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.

Solutions for Fractional Schrödinger Equation Involving Critical Exponent via Local Pohozaev Identities

Advanced Nonlinear Studies, 2019
We consider the following fractional Schrödinger equation involving critical exponent: { ( - Δ ) s ⁢ u + V ⁢ ( y ) ⁢ u = u 2 s * - 1 in ⁢ ℝ N , u > 0 , y ∈ ℝ N , \left\{\begin{aligned} &\displaystyle(-\Delta)^{s}u+V(y)u=u^{2^{*}_{s}-1}&&% \displaystyle ...

Critical exponent of infinite balanced words via the Pell number system

Words, 2019
In a recent paper of Rampersad et al., the authors conjectured that the smallest possible critical exponent of an infinite balanced word over a 5-letter alphabet is $3/2$.

Logarithmic improvements in $$L^{p}$$Lp bounds for eigenfunctions at the critical exponent in the presence of nonpositive curvature

Inventiones Mathematicae, 2017
We consider the problem of proving $$L^p$$Lp bounds for eigenfunctions of the Laplacian in the high frequency limit in the presence of nonpositive curvature and more generally, manifolds without conjugate points. In particular, we prove estimates at the “

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 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 ...

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.
