When a black hole spins rapidly, it drags the space around it, akin to a whirlpool in water. This phenomenon is called ...

The left side illustrates a schematic of electric field observation of the space charge layer at the grain boundary. An electron beam tilted at various angles (tilt-scan-averaged electron beam) scans ...

Schematic illustrations of (a) head-to-head (H-H) and (b) tail-to-tail (T-T) domain walls, respectively. These domain walls carry opposite polarization bound charges at their cores. In this study, a ...
