Gravitational Dressing of Renormalization Group [PDF]

Physical Review Letters, 1993
We study the gravitational dressing of renormalizable two-dimensional field theories. Our main result is that the one-loop $\beta$-function is finitely renormalized by the factor ${k+2\over k+1}$, where $k$ is the central charge of the gravitational $SL ...

Renormalization group theory of molecular dynamics [PDF]

Scientific Reports, 2021
Large scale computation by molecular dynamics (MD) method is often challenging or even impractical due to its computational cost, in spite of its wide applications in a variety of fields.

Wilsonian renormalization group versus subtractive renormalization in effective field theories for nucleon–nucleon scattering

Nuclear Physics B, 2017
We compare the subtractive renormalization and the Wilsonian renormalization group approaches in the context of an effective field theory for the two-nucleon system. Based on an exactly solvable model of contact interactions, we observe that the standard

Numerical Renormalization Group at Criticality [PDF]

, 1996
We apply a recently developed numerical renormalization group, the corner-transfer-matrix renormalization group (CTMRG), to 2D classical lattice models at their critical temperatures.

Interpolation Formulas for Asymptotically Safe Cosmology

Universe, 2023
Simple interpolation formulas are proposed for the description of the renormalization group (RG) scale dependences of the gravitational couplings in the framework of the 2-parameters Einstein-Hilbert (EH) theory of gravity and applied to a simple ...

Multi-collinear splitting kernels for track function evolution

Journal of High Energy Physics, 2023
Jets and their substructure play a central role in many analyses at the Large Hadron Collider (LHC). To improve the precision of measurements, as well as to enable measurement of jet substructure at increasingly small angular scales, tracking information

Triad second renormalization group

Journal of High Energy Physics, 2022
We propose a second renormalization group (SRG) in the triad representation of tensor networks. The SRG method improves two parts of the triad tensor renormalization group, which are the decomposition of intermediate tensors and the preparation of ...

Renormalization group evolution with scalar leptoquarks

Journal of High Energy Physics, 2023
Leptoquarks are theoretically well-motivated and have received increasing attention in recent years as they can explain several hints for physics beyond the Standard Model.

Higher logarithms and ε-poles for the MS-like renormalization prescriptions

Journal of High Energy Physics, 2023
We consider a version of dimensional regularization (reduction) in which the dimensionful regularization parameter Λ is in general different from the renormalization scale μ.

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.
