On the Critical Exponents for the Λ-Transition in Liquid Helium

Abstract

The use of a new method for summing divergent series makes it possible to significantly increase the accuracy of determining the critical exponents from the field theoretical renormalization group. The exponent value ν=0.6700\pm 0.0006 for the λ-transition in liquid helium is in good agreement with the experiment, but contradicts the last theoretical results based on using high-temperature series, the Monte Carlo method, and their synthesis.
