Gardner Transition
In condensed matter physics, the Gardner transition refers to a temperature induced transition in which the free energy basin of a disordered system divides into many marginally stable sub-basins. It is named after Elizabeth Gardner who first described it in 1985. See also *Glass transition The glass–liquid transition, or glass transition, is the gradual and reversible transition in amorphous materials (or in amorphous regions within semicrystalline materials) from a hard and relatively brittle "glassy" state into a viscous or rub ...

Condensed Matter Physics
Condensed matter physics is the field of physics that deals with the macroscopic and microscopic physical properties of matter, especially the solid and liquid phases which arise from electromagnetic forces between atoms. More generally, the subject deals with "condensed" phases of matter: systems of many constituents with strong interactions between them. More exotic condensed phases include the superconducting phase exhibited by certain materials at low temperature, the ferromagnetic and antiferromagnetic phases of spins on crystal lattices of atoms, and the Bose–Einstein condensate found in ultracold atomic systems. Condensed matter physicists seek to understand the behavior of these phases by experiments to measure various material properties, and by applying the physical laws of quantum mechanics, electromagnetism, statistical mechanics, and other theories to develop mathematical models. The diversity of systems and phenomena available for study makes condensed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elizabeth Gardner (physicist)
Elizabeth Gardner (25 August 1957 – 18 June 1988) was a British theoretical physicist. She is best known for her groundbreaking work on a phase transition known as the Gardner transition and on disordered networks. Early life and education Gardner was born in Cheshire, UK. Both of her parents were chemical engineers. Gardner was interested in science from an early age. In 1975, she enrolled in University of Edinburgh to study mathematical physics. She graduated with first class honors, and was awarded the Tait Medal in 1979, Robert Schlapp Prize, and the Class medal. Gardner completed her D.Phil. studies at Oxford under the supervision of I.J.R. Aitchison. Her thesis was in particle physics, and focused on non-Abelian gauge theories. Despite fulfilling requirements, Gardner did not formally graduate from Oxford. Career Following her D.Phil., Gardner moved to the Saclay Nuclear Research Centre, where she spent two years, supported by a Royal Society Fellowship. She work ...

Glass Transition
The glass–liquid transition, or glass transition, is the gradual and reversible transition in amorphous materials (or in amorphous regions within semicrystalline materials) from a hard and relatively brittle "glassy" state into a viscous or rubbery state as the temperature is increased. ISO 11357-2: Plastics – Differential scanning calorimetry – Part 2: Determination of glass transition temperature (1999). An amorphous solid that exhibits a glass transition is called a glass. The reverse transition, achieved by supercooling a viscous liquid into the glass state, is called vitrification. The glass-transition temperature ''T''g of a material characterizes the range of temperatures over which this glass transition occurs (as an experimental definition, typically marked as 100 s of relaxation time). It is always lower than the melting temperature, ''T''m, of the crystalline state of the material, if one exists. Hard plastics like polystyrene and poly(methyl methacrylate) ar ...
