- Estimates of Critical Quantities from an Expansion in Mass: Ising Model on the Simple Cubic Lattice Hirofumi Yamada Física, Astronomía y Matemáticas Delta expansion Ising model Expansion in mass Critical quantities In the Ising model on the simple cubic lattice, we describe the inverse temperature β and other quantities relevant for the computation of critical quantities in terms of a dimensionless squared mass M . The critical behaviors of those quantities are represented by the linear differen- tial equations with constant coefficients which are related to critical exponents. We estimate the critical temperature and exponents via an expansion in the inverse powers of the mass under the use of δ -expansion. The critical inverse tem- perature β c is estimated first in unbiased manner and then critical exponents are also estimated in biased and unbiased self-contained way including ω , the correction-to-scaling exponent, ν , η ,and γ . 2015 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46442560003 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.6 Vol.45
