Revisiting (logarithmic) scaling relations using renormalization group
We explicitly compute the critical exponents associated with logarithmic corrections (the so-called hatted exponents) starting from the renormalization group equations and the mean field behavior for a wide class of models at the upper critical behavior (for short and long range φ n -theories) an...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | We explicitly compute the critical exponents associated with logarithmic corrections (the so-called hatted exponents) starting from the renormalization group equations and the mean field behavior for a wide class of models
at the upper critical behavior (for short and long range φ
n
-theories) and below it. This allows us to check the
scaling relations among these critical exponents obtained by analysing the complex singularities (Lee-Yang and
Fisher zeroes) of these models. Moreover, we have obtained an explicit method to compute the ϙˆ exponent
[defined by ξ ∼ L(logL)
ϙˆ
] and, finally, we have found a new derivation of the scaling law associated with it. |
