The comparison of simulations and experimental plots in the case of selective valley excitation of the K1' state. Black arrows marking the propagation direction and dashed triangular lines demarcating ...

Topological spin textures, spatially organized patterns linked to the intrinsic angular momentum of particles, have proved to be highly advantageous for the development of spintronics and quantum ...

Air cannons produce visible vortex rings by generating rotating air pressure differences, while electromagnetic cannons emit electromagnetic vortex pulses using coaxial horn antennas. The ...

In physics, topological singularities are highly stable structures that occur on a very small scale. Thanks to their winding geometry, they are extremely resistant to change. This remarkable stability ...

One example is the electric vortex, a microscopic 'whirlpool' formed by electric dipoles — regions where positive and negative charges are separated and depicted as tiny arrows — rotating in a ...
