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.

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 ...

Renormalized entanglement entropy and curvature invariants [PDF]
J. High Energ. Phys. 2020, 50 (2020), 2020 Renormalized entanglement entropy can be defined using the replica trick for any choice of renormalization scheme; renormalized entanglement entropy in holographic settings is expressed in terms of renormalized areas of extremal surfaces. In this paper we show how holographic renormalized entanglement entropy can be expressed in terms of the Euler ...

Renormalization of Galilean electrodynamics [PDF]
Journal of High Energy Physics, 2020 AbstractWe study the quantum properties of a Galilean-invariant abelian gauge theory coupled to a Schrödinger scalar in 2+1 dimensions. At the classical level, the theory with minimal coupling is obtained from a null-reduction of relativistic Maxwell theory coupled to a complex scalar field in 3+1 dimensions and is closely related to the Galilean ...

Exact Renormalization Groups As a Form of Entropic Dynamics
Entropy, 2018 The Renormalization Group (RG) is a set of methods that have been instrumental in tackling problems involving an infinite number of degrees of freedom, such as, for example, in quantum field theory and critical phenomena.

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.

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.

Differential Renormalization, the Action Principle and Renormalization Group Calculations [PDF]
Z.Phys. C67 (1995) 531-541, 1994 General prescriptions of differential renormalization are presented. It is shown that renormalization group functions are straightforwardly expressed through some constants that naturally arise within this approach. The status of the action principle in the framework of differential renormalization is discussed.
