Open AccessNonlinear 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 fr...

Layer Hall effect in a 2D topological axion antiferromagnet
Whereas ferromagnets have been known and used for millennia, antiferromagnets were only discovered in the 1930s1. At large scale, because of the absence of global magnetization, antiferromagnets may seem to behav...

Hall effects in artificially corrugated bilayer graphene without breaking time-reversal symmetry
Strain can be used to modify the band structure—and thus the electronic properties—of two-dimensional materials. However, research has focused on the use of monolayer graphene with a limited lowering of spatia...
