Six years in 120 pages: Researchers shed light on Ricci flows

Differential geometry is the study of space geometry. Multiple natural phenomena, from universal expansion to thermal expansion and contraction, can come down to spatial evolution. The two core conjectures in this field, ...

In-plane antiferromagnets host a rich class of particle-like spin textures

Compared with the chiral spin textures in ferromagnets, their antiferromagnetic counterparts can be manipulated by spin currents with a more direct approach due to the absence of the skyrmion Hall effect, and much lower power ...

Fractal study describes COVID-19 transmission pattern

The most widely used model to describe the epidemic evolution of a disease over time is called SIR, short for susceptible (S), infected (I), and removed (R). A susceptible person can be infected, and the infected person will ...
