Using strong-coupling quantum field theory we calculate highly accurate critical exponents nu, eta from new seven-loop expansions in three dimensions. Our theoretical value for the critical exponent alpha of the specific heat near the lambda-point of superfluid helium is alpha =-0.01294+-0.00060, in excellent agreement with the space shuttle experimental value alpha =-0.01285+-0.00038. 
Six-loop renormalization group functions of O(n)-symmetric phi6-theory and epsilon-expansions of tricritical exponents up to epsilon3
We present a six-loop calculation for Wilson's β-function and for the crossover exponent of the tricritical O(n) symmetric 6 theory in d = 3 − dimensions. The counterterms of all but one of the 29
Critical properties of the N-color london model.
TLDR
The critical properties of the N-color London model are studied in d=2+1 dimensions, and it is concluded that one anomaly corresponds to an inverted 3Dxy fixed point, while the other corresponds to a 3DXY fixed point.

TLDR
From only three-loop perturbation expansions in 4-epsilon dimensions, analytic results for the exponents are obtained, which are close to those derived recently from ordinary field-theoretic variational perturbational theory to seventh order.
Fast-convergent resummation algorithm and critical exponents of φ4-theory in three dimensions
We develop an efficient algorithm for evaluating divergent perturbation expansions of field theories in the bare coupling constant gB for which we possess a finite number L of expansion coefficients
Power law singularities inn-vector models
Power law singularities and critical exponents in n-vector models are considered within a theoretical approach called GFD (grouping of Feynman diagrams) theory. It is discussed how possible values of
Field- and temperature-induced topological phase transitions in the three-dimensional N-component London superconductor
The phase diagram and critical properties of the N-component London superconductor are studied both analytically and through large-scale Monte Carlo simulations in d=2+1 dimensions (components here
Critical thermodynamics of three-dimensional MN-component field model with cubic anisotropy from higher-loop ε expansion
The critical thermodynamics of an MN-component field model with cubic anisotropy relevant to the phase transitions in certain crystals with complicated ordering is studied within the four-loop e
Dependence of variational perturbation expansions on strong-coupling behavior: Inapplicability of d expansion to field theory
We show that in applications of variational theory to quantum field theory it is essential to account for the correct Wegner exponent omega governing the approach to the strong-coupling, or scaling
Nonlinear susceptibilities of a weakly disordered uniaxial ferromagnet in the critical region
For a weakly disordered three-dimensional Ising model in the critical region, the sixth-order effective coupling constant and the fourth-and sixth-order nonlinear susceptibilities are determined. The
