Leading all-loop quantum contribution to the effective potential in general scalar field theory

Journal of High Energy Physics, 2023
The RG equation for the effective potential in the leading log (LL) approximation is constructed which is valid for an arbitrary scalar field theory in 4 dimensions.

The analytic renormalization group

Nuclear Physics B, 2016
Finite temperature Euclidean two-point functions in quantum mechanics or quantum field theory are characterized by a discrete set of Fourier coefficients Gk, k∈Z, associated with the Matsubara frequencies νk=2πk/β.

The Twin Origins of Renormalization Group Concepts [PDF]

, 2021
This paper traces the origin of renormalization group concepts back to two strands of 1950s high energy physics: the causal perturbation theory programme, which gave rise to the Stueckelberg-Petermann renormalization group, and the debate about the ...

Numerical simulations of the random phase sine-Gordon model and renormalization group predictions [PDF]

, 2007
Numerical simulations of the random phase sine-Gordon model suffer from strong finite size effects preventing the non-Gaussian log2 r component of the spatial correlator from following the universal infinite volume prediction.

Bounds on the unstable eigenvalue for the asymmetric renormalization operator for period doubling [PDF]

, 2004
We establish rigorous bounds for the unstable eigenvalue of the period-doubling renormalization operator for asymmetric unimodal maps. Herglotz-function techniques and cone invariance ideas are used.

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.

Chaotic renormalization-group trajectories [PDF]

, 1991
Under certain conditions, the renormalization-group flow of models in statistical mechanics can change dramatically under just very small changes of given external parameters.

Covariant Holographic Renormalization of Non-Conformal Field Theories [PDF]

, 2010
We present a Covariant Holographic Renormalization (CHR) procedure of fake supergravity (sugra) systems. Holography is a strong/weak coupling duality between gravitational and gauge theories, and fake sugra is a theory of gravity coupled to scalars in ...

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 ...
