Supercooled liquids become increasingly sluggish upon cooling down to the glass temperature T g where they can no longer be studied in equilibrium on the laboratory scale and behave as off-equilibrium amorphous solids, i.e., glasses. Simple activated dynamics account for the behavior of so-called strong liquids, but deviations from Arrhenius behavior ...

Physica B+C, 1982
The superfluid transition in liquid 4He provides a unique system for testing the modern theory of critical phenomena, and for determining whether it is indeed an exact theory in real materials. Static predictions concerning the superfluid density and the specific heat are described, and are shown to yield impressive agreement with experiment, in all ...

Physical Review B, 1976
This paper proposes an approach to the study of critical phenomena in quantum-mechanical systems at zero or low temperatures, where classical free-energy functionals of the Landau-Ginzburg-Wilson sort are not valid. The functional integral transformations first proposed by Stratonovich and Hubbard allow one to construct a quantum-mechanical ...

Publisher Summary This chapter provides a heuristic introduction to scaling procedures that characterize properties of systems close to their critical point. The objective is to provide some general insights, and to convey the flavor of the methodology.

Gelation and critical phenomena [PDF]
, 2007 For the critical exponents near the sol-gel phase transition, classical theories like those of Flory and Stockmayer predict one set of exponents, whereas scaling theories based on lattice percolation predict different exponents. The two groups of theories differ in their treatment of intramolecular loops, space dimensionality and excluded volume ...

Critical Phenomena: a Reminder [PDF]
, 1999 We begin by recalling some basic facts about critical phenomena. This is not intended to provide a complete and exhaustive introduction to the field. We rather put emphasis on those standard concepts which will form the basis for the extension to conformal invariance in later chapters. Besides this, we establish our notation.

Isomorphism in critical phenomena
Chemical Physics Letters, 1979Abstract A dielectric liquid in a low external field is considered from the point of view of the effect of hidden variables on critical thermodynamic functions. Isomorphism is satisfied within scaling theory.

In general a solid-solid phase boundary does not terminate in a critical point due to symmetry requirements. However, there exists systems like pure cerium metal and rare earth compounds like samarium sulphide where an isostructural solid-solid phase boundary terminates at a critical point.

Critical phenomena at interfaces
Physica A: Statistical Mechanics and its Applications, 1990Abstract The interface between two phases may exhibit significant structural changes if one of them comes close to a phase transition in its bulk. Irrespective of the order of the bulk transition these structural changes of the interfaces manifest as critical phenomena of their own linking the space dimensions two and three.
