Specific-heat amplitude ratio for anisotropic Lifshitz critical behaviors
Specific-heat amplitude ratio for anisotropic Lifshitz critical behaviors
We determine the specific-heat amplitude ratio near a m-axial Lifshitz point and show its universal character. Using a recent renormalization group picture along with field-theoretical ${\ensuremath{\epsilon}}_{L}$-expansion techniques, we established this amplitude ratio at the one-loop order. We estimate the numerical value of this amplitude ratio for $m=1$ and $d=3.$ The …
