Bulk singularities at critical end points: a field-theory analysis
A class of continuum models with a critical end point is considered whose Hamiltonian H[φ, ψ] involves two densities: a primary order-parameter field, φ, and a secondary (noncritical) one, ψ. Fieldtheoretic methods (renormalization group results in conjunction with functional methods) are used to give a systematic derivation of singularities occurring at critical end points. Specifically, the t...
متن کاملA ug 1 99 9 Field - Theoretical Analysis of Singularities at Critical End Points ⋆
Continuummodels with critical end points are considered whose HamiltonianH[φ,ψ] depends on two densities φ and ψ. Field-theoretic methods are used to show the equivalence of the critical behavior on the critical line and at the critical end point and to give a systematic derivation of critical-end-point singularities like the thermal singularity ∼ |t|2−α of the spectator-phase boundary and the ...
متن کاملClusters and fluctuations at mean-field critical points and spinodals
We show that the structure of the fluctuations close to spinodals and mean-field critical points is qualitatively different from the structure close to non-mean-field critical points. This difference has important implications for many areas including the formation of glasses in supercooled liquids. In particular, the divergence of the measured static structure function in near-mean-field syste...
متن کاملInvariant Measures for Interval Maps with Critical Points and Singularities
We prove that, under a mild summability condition on the growth of the derivative on critical orbits any piecewise monotone interval map possibly containing discontinuities and singularities with infinite derivative (cusp map) admits an ergodic invariant probability measures which is absolutely continuous with respect to Lebesgue measure.
متن کاملStress-Strain Field and Theoretical Analysis of RC Bridge
In this paper, a reinforced concrete(RC) bridge built in an interchange, in the city of Kerman (a city located in south of Iran) is examined by the Structural Health Monitoring (SHM) system. During the construction of this bridge such as; the main beams, slab, and retaining walls, some Electrical Strain Gauges were mounted on the main reinforcements at different locations within the body of thi...
