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 ...

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 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.

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 ...

Critical viscosity exponent for classical fluids

Physical Review E, 2005
A self-consistent mode-coupling calculation of the critical viscosity exponent z(eta) for classical fluids is performed by including the memory effect and the vertex corrections. The incorporation of the memory effect is through a self-consistency procedure that evaluates the order parameter and shear momentum relaxation rates at nonzero frequencies ...

A Dirichlet problem involving critical exponents

Nonlinear Analysis: Theory, Methods & Applications, 1995
The goal of this work is to find a nontrivial solution of the equation: \[ - \Delta_p (u) \equiv - \text{div} \bigl( |Du |^{p - 2} Du \bigr) = |u |^{r - 2} u + \lambda g(u), \quad u > 0 \text{ in } \Omega, \quad u = 0 \text{ on } \partial \Omega, \tag{1} \] where \(\Omega\) is a bounded and smooth domain of \(\mathbb{R}^N\).

Critical exponents in four-fermion theories

Physical Review D, 1994
We find the complete set of critical exponents for the simplest four-fermion theory in all dimensions $2ld\ensuremath{\le}4$. They satisfy the hyperscaling relations.

Probe independence of hyperfine critical exponents

Physical Review B, 1976
The critical exponent $\ensuremath{\beta}$ for magnetically ordered materials has been obtained from a variety of hyperfine experiments, such as nuclear magnetic resonance, perturbed angular correlations, and M\"ossbauer effect. In this paper we discuss probe disturbance effects on hyperfine measurements of $\ensuremath{\beta}$.
