Axion‐Like Interactions and CFT in Topological Matter, Anomaly Sum Rules and the Faraday Effect
Advanced Physics Research, EarlyView.This review investigates the connection between chiral anomalies and their manifestation in topological materials, using both perturbative methods based on ordinary quantum field theory and conformal field theory (CFT). It emphasizes the role of CFT in momentum space for parity‐odd correlation functions, and their reconstruction by the inclusion of a ...

Kinematically dependent renormalization
Physics Letters B, 2018 We suggest a renewed view on non-renormalizable interactions treated perturbatively within a kinematically dependent renormalization procedure. It is based on the usual BPHZ R-operation which is equally applicable to any local QFT independently whether it is renormalizable or not.

A Field Guide to Non‐Onsager Quantum Oscillations in Metals
Advanced Physics Research, EarlyView.The observation of quantum oscillations is usually taken as strong evidence for the existence of a Fermi surface according to the famous Onsager relation. The article reviews mechanisms that generate quantum oscillation frequencies that defy the Onsager relation where special emphasis is put on the recently discovered quasi‐particle lifetime ...

RENORMALIZATION WITHOUT INFINITIES [PDF]
International Journal of Modern Physics A, 2005 Most renormalizable quantum field theories can be rephrased in terms of Feynman diagrams that only contain dressed irreducible 2-, 3-, and 4-point vertices. These irreducible vertices in turn can be solved from equations that also only contain dressed irreducible vertices. The diagrams and equations that one ends up with do not contain any ultraviolet

Unveiling Electron‐Phonon and Electron‐Magnon Interactions in the Weak Itinerant Ferromagnet LaCo2P2
Advanced Physics Research, EarlyView.Electron‐boson interactions in the weak itinerant ferromagnet LaCo2P2 are investigated, addressing both surface and bulk properties. The intricate renormalization of electronic states due to electron‐phonon and electron‐magnon interactions is examined, highlighting their distinct impacts on the electronic structure.

Applications of non-perturbative renormalization [PDF]
arXiv, 2000 A short survey of the renormalization problem in QCD and its non-perturbative solution by means of numerical simulations on the lattice is given. Most emphasis is on scale dependent renormalizations, which can be reliably addressed via a recursive finite-size scaling procedure employing a suitable intermediate renormalization scheme.

Three‐dimensional lattice ground states for Riesz and Lennard‐Jones–type energies
Studies in Applied Mathematics, Volume 150, Issue 1, Page 69-91, January 2023., 2023 Abstract The Riesz potential fs(r)=r−s$f_s(r)=r^{-s}$ is known to be an important building block of many interactions, including Lennard‐Jones–type potentials fn,mLJ(r):=ar−n−br−m$f_{n,m}^{\rm {LJ}}(r):=a r^{-n}-b r^{-m}$, n>m$n>m$ that are widely used in molecular simulations.

The Slow‐Rotating Nucleus of Comet C/2013 R1 (Lovejoy)
Astronomische Nachrichten, EarlyView.ABSTRACT The close approach of comet C/2013 R1 (Lovejoy) allowed us to conduct an in‐depth study of the morphology of the inner coma. From the measurement of the dust emission structures expanding near the cometary nucleus in November–December 2013, we derived a slow rotation period of 47.8±1.2$$ 47.8\pm 1.2 $$ h.
