A Renormalization Group Procedure for Fiber Bundle Models
Frontiers in Physics, 2018 We introduce two versions of a renormalization group scheme for the equal load sharing fiber bundle model. The renormalization group is based on formulating the fiber bundle model in the language of damage mechanics.

From Renormalization Group Flows to Cosmology
Frontiers in Physics, 2020 According to the asymptotic-safety conjecture, the gravitational renormalization group flow features an ultraviolet-attractive fixed point that makes the theory renormalizable and ultraviolet complete.

Renormalization group coefficients and the S-matrix [PDF]
Journal of High Energy Physics, 2016 We show how to use on-shell unitarity methods to calculate renormalization group coefficients such as beta functions and anomalous dimensions. The central objects are the form factors of composite operators. Their discontinuities can be calculated via phase-space integrals and are related to corresponding anomalous dimensions.

Tailoring Robust Quantum Anomalous Hall Effect via Entropy‐Engineering
Advanced Materials, EarlyView.Bandstructure renormalization, without (w/o) spin‐orbit interaction (SOI) (left) and with SOI (right), in the low‐energy Dirac bands of zero‐entropy (purple) and entropic (green) VCl3 monolayer (ML) with long‐range ordering (LRO). Abstract The development of quantum materials and the tailoring of their functional properties is of fundamental interest ...

Stochastic renormalization group and gradient flow
Journal of High Energy Physics, 2020 A non-perturbative and continuous definition of RG transformations as stochastic processes is proposed, inspired by the observation that the functional RG equations for effective Boltzmann factors may be interpreted as Fokker-Planck equations. The result

The Bogolyubov renormalization group
Russian Mathematical Surveys, 1994 We begin with personal notes describing the atmosphere of "Bogoliubov renormalization group" birth. Then we expose the history of RG discovery in the QFT and of the RG method devising in the mid-fifties. The third part is devoted to proliferation of RG ideas into diverse parts of theoretical physics.

Renormalization Group Functional Equations
, 2010 Functional conjugation methods are used to analyze the global structure of various renormalization group trajectories, and to gain insight into the interplay between continuous and discrete rescaling.

CORE and the Haldane Conjecture [PDF]
, 2000 The Contractor Renormalization group formalism (CORE) is a real-space renormalization group method which is the Hamiltonian analogue of the Wilson exact renormalization group equations.

Temperature‐Dependent Optical Properties of CsCu2I3 Perovskites
Advanced Materials Interfaces, EarlyView.This work explores the temperature‐dependent optical properties of CsCu₂I₃ nanocrystals using transmittance and photoluminescence techniques. Resonant excitation conditions and energy level modeling reveal critical insights into the self‐trapped exciton emission mechanism.

Hard-soft renormalization and the exact renormalization group [PDF]
Nuclear Physics B, 1998 The Wilsonian exact renormalization group gives a natural framework in which ultraviolet and infrared divergences can be treated separately. In massless QED we introduce, as the only mass parameter, a renormalization scale $ _R > 0$. We prove, using the flow equation technique, that infrared convergence is a necessary consequence of any zero ...
