TL;DR: In this article, the authors demonstrate the mechanism for a universal instability, the Arnold diffusion, which occurs in the oscillating systems having more than two degrees of freedom, which results in an irregular, or stochastic, motion of the system as if the latter were influenced by a random perturbation even though, in fact, the motion is governed by purely dynamical equations.

TL;DR: In this article, the scaling theory of phase transition has been used to explain percolation through the cluster properties; it can also be used as an introduction to critical phenomena at other phase transitions for readers not familiar with scaling theory.

TL;DR: In this article, the doublefolding model was used to calculate the real part of the optical potential for heavy-ion scattering, and the resulting potentials were shown to reproduce the observed elastic scattering for a large number of systems with bombarding energies from 5 to 20 MeV per nucleon.

TL;DR: In this paper, the effects of weak neutral currents is nuclei and show how different nuclear processes can sensitively test gauge theory models of the weak and electromagnetic interactions, although one chapter of their review is devoted to weak neutral current effects in polarized electron scattering off nuclei.

TL;DR: In this paper, path integrals for path on curved spaces and for paths on multiply-connected spaces are computed explicitly and applied to problems in nonrelativistic quantum mechanics, such as wave functions, propagators on configuration spaces and on phase space, caustic problems, bound states.

TL;DR: In this paper, infinite density singularities may be shown to occur in Friedmann-Robertson-Walker universes and orthogonal spatially homogeneous universes, but very different behaviours are possible in tilted homogeneous cosmologies.

TL;DR: In this paper, the generalized van der Waals theory is used to study infinitesimal density fluctuations and their relation to the stability of the single phase fluid state and critical opalescence.

TL;DR: In this paper, a systematic account of relativistic many-body theory is presented with particular emphasis on the renormalization of finite temperature and density Green's functions and the thermodynamic potential, which is then applied to Quantum Chromodynamics (QCD), the non-Abelian gauge theory of the strong interaction (quarks and gluons), to demonstrate the applicability of perturbation theory of strong force at high baryon number densities.

TL;DR: A comprehensive survey of diffusion studies in solids can be found in this paper, where the authors discuss the meaning and significance of what is currently known about diffusion in molecular crystals and the point defect structure of these solids.

TL;DR: In this article, the authors apply modern mathematical methods of global analysis to a series of studies undertaken by Belinskii, Khalatnikov and Lifschitz (BKL) to elucidate the structure of space-time near a general cosmological singularity.

TL;DR: In this paper, a review of the derivation of exact S -matrices in field theoretic models with soliton behaviour is given, that means models obeying infinitely many conservation laws which imply the factorization of the S -Matrix.
