New approach to Borel summation of divergent series and critical exponent estimates for an N-vector cubic model in three dimensions from five-loop ǫ expansions
Recently Kleinert and Schulte-Frohlinde calculated renormalization group (RG) functions for the cubic model in (4− ǫ)-dimensions within the five-loop approximation of the renormalized perturbation theory [1]. The critical (marginal) dimensionality Nc of the order parameter field found on the base of those expansions turned out to be smaller then three in three dimensions. This means that the cr...
متن کاملCritical exponents from five-loop strong-coupling φ4-theory in 4 − ε dimensions
Recently, one of us [1, 2] has developed a new approach to critical exponents of field theories based on the strong-coupling limit of variational perturbation expansions [3] and [4]3. This limit is relevant for critical phenomena if the renormalization constants are expressed in terms of the unrenormalized coupling constant. The theory was first applied successfully to O(N)symmetric φ4-theories...
متن کاملA Modified Borel Summation Technique
We compare and contrast three different perturbative expansions for the quartic anharmonic oscillator wavefunction and apply a modified Borel summation technique to determine the energy eigenvalues. In the first two expansions this provides the energy eigenvalues directly however in the third method we tune the wavefunctions to achieve the correct large x behaviour as first illustrated in [1]. ...
متن کاملPade Approximants and Borel Summation for QCD Perturbation Expansions
We study the applicability of Pade Approximants (PA) to estimate a ”sum” of asymptotic series of the type appearing in QCD. We indicate that one should not expect PA to converge for positive values of the coupling constant and propose to use PA for the Borel transform of the series. If the latter has poles on the positive semiaxis, the Borel integral does not exist, but we point out that the Ca...
متن کامل20 Critical Exponents from Other Expansions 20.1 Sixth-order Expansions in Three Dimensions
It is useful to compare the results obtained so far with other approaches to the critical exponents. One is a similar field-theoretic approach based on perturbation expansions of φ 4-theories. But instead of working in D = 4−ε dimensions and continuing the results to ε = 1 to obtain critical exponents in the physical dimension D = 3, perturbation expansions can be derived directly in three dime...
