Renormalization group and nonequilibrium action in stochastic field theory [PDF]
, 2002 We investigate the renormalization group approach to nonequilibrium field theory. We show that it is possible to derive nontrivial renormalization group flow from iterative coarse graining of a closed-time-path action.

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 ...

Sequences of Trees and Higher-Order Renormalization Group Equations [PDF]
, 2022 We define a notion of higher order renormalization group equation and investigate when a sequence of trees satisfies such an equation. In the strongest sense, the sequence of trees satisfies a $k$th order renormalization group equation when applying any choice of Feynman rules results in a Green function satisfying a $k$th order renormalization group ...

The Holographic Renormalization Group [PDF]
Fortschritte der Physik, 2001 In this lecture, we review the derivation of the holographic renormalization group given in hep-th/9912012. Some extra background material is included, and various applications are discussed.

Renormalization Group evolution from on-shell SMEFT
Journal of High Energy Physics, 2021 We describe the on-shell method to derive the Renormalization Group (RG) evolution of Wilson coefficients of high dimensional operators at one loop, which is a necessary part in the on-shell construction of the Standard Model Effective Field Theory ...

On a realization of {β}-expansion in QCD
Journal of High Energy Physics, 2017 We suggest a simple algebraic approach to fix the elements of the {β}-expansion for renormalization group invariant quantities, which uses additional degrees of freedom.

The renormalization group and the diffusion equation [PDF]
Progress of Theoretical and Experimental Physics, 2020 Abstract We study the relationship between the renormalization group and the diffusion equation. We consider the exact renormalization group equation for a scalar field that includes an arbitrary cutoff function and an arbitrary quadratic seed action.

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 ...

EXACT RENORMALIZATION GROUP FOR POINT INTERACTIONS
Acta Polytechnica, 2014 Renormalization is one of the deepest ideas in physics, yet its exact implementation in any interesting problem is usually very hard. In the present work, following the approach by Glazek and Maslowski in the flat space, we will study the exact ...

Ambipolar‐To‐Unipolar Conversion in Ultrathin 2D Semiconductors
Small Structures, Volume 3, Issue 12, December 2022., 2022 The applications of many 2D semiconductors have attracted considerable attention, but are severely limited by their ambipolar characteristics, which has sparked controversy about rethinking their potential. Thus, a comprehensive review is necessary for in‐depth understanding and to propose the optimum solutions for ambipolar treatment. Furthermore, the
