A Generic Renormalization Method in Curved Spaces and at Finite Temperature [PDF]
Int.J.Mod.Phys. A10 (1995) 2819-2839, 1994 Based only on simple principles of renormalization in coordinate space, we derive closed renormalized amplitudes and renormalization group constants at 1- and 2-loop orders for scalar field theories in general backgrounds. This is achieved through a generic renormalization procedure we develop exploiting the central idea behind differential ...

Renormalization of 2PI resummation: a renormalization scheme approach [PDF]
Phys.Rev.D76:125004,2007, 2006 A practical method is suggested for performing renormalized 2PI resummation at finite temperature using specific momentum dependent renormalization schemes. In this method there is no need to solve Bethe-Salpeter equations for 2PI resummation. We examine the consistency of such schemes in the paper.

Non-perturbative Renormalization of Bilinear Operators with Improved Staggered Quarks [PDF]
arXiv, 2013 We present renormalization factors for the bilinear operators obtained using the non-perturbative renormalization method (NPR) in the RI-MOM scheme with improved staggered fermions on the MILC asqtad lattices ($N_f = 2+1$). We use the MILC coarse ensembles with $20^3 \times 64$ geometry and $am_{\ell}/am_s = 0.01/0.05$.

Universal Amplitude Ratios for Constrained Critical Systems [PDF]
, 2014 The critical properties of systems under constraint differ from their ideal counterparts through Fisher renormalization. The mathematical properties of Fisher renormalization applied to critical exponents are well known: the renormalized indices obey the same scaling relations as the ideal ones and the transformations are involutions in the sense that ...

Laplacian renormalization group for heterogeneous networks [PDF]
Nature Physics, 2022 The renormalization group method is routinely employed in studies of criticality in many areas of physics. A framework based on a field theoretical description of information diffusion now extends this tool to the study of complex networks.

Phonon renormalization in reconstructed MoS2 moiré superlattices [PDF]
Nature Materials, 2020 In moiré crystals formed by stacking van der Waals materials, surprisingly diverse correlated electronic phases and optical properties can be realized by a subtle change in the twist angle.

Machine Learning: Science and Technology, 2023 In this note we present a fully information theoretic approach to renormalization inspired by Bayesian statistical inference, which we refer to as Bayesian renormalization.

Reconstruction of observed mechanical motions with artificial intelligence tools
New Journal of Physics, 2022 The goal of this paper is to determine the laws of observed trajectories assuming that there is a mechanical system in the background and using these laws to continue the observed motion in a plausible way.
