Renormalization scheme dependence and renormalization group summation [PDF]
Canadian Journal of Physics, 2018 We consider logarithmic contributions to the free energy, instanton effective action, and Laplace sum rules in QCD that are a consequence of radiative corrections. Upon summing these contributions by using the renormalization group, all dependence on the renormalization scale parameter μ cancels.

Towards general scalar-Yukawa renormalisation group equations at three-loop order
Journal of High Energy Physics, 2021 For arbitrary four-dimensional quantum field theories with scalars and fermions, renormalisation group equations in the MS ¯ $$ \overline{\mathrm{MS}} $$ scheme are investigated at three-loop order in perturbation theory.

Renormalization Group in Non-Relativistic Quantum Statistics [PDF]
EPJ Web of Conferences, 2020 Dynamic behaviour of a boson gas near the condensation transition in the symmetric phase is analyzed with the use of an effective large-scale model derived from time-dependent Green functions at finite temperature.

Renormalization Group in Potential Scattering [PDF]
Physical Review Letters, 1995 Renormalization group equations for the physical t matrix are written for quantum scattering with some potentials singular at the origin in two and three dimensions. The momentum-space perturbative treatment of these scattering problems exhibits ultraviolet divergences and permits renormalization leading to a scale.

Renormalization Group and divergences [PDF]
Journal of Statistical Physics, 2014 Application of asymptotic freedom to the ultraviolet stability in Euclidean quantum field theories is revisited and illustrated through the hierarchical model making also use of a few technical developments that followed the original works of Wilson on the renormalization group.

Renormalization group approach to spontaneous stochasticity
Physical Review Research, 2020 We develop a theoretical approach to “spontaneous stochasticity” in classical dynamical systems that are nearly singular and weakly perturbed by noise. This phenomenon is associated with a breakdown in the uniqueness of solutions for fixed initial data ...

Critical phenomena and functional renormalization group
He jishu, 2023 Recent progress in studies on quantum chromodynamics (QCD) phase transition and related critical phenomena within the functional renormalization group (fRG) approach were reviewed, including the nonperturbative critical exponents and baryon number ...

Renormalization group theory of earthquakes [PDF]
Nonlinear Processes in Geophysics, 1996 We study theoretically the physical origin of the proposed discrete scale invariance of earthquake processes, at the origin of the universal log-periodic corrections to scaling, recently discovered in regional seismic activity ...
