Power laws in physics [PDF]

open access: yesNature Reviews Physics, 4, 501-503 (2022), 2022
Getting the most from power-law-type data can be challenging. James Sethna points out some of the pitfalls in studying power laws arising from emergent scale invariance, as well as important opportunities.

Physics of the Power Corrections in QCD [PDF]

open access: yesSurveys in High Energy Physics, 1999
We review the physics of the power corrections to the parton model. In the first part, we consider the power corrections which characterize the infrared sensitivity of Feynman graphs when the contribution of short distances dominates.

The physics of electric power systems [PDF]

open access: yesEPJ Web of Conferences, 2013
The article describes electric power systems from a physicist’s point of view. In contrast to common introductory textbooks on power systems, the emphasis is on the physical design, that is the material selection and the choice of the geometrical shape ...

The physics of power systems operation [PDF]

open access: yesEPJ Web of Conferences, 2015
The article explains the operation of power systems from the point of view of physics. Physicists imagine things, rather than in terms of impedances and circuits, in terms of fields and energy conversions. The account is concrete and simple.

GaN-based power devices: Physics, reliability, and perspectives [PDF]

open access: yesJournal of Applied Physics, 2021
Over the last decade, gallium nitride (GaN) has emerged as an excellent material for the fabrication of power devices. Among the semiconductors for which power devices are already available in the market, GaN has the widest energy gap, the largest critical field, and the highest saturation velocity, thus representing an excellent material for the ...

Physics and nuclear power [PDF]

open access: goldJournal of Physics: Conference Series, 2008
Nuclear power owes its origin to physicists. Fission was demonstrated by physicists and chemists and the first nuclear reactor project was led by physicists. However as nuclear power was harnessed to produce electricity the role of the engineer became stronger.

Physics Without Physics: The Power of Information-theoretical Principles [PDF]

open access: yesInternational Journal of Theoretical Physics, 2016
David Finkelstein was very fond of the new information-theoretic paradigm of physics advocated by John Archibald Wheeler and Richard Feynman. Only recently, however, the paradigm has concretely shown its full power, with the derivation of quantum theory (

Features of heavy physics in the CMB power spectrum [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2010
The computation of the primordial power spectrum in multi-field inflation models requires us to correctly account for all relevant interactions between adiabatic and non-adiabatic modes around and after horizon crossing.

Physics-Informed Neural Networks for Power Systems [PDF]

open access: greenIEEE Power & Energy Society General Meeting, 2019
This paper introduces for the first time, to our knowledge, a framework for physics-informed neural networks in power system applications. Exploiting the underlying physical laws governing power systems, and inspired by recent developments in the field ...
