TL;DR: In this paper, the current status and dynamical approach in order to describe strange particle formation in nuclear collisions at high energy is described and a dynamical model is developed to describe the possible formation and physical properties of the quark-gluon plasma phase of hadronic matter.

TL;DR: In this article, a review of the recent progress in extracting the equation of state of hot dense hadronic matter from relativistic heavy ion collisions is presented, and a comparison of the distinct theoretical predictions to recent high multiplicity selected 4π data on fragment formation, pion production and collective sidewards flow is presented.

TL;DR: In this paper, the Casimir effect in quantum field theory and its applications is introduced and discussed in detail for specific field configurations, including supercritical fields, QCD bag models and electromagnetic media.

TL;DR: In this paper, a theory of the semiclassical evolution of wave packets is developed as a version of WKB theory in phase space, and a metaplectically covariant wave packet propagator is discussed.

TL;DR: In this paper, a review of recent developments on the Skyrme model in the context of QCD is presented, and their relevance to low-energy phenomenology is analyzed.

TL;DR: In this paper, it was shown that the anomalous U(1) symmetry of QCD can be attributed to a well-known anomaly in the regularization of the theory, which in field configurations called "instantons" can be seen to give rise to interactions that explicitly break the symmetry.

TL;DR: This review brings together the mathematical tools needed for the problem, survey the classical results, develop the quantal description, discuss the relations between the classical and quantal results, and offer some conjectures towards the diagnosis of chaoticity in quantum systems.

TL;DR: In this article, the authors examined single-mode and two-mode Gaussian pure states (GPS), quantum mechanical pure states with Gaussian wave functions, and derived many of the important properties of GPS and of the Hamiltonians and unitary operators associated with them.

TL;DR: In this article, various techniques for computing the fractional fermion number of topological solitons are reviewed, and the connections between the FPN calculation and the general properties of the spectrum, in particular spectral asymmetry of the pertinent Dirac operator are exposed.

TL;DR: A review of the wide variety of predictions that results from a Landau-type of description of the nematic-isotropic phase transition is given in this paper, which includes a discussion of the nature of the order parameter and of the various types of possible phases.

TL;DR: Theoretical models for the dynamics of the formation and emission of these clusters of nucleons are reviewed in this paper, but not all of them are statistical in origin, following from the assumption that the phase space available for cluster formation and emissions is the dominant factor.

TL;DR: The paper begins with an introduction to the field of growth models showing what makes them different from stalic models and a principal role in these relations plays the fractal dimension.

TL;DR: In this article, a review of analytical and numerical work on confinement phase transitions in finite-temperature Abelian and non-Abelian gauge theories is presented, and the role of matter fields as symmetry-breaking perturbations is noted as important to the eventual unraveling of the phase structure of quantum chromodynamics.

TL;DR: In this paper, a review of recent data on the production of pions and strange particles at the Bevalac and Synchrophasotron accelerators is presented, covering pion spectra and multiplicity distributions, λ, K+ and K− yields and spectra, and Λ polarization.
