An isolated classical chaotic system, when driven by the slow change in several parameters, responds with two reaction forces: geometric friction and geometric magnetism. By using the theory of quantum fluctuation relations, we show that this holds true also for open quantum systems and provide explicit expressions for those forces in this case. This extends the concept of Berry curvature to th...

When electrons are driven through unconventional magnetic structures, such as skyrmions, they experience emergent electromagnetic fields that originate several Hall effects. Independently, ground-state emergent magnetic fields can also lead to orbital magnetism, even without the spin-orbit interaction. The close parallel between the geometric theories of the Hall effects and of the orbital magn...

Multiferroics are materials that simultaneously exhibit more than one ferroic order parameters, such as ferroelectricity, ferroelasticity and ferromagnetism. Recently, multiferroicity has received a significant revival of interest due to the colossal magnetoelectric coupling effect for the development of nano-ferronics. In this mini-review, we focus on a recent study of ferroelectricity, magnet...

The present article analyzes aspects of the intellectual trajectory of Maria Cecília Ferro Donnangelo and her principal works. The text emphasizes the innovating and pioneer role her work played in the first moments of social sciences in the field of health in the mid sixties, occurring just together with changes in medical education and medical practice in Brazil.

In a double-blind trial the response to treatment with Ferro-Gradume (a slow-release preparation of ferrous sulphate) has been compared in the same individuals with the response to ferrous fumarate in a single daily dose regimen using a similar dose of iron. No significant difference was found in the therapeutic response or in the incidence of side-effects between the two preparations.
