Nonlinear optical diode effect in a magnetic Weyl semimetal.

Diode effects are of great interest for both fundamental physics and modern technologies. Electrical diode effects (nonreciprocal transport) have been observed in Weyl systems. Optical diode effects arising from the Weyl fermions have been theoretically considered but not probed experimentally.

Quantum metric nonlinear Hall effect in a topological antiferromagnetic heterostructure.

Quantum geometry in condensed-matter physics has two components: the real part quantum metric and the imaginary part Berry curvature. Whereas the effects of Berry curvature have been observed through phenomena such as the quantum Hall effect in two-dimensional electron gases and the anomalous Hall effect (AHE) in ferromagnets, the quantum metric has rarely been explored. Here, we report a nonlinear Hall effect induced by the quantum metric dipole by interfacing even-layered MnBiTe with black phosphorus.

Produce a French-Canadian translation of AMSTAR 2, affirm its content validity, and examine interrater reliability. Based on Vallerand's methodological approach, we conducted forward and parallel inverse-translations. Subsequently, an expert panel evaluated the translations to create a preliminary experimental French-Canadian version.

Word structure and consonant interaction in a French-speaking child with protracted phonological development.

This paper presents data from a Québec French-speaking child with protracted phonological development (PPD) who received phonological intervention based on a nonlinear phonological framework. At 5;3, he showed relative strengths in word structure compared with consonants (e.g.
