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

Physical 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

Journal 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

Physics 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

Atoms, 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]

, 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

Journal 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.

The classical geometrization of the electromagnetism [PDF]

International Journal of Geometric Methods in Modern Physics, 2015
Following the line of the history, if by one side the electromagnetic theory was consolidated on the 19th century, the emergence of the special and the general relativity theories on the 20th century opened possibilities of further developments, with the search for the unification of the gravitation and the electromagnetism on a single unified theory.

On the electrodynamics of moving bodies at low velocities [PDF]

, 2005
We discuss the seminal article in which Le Bellac and Levy-Leblond have identified two Galilean limits of electromagnetism, and its modern implications.

Time Reversal in Classical Electromagnetism [PDF]

The British Journal for the Philosophy of Science, 2009
Richard Feynman has claimed that anti-particles are nothing but particles ‘propagating backwards in time’; that time reversing a particle state always turns it into the corresponding anti-particle state. According to standard quantum eld theory textbooks this is not so: time reversal does not turn particles into anti-particles.

Semi-Active Magnetic Levitation System for Education

Applied Sciences, 2021
This paper describes how to construct a low-cost magnetic levitation system (MagLev). The MagLev has been intensively used in engineering education, allowing instructors and students to learn through hands-on experiences of essential concepts, such as ...
