Critical exponent for viscosity

Physical Review A, 1990
The critical exponent y characterizing the divergence of the viscosity for carbon dioxide and xenon has been measured. The values of y for both fluids fall within the range y = 0.041 + or - 0.001 and are consistent with the range y = 0.042 + or - 0.002 spanned by earlier data for four binary liquid mixtures.

Localization Critical Exponents [PDF]

, 1991
The problem of Anderson localization has generated intense interest for over three decades. It can serve as a simple model for understanding the dynamics of vibrational or electronic excitons in molecular and inorganic crystals, as well as the transport of electrons in doped semiconductors.

Biopolymer gelation- exponents and critical exponents

Polymer Bulletin, 2006
The gelation of biopolymer systems has been studied, at least, empirically for many years, but only more recently have the methods of macromolecular science been applied. A number of following studies have tended to concentrate on measuring power law exponents, and have ignored details of the network structure.

Critical exponents of FeBO3

AIP Conference Proceedings, 1975
A sample of FeBO3 containing 1‐5 μm diameter platelets was prepared. Magnetic measurement were made using a vibrating coil magnetometer and fields of 0.1 to 5 kOe. Data analysis included the effect of crystallite alignment and corrections for the small demagnetizing field. The Curie temperature was found to be 347.85±0.2 K.

Critical exponents of the gauge glass

Physical Review B, 1988
The spin-glass phase suggested for granular superconductors in an externally applied magnetic field is discussed in detail. The spin-glass order parameter is an n\ifmmode\times\else\texttimes\fi{}n, n\ensuremath{\equiv}0 Hermitian matrix. As a consequence, we show, by explicit calculation of the critical exponents to order \ensuremath{\epsilon}=6-d ...

Paramagnetic critical exponents

Physica B+C, 1988
Abstract Critical point exponents for the paramagnetic susceptibility in Co and Fe have been derived from the measurements published by Develey. The exponent, γ, for the linear reduced temperature (1 - T/Tc) is the same as that for the non-linear reduced temperature (1 − Tc/T).

Critical conductivity exponent for Si:B

Physical Review Letters, 1991
We have determined the critical exponent which characterizes the approach of the zero-temperature conductivity to the insulating phase from measurements down to 60 mK of the resistivity of a series of just-metallic uncompensated p-type Si:B samples with dopant concentrations near the critical concentration for the metal-insulator transition.

Further Critical Exponents

2017
We discuss the existence of some further critical exponents for high dimensional percolation like the correlation-length exponents v, \({v_2}\), as well as the gap exponent \(\varDelta \). Furthermore, we consider the two-point function exponent \(\eta \) in more detail by discussing its sharp existence in Fourier space, as well as its existence in x ...

Surface Critical Exponents in Terms of Bulk Exponents

Physical Review Letters, 1977
The surface exponents associated with critical phenomena in semi-infinite systems are derived exactly in terms of bulk exponents. Results are ${\ensuremath{\gamma}}_{1,1}=\ensuremath{\nu}\ensuremath{-}1$, ${\ensuremath{\gamma}}_{1}=\ensuremath{\nu}+\frac{(\ensuremath{\gamma}\ensuremath{-}1)}{2}$, ${\ensuremath{\beta}}_{1}=\frac{(3\ensuremath ...

Inequalities for critical exponents

1992
The principal goal of the theory of critical phenomena is to make quantitative predictions for universal features of critical behavior — critical exponents, universal ratios of critical amplitudes, equations of state, and so forth — as discussed in Section 1.1. (Non-universal features, such as critical temperatures, are of lesser interest.) The present
