Renormalization of Discrete Models without Background [PDF]
, 2002 Conventional renormalization methods in statistical physics and lattice quantum field theory assume a flat metric background. We outline here a generalization of such methods to models on discretized spaces without metric background.

Ultrafast Anisotropic Optical‐Gap Shift in Low‐Symmetry Layered GeS
Advanced Optical Materials, EarlyView.This study reveals ultrafast, anisotropic optical‐gap shift dynamics in GeS. Optical excitation induces a significant redshift in the polarization along the zigzag direction, about three times greater than that along the perpendicular armchair direction.

Nonperturbative Renormalization of Nonlocal Quark Bilinears for Parton Quasidistribution Functions on the Lattice Using an Auxiliary Field. [PDF]
Physical Review Letters, 2017 Parton quasidistribution functions provide a path toward an ab initio calculation of parton distribution functions (PDFs) using lattice QCD. One of the problems faced in calculations of quasi-PDFs is the renormalization of a nonlocal operator.

Maximal abelian and Curci-Ferrari gauges in momentum subtraction at three loops
, 2015 The vertex structure of QCD fixed in the maximal abelian gauge (MAG) and Curci-Ferrari gauge is analysed at two loops at the fully symmetric point for the 3-point functions corresponding to the three momentum subtraction (MOM) renormalization schemes ...

The three loop on-shell renormalization of QCD and QED [PDF]
, 2000 We describe a calculation of the on-shell renormalization factors in QCD and QED at the three loop level. Explicit results for the fermion mass renormalization factor Zm and the on-shell fermion wave function renormalization constant Z2 are given.

Renormalization as a functor on bialgebras
Journal of Pure and Applied Algebra, 2007 The Hopf algebra of renormalization in quantum field theory is described at a general level. The products of fields at a point are assumed to form a bialgebra B and renormalization endows T(T(B)^+), the double tensor algebra of B, with the structure of a noncommutative bialgebra. When the bialgebra B is commutative, renormalization turns S(S(B)^+), the

Acoustic Rayleigh Wave Turbulence in Soft Viscoelastic Matter
Advanced Science, EarlyView.Discrete acoustic Rayleigh wave turbulence (DARWT) is observed on the free surface of viscoelastic materials under monochromatic excitation. Governed by bulk shear rigidity supporting inertial modes against surface tension, the nonlinear Rayleigh waves exhibit distinct power‐law scaling and turbulence features in their Kolmogorov–Zakharov spectra. This

Renormalizing Curvature Integrals on Poincare-Einstein Manifolds [PDF]
Advances in Mathematics, Volume 221, Issue 1, 1 May 2009, Pages
140-169, 2005 After analyzing renormalization schemes on a Poincar\'e-Einstein manifold, we study the renormalized integrals of scalar Riemannian invariants. The behavior of the renormalized volume is well-known, and we show any scalar Riemannian invariant renormalizes similarly. We consider characteristic forms and their behavior under a variation of the Poincar\'e-

Local renormalization method for random systems
, 2009 In this paper, we introduce a real-space renormalization transformation for random spin systems on 2D lattices. The general method is formulated for random systems and results from merging two well known real space renormalization techniques, namely the ...
