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.

Non-perturbative renormalization for a renormalization group improved gauge action [PDF]
, 2001 Renormalization constants of vector ($Z_V$) and axial-vector ($Z_A$) currents are determined non-perturbatively in quenched QCD for a renormalization group improved gauge action and a tadpole improved clover quark action using the Schr\"odinger ...

Advanced Science, EarlyView.Inhalable eugenol (EUG) from clove oil attenuates NAFLD by activating hepatic olfactory receptor Olfr544, triggering cAMP/PKA/CREB signaling to enhance lipolysis/oxidation. EUG concurrently restores gut microbiota, enriching probiotics (L. reuteri XR23/L. johnsonii XR25) and metabolites (IPA/5‐HIAA) that suppress lipogenesis.

Effective action for the Yukawa model in curved spacetime
Journal of High Energy Physics, 2018 We consider the one-loop renormalization of a real scalar field interacting with a Dirac spinor field in curved spacetime. A general Yukawa interaction is considered which includes both a scalar and a pseudoscalar coupling. The scalar field is assumed to

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 ...

Advanced Electronic Materials, EarlyView.Vacuum thermal evaporation (VTE) is the dominant method for manufacturing high‐performance small‐molecule organic light‐emitting diodes (OLEDs). Its mature application in OLEDs offers valuable guidance for emerging perovskite light‐emitting diodes (PeLEDs).

A note on defect stability in d = 4 − ε
Journal of High Energy PhysicsWe explore the space of scalar line, surface and interface defect field theories in d = 4 − ε by examining their stability properties under generic deformations.

Advanced Energy Materials, EarlyView.Exciton diffusion length in organic semiconductor films is determined from encounter/annihilation rates. Non‐normalized exciton densities and proper intrinsic lifetime reference avoid over‐parametrization of the fits. Monte Carlo Simulation of individual molecule‐to‐molecule hops reproduce these results (②) when matching lattice constant and hoping ...

Renormalization group analysis for thermal turbulence
International Journal of Mathematics and Mathematical Sciences, 1997 Renormalization group theory is applied to thermal turbulence. Turbulent fluxes for the flow are accounted for by repeatedly recasting the governing equations with the smallest scales represented by effective larger scales.

Cluster functional renormalization group [PDF]
Physical Review B, 2014 Functional renormalization group (FRG) has become a diverse and powerful tool to derive effective low-energy scattering vertices of interacting many-body systems. Starting from a non-interacting expansion point of the action, the flow of the RG parameter Lambda allows to trace the evolution of the effective one-particle and two-particle vertices ...
