Quantization of nonequilibrium heat transport models based on isomorphism and gauge symmetry [PDF]

open access: yesScientific Reports
The diffusive model in a local thermal equilibrium medium has been well established for classical heat transport. In this study, we investigated the gauge potential formulation of a heat transfer model in a non equilibrium system within classical and ...

Time reversal and reciprocity

open access: yesAAPPS Bulletin, 2022
In this paper, we review and discuss the main properties of the time-reversal operator T and its action in classical electromagnetism and in quantum mechanics.

A tale of analogies: a review on gravitomagnetic effects, rotating sources, observers and all that

open access: yesJournal of Physics Communications, 2023
Gravitoelectromagnetic analogies are somewhat ubiquitous in General Relativity, and they are often used to explain peculiar effects of Einstein’s theory of gravity in terms of familiar results from classical electromagnetism.

Current-induced magnetization caused by crystal chirality in nonmagnetic elemental tellurium

open access: yesPhysical Review Research, 2021
Chiral matter has a structure that lacks inversion, mirror, and rotoreflection symmetry; thus, a given chiral material has either a right- or left-handed structure. In chiral matter, electricity and magnetism can be coupled in an exotic manner beyond the

Classical limit of higher-spin string amplitudes

open access: yesJournal of High Energy Physics, 2023
It has been shown that a special set of three-point amplitudes between two massive spinning states and a graviton reproduces the linearised stress-energy tensor for a Kerr black hole in the classical limit. In this work we revisit this result and compare

Spinning gauged boson and Dirac stars: A comparative study

open access: yesPhysics Letters B, 2022
Scalar boson stars and Dirac stars are solitonic solutions of the Einstein–Klein-Gordon and Einstein-Dirac classical equations, respectively. Despite the different bosonic vs.

On the Classical Coupling between Gravity and Electromagnetism

open access: yesAtoms, 2015
Coupling between electromagnetism and gravity, manifested as the distorted Coulomb field of a charge distribution in a gravitational field, has never been observed.

Electromagnetism in terms of quantum measurements [PDF]

open access: yes, 2015
We consider the question whether electromagnetism can be derived from quantum physics of measurements. It turns out that this is possible, both for quantum and classical electromagnetism, if we use more recent innovations such as smearing of observables ...

Spin supplementary condition in quantum field theory: covariant SSC and physical state projection

open access: yesJournal of High Energy Physics, 2023
The spin supplementary conditions are constraints on spin degrees of freedom in classical relativity which restricts physical degrees of freedom to rotations.
