Renormalization and non-renormalization of scalar EFTs at higher orders [PDF]
Journal of High Energy Physics, 2021 Abstract We renormalize massless scalar effective field theories (EFTs) to higher loop orders and higher orders in the EFT expansion. To facilitate EFT calculations with the R* renormalization method, we construct suitable operator bases using Hilbert series and related ideas in commutative algebra and conformal representation ...

A non-perturbative real-space renormalization group scheme for the spin-1/2 XXX Heisenberg model [PDF]
Phys. Rev. B 64, 174408 (2001), 1999 In this article we apply a recently invented analytical real-space renormalization group formulation which is based on numerical concepts of the density matrix renormalization group. Within a rigorous mathematical framework we construct non-perturbative renormalization group transformations for the spin-1/2 XXX Heisenberg model in the finite ...

Bosonization and Functional Renormalization Group Approach in the Framework of QED_2 [PDF]
, 2011 Known results on two-dimensional quantum electrodynamics (QED_2) have been used to study the dependence of functional renormalization group equations on renormalization schemes and approximations applied for its bosonized version. It is demonstrated that

Renormalization scheme dependence and renormalization group summation [PDF]
Canadian Journal of Physics, 2018 We consider logarithmic contributions to the free energy, instanton effective action, and Laplace sum rules in QCD that are a consequence of radiative corrections. Upon summing these contributions by using the renormalization group, all dependence on the renormalization scale parameter μ cancels.

Energetics of Sulfur‐Carbon Interaction
ChemPhysChem, Volume 23, Issue 24, December 16, 2022., 2022 Immersion microcalorimetry is used to evaluate the sulfur‐carbon interaction. Irrespective of their porosity, the carbons lead to similar immersion enthalpies per unit area for liquid sulfur. This means they have similar surface‐liquid interactions and that liquid sulfur below the polymerization temperature, wets the whole surface accessible to ...

Entropy and Its Discontents: A Note on Definitions
Entropy, 2014 The routine definitions of Shannon entropy for both discrete and continuous probability laws show inconsistencies that make them not reciprocally coherent.

Matrix product operators, matrix product states, and ab initio density matrix renormalization group algorithms. [PDF]
Journal of Chemical Physics, 2016 Current descriptions of the ab initio density matrix renormalization group (DMRG) algorithm use two superficially different languages: an older language of the renormalization group and renormalized operators, and a more recent language of matrix product
