Available in PDF, EPUB and Kindle. Book excerpt: The 1984 Cargese Advanced Study Institute was devoted to the study of nuclear heavy ion collisions at medium and ultrarelativis tic energies. The origin of this meeting goes back to 1982 when the organizers met at the GANIL laboratory in Caen, France which had just started accelerating argon ions at 44 MeV per nucleon. We then realized that 1984 should be the appropriate time to review the first results obtained with such new kinds of facilities. The material contained in this volume, presenting many beautiful re sults on nuclei at high excitation, fully confirms this point. Many stimulating exchanges between experts in rather diffe rent fields already took place during the school and we hope that this cross fertilization will lead to further developments. About half of the present volume is also devoted to the field of relativistic heavy ion collisions, which is now expanding rapidly. As an illustration, let us recall that the construction of a 30 on 30 GeV per nucleon collider at Brookhaven has been recognized last year as one cf the major priorities by the US Nuclear Science Advisory Committee. We would like to express our gratitude to NATO for its ge nerous financial support which made this institute possible. We also wish to thank the Institut de Physique Nucleaire et de Physique des Particules (France), the Commissariat a l'energie atomique (France) and The National Science Foundation (USA) for the attribution of travel grants.

Available in PDF, EPUB and Kindle. Book excerpt: This book is designed for advanced undergraduate and graduate students in high energy heavy-ion physics. It is relevant for students who will work on topics being explored at RHIC and the LHC. In the first part, the basic principles of these studies are covered including kinematics, cross sections (including the quark model and parton distribution functions), the geometry of nuclear collisions, thermodynamics, hydrodynamics and relevant aspects of lattice gauge theory at finite temperature. The second part covers some more specific probes of heavy-ion collisions at these energies: high mass thermal dileptons, quarkonium and hadronization. The second part also serves as extended examples of concepts learned in the previous part. Both parts contain examples in the text as well as exercises at the end of each chapter. - Designed for students and newcomers to the field- Focuses on hard probes and QCD- Covers all aspects of high energy heavy-ion physics- Includes worked example problems and exercises

Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, we aim to advance the time-dependent transport theories for the description of heavy-ion collisions, from two perspectives. As an attempt to address multifragmentation in nuclear collisions, we develop a stochastic transport model based on one-body Langevin dynamics. The new model is subsequently tested and benchmarked with a series of other existing models with satisfaction. The model is also applied to address and confirm the so-called "hierarchy effect" observed in the multifragmentation for certain systems around Fermi energies. Parallel to the development towards a stochastic theory, we also extend an approach based on non-equilibrium Green's function for the description of correlated nuclear systems in one dimension.Firstly, we present a new framework to treat the dissipation and fluctuation dynamics associated with nucleon-nucleon scattering in heavy-ion collisions. The two-body collisions are effectively described in terms of the diffusion of nucleons in viscous nuclear media, governed by a set of Langevin equations in momentum space. The new framework combined with the usual mean-field dynamics, forming the basis of the new stochastic model, can be used to simulate heavy-ion collisions at intermediate energies.Subsequently, as a proof of principle for the new model, we simulate Au + Au reactions 100 MeV/nucleon and at 400 MeV/nucleon and look at observables such as rapidity distribution and flow as a function of rapidity. The results are found to be consistent with other existing models under the same constrained conditions. To demonstrate the model's ability to describe multifragmentation, we also study the formation of fragments in Sn +Sn reactions at 50 MeV/nucleon, and the fragment distribution and properties are discussed and compared to two other models commonly employed for collisions.Next, we move on to tackle the "hierarchy effect" observed experimentally for reactions around Fermi energies. We simulate Ta + Au at 39.6 MeV/nucleon and compare mainly the charge and velocity distributions of the fragments from the QP with experimental data. Our simulation results can reproduce the trends observed in data, and a semi-quantitative agreement can be reached. This is the first time, to our knowledge, that one has succeeded in addressing the "hierarchy effect" with a dynamic model. The simulation of U + C is also discussed.Finally, we present a fully quantum-mechanical model based on non-equilibrium Green's function, with short-range two-body correlations incorporated as an extension. We examine its applications to one-dimensional nuclear systems, such as the preparation and properties of the ground states, the isovector oscillation of symmetric systems and the boosting of a"slab" in a periodic box. In particular, the dissipation brought by two-body correlations and the Galilean covariance of the theory are demonstrated. These studies lay the groundwork for the future exploration of collisions of correlated nuclear systems in one dimension.

Available in PDF, EPUB and Kindle. Book excerpt: The effect of the nuclear equation of state on high-energy heavy-ion collisions is studied in two separate ways on the basis of conventional nuclear fluid dynamics. The equation of state has the property that the speed of sound approaches the speed of light in the limit of infinite compression. In the first way, nonrelativistic equations of motion are solved for various values of the nuclear compressibility coefficient for the expansion of spherically symmetric nuclear matter. The matter is initially compressed and excited in head-on collisions of equal targets and projectiles at a laboratory bombarding energy of 250 MeV/A. When the matter expands to a freezeout density, the remaining thermal energy is superimposed in terms of a Maxwell-Boltzmann distribution. The resulting energy distributions for different values of the compressibility coefficient are similar to one another, but they are significantly different from a Maxwell-Boltzmann distribution corresponding to entirely thermal energy and moderately different from the energy distribution corresponding to the Siemens-Rasmussen approximation. In the second way, relativistic equations of motion are solved numerically in three spatial dimensions for the reaction 2°Ne + 238U at a laboratory bombarding energy per nucleon of 393 MeV/A, both with and without a density isomer. The double-differential cross section d2sigma/dEd.cap omega. corresponding both to all impact parameters and to central collisions constituting 15% of the total cross section is computed. The results for the various equations of state are very similar to one another except for central collisions at laboratory angle theta = 30° and for both central collisions and all impact parameters at theta = 150°. In these cases, over certain ranges of energy, d2sigma/dEd.cap omega. is larger for the density isomer than for conventional equations of state. 8 figures.

Available in PDF, EPUB and Kindle. Book excerpt: This book brings together various aspects of the nuclear fission phenomenon discovered by Hahn, Strassmann and Meitner almost 70 years ago. Beginning with an historical introduction the authors present various models to describe the fission process of hot nuclei as well as the spontaneous fission of cold nuclei and their isomers. The role of transport coefficients, like inertia and friction in fission dynamics is discussed. The effect of the nuclear shell structure on the fission probability and the mass and kinetic energy distributions of the fission fragments is presented. The fusion-fission process leading to the synthesis of new isotopes including super-heavy elements is described. The book will thus be useful for theoretical and experimental physicists, as well as for graduate and PhD students.

Available in PDF, EPUB and Kindle. Book excerpt: The mesoscopic domain encompasses structures that are best described in terms of the time and length scales which lie between the two extremes of the molecular and the phenomenological description of materials. Important examples of such structures are self-assemblies, emulsions, gels, colloids aggregates and macromolecules networks. Discussing the key advances made in recent years in our understanding of both equilibrium and dynamic aspects of mesoscopic structures, most talks at the conference were given by world class researchers in the field, who included, among others, Prof J S Higgins, CBE, FRS (Imperial College, London), Prof D Frenkel (FOM, Amsterdam), Prof M E Cates (Edinburgh), Prof R C Ball (Warwick), Prof S Ramaswamy (Indian Institute of Science, Bangalore), Prof R Pandit (Bangalore), Dr J A Yeomans (Oxford), Prof S Puri (JNU, New Delhi), Dr D Langevin (CRPP, Bordeaux), and Prof W G M Agterof (Unilever Research, Vlaardingen).
