response of certain magnetic alloys drew the attention of theoretical physicists. It soon became clear that understanding these systems, now called spin glasses, would give rise to a new branch of statistical physics. As physical materials, spin glasses were found to be as useless as they were exotic. They have nevertheless been recognized as paradigmatic examples of complex systems with applications to problems as diverse as neural networks, amorphous solids, biological molecules, social and economic interactions, information theory and constraint satisfaction problems.This book presents an encyclopaedic overview of the broad range of these applications. More than 30 contributions are compiled, written by many of the leading researchers who have contributed to these developments over the last few decades. Some timely and cutting-edge applications are also discussed. This collection serves well as an introduction and summary of disordered and glassy systems for advanced undergraduates, graduate students and practitioners interested in the topic.

Download or read book Engineering and Physical Approaches to Cancer written by Ian Y. Wong and published by Springer Nature. This book was released on 2023-04-11 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: Engineering and Physical Approaches to Cancer addresses the newest research at this interface between cancer biology and the physical sciences. Several chapters address the mechanobiology of collective and individual cell migration, including experimental, theoretical, and computational perspectives. Other chapters consider the crosstalk of biological, chemical, and physical cues in the tumor microenvironment, including the role of senescence, polyploid giant cells, TGF-beta, metabolism, and immune cells. Further, chapters focus on circulating tumor cells and metastatic colonization, highlighting both bioengineered models as well as diagnostic technologies. Further, this book features the work of emerging and diverse investigators in this field, who have already made impressive cross-disciplinary scientific contributions. This book is designed for a general audience, particularly researchers conversant in cancer biology but less familiar with engineering (and vice-versa). Thus, we envision that this book will be suitable for faculty, postdoctoral fellows, and advanced graduate students across medicine, biological sciences, and engineering. We also anticipate this book will be of interest to medical professionals and trainees, as well as researchers in the pharmaceutical and biomedical device industry. Describes physical aspects of cancer, including collective cell migration, the aberrant tumor microenvironment, circulating tumor cells, and metastatic colonization. First volume available on the topic of physical aspects of cancer
