TL;DR: In this article, the theory of first order Fermi acceleration at collisionless astrophysical shock fronts is reviewed and it is argued that the wave amplitude is probably non-linear within sufficiently strong astrophysical shocks.

TL;DR: In this article, the physics of light pseudoscalars (axions, majorons and familons) and their effects in cosmology are reviewed. And the allowed band of the axion scale 10 8 GeV ≲ F a ≲ 10 12 GeV is discussed.

TL;DR: In this article, the authors present a review of continuous-time random walk theory for diffusion of single particles on lattices with frozen-in disorder, including models with regular transition rates and irregular lattices.

TL;DR: In this paper, a detailed account of relativistic quantum field theory in the grand canonical ensemble is given, where three approaches are discussed: traditional Euclidean Matsubara, and two recently developed real-time methods, namely, Minkowskian time-path and thermo field dynamics.

TL;DR: In this paper, the authors describe anomalous scaling in terms of multifractal objects, defined by a measure whose scaling properties are characterized by a family of singularities, which are identified by a scaling exponent.

TL;DR: In this article, the authors present a methodology that relates the kinetics of material failure on the microstructural level to continuum mechanics, by introducing micro-structural descriptions of damage into the continuum constitutive relations as internal state variables.

TL;DR: In this article, the authors discuss the structure, physical properties, and implications of no-scale supergravity models and study in considerable detail all the basic ingredients that come to play in their structure, such as supersymmetry and supergravity.

TL;DR: In this paper, the current status of the theoretical developments in the study of the interparticle correlations in dense plasmas and the transport and elementary processes is reviewed, and specific features considered are the strong Coulomb-coupling effects in the dense ion systems, the varied degrees of Fermi degeneracy in the electron systems and the mutual coupling between the ion and electron systems.

TL;DR: In this paper, the authors discuss the direct methods that can be used to search for the second invariant of a system defined by the Hamiltonian H = 1 2 (p x 2 ) + p y 2 + A(x, y)p x + B(x and y), p y + V(x, y).

TL;DR: The formalism and results of truncated coupled channels evaluations of three-body models of deutron-induced nuclear reactions are reviewed in this article, with emphasis on breakup, elastic scattering and stripping.

TL;DR: In this article, the authors study the open-shell coupled-cluster theories and examine the current theoretical status regarding the existence or non-existence of a linked-clusters theorem, ensuring the connectedness of the cluster amplitudes and the effective Hamiltonian.

TL;DR: In this paper, the relativistic Dirac-Brueckner approach was used to study the properties of both dense and hot symmetric nuclear matter, and the saturation point was found to lie on a Coester line which goes through the empirical value for nuclear matter.

TL;DR: In this paper, a comprehensive calculation of core-polarisation, meson-exchange current and isobar-current corrections to low-energy M1 and Gamow-Teller transitions in closed-shell-plus-one nuclei (at LS and jj closed shells) is presented.

TL;DR: In this paper, the authors present analytical and numerical results on the mechanism of excitation and ionization of hydrogen atoms under microwave fields, and they predict the existence of a critical value of the microwave field, the quantum delocalization border, above which the quantum packet delocalizes and strong ionization takes place.

TL;DR: In this paper, the Compton-getting interpretation of the dipole anisotropy in the microwave background is presented as a diagnostic of the weak asymmetry exhibited by the cosmic X-ray background.

TL;DR: A quantum Boltzmann equation for electron transport in electric and magnetic fields including all many-body effects is derived in this article, and a solution in both d.c and a.c. electric fields is given for electrons in simple metals.

TL;DR: In this article, the KMS condition of quantum statistical mechanics is derived, with special attention to quantum field systems satisfying relativistic commutation relations and linear field equations, and the application of these ideas to horizons in general-relativistic settings is reviewed.

TL;DR: In this article, the planar expansion of a plasma into vacuum is investigated numerically and analytically based on the hydrodynamic description, and several dynamical structures are found and explained.

TL;DR: In this paper, the results of experimental study of hyper-Raman scattering by phonons and polaritons in centrosymmetric and non-centroidal crystals, inorganic oxide glasses and molecular liquids are discussed.

TL;DR: In this article, a review of the properties of the solid state, the liquid state, and interfaces at the freezing point is given, which can be described by laws of corresponding states, so-called melting rules.

TL;DR: Two-dimensional classical chiral models of field theory are considered, the main attention being paid on geometrical aspects of such theories, which are in many respects analogous to non-Abelian gauge theories and important for the superstring theory.

TL;DR: In this paper, the authors review some aspects of the theory of moduli spaces which have recently become important in string theory and discuss infinities in string theories and their interpretation in terms of the boundary of the moduli space following Belavin and Knizhnik.

TL;DR: In this paper, the authors review the phenomenology, techniques, and results of particle-physics experiments that are performed beyond the confines of accelerator laboratories, and present a review of particle physics experiments performed in the wild.
