IEEE Access, 2020 For the accurate and reliable multi-port characterization of vertical interconnection array structures, this paper presents an indirect-contact probing method to obtain network parameters of N-port device-under-tests (DUTs) using an M-port (N > M ...

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

Lecture notes on holographic renormalization [PDF]
Classical and quantum gravity, 2002 We review the formalism of holographic renormalization. We start by discussing mathematical results on asymptotically anti-de Sitter (AdS) spacetimes. We then outline the general method of holographic renormalization. The method is illustrated by working

International Journal of Modern Physics D, 2018 We propose that the consistent field renormalization of gravity requires a specific Weyl transformation of the metric tensor. As a consequence, proper length and time, as well as energy and momentum, become functions of scale. We estimate the functional form of the field renormalization factor by imposing a minimum resolvable distance scale under an ...

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.

Mutual information, neural networks and the renormalization group [PDF]
Nature Physics, 2017 Physical systems differing in their microscopic details often display strikingly similar behaviour when probed at macroscopic scales. Those universal properties, largely determining their physical characteristics, are revealed by the powerful ...

Stochastic Electrodynamics: Renormalized Noise in the Hydrogen Ground-State Problem
Frontiers in Physics, 2020 The hydrogen ground-state problem is a touchstone for the theory of Stochastic Electrodynamics. Recently, we have shown numerically and theoretically that the H-atom self-ionizes after a characteristic time.
