Games and physics simulations need to detect which objects are touching or overlapping. With nnn objects, checking every pair is O(n2)O(n^2)O(n2) comparisons, which gets expensive fast. A hundred objects means roughly 5,000 pair checks. A thousand means nearly 500,000.
An Mn3Sn homo-junction enables efficient field-free full switching of chiral antiferromagnets with greatly reduced power consumption, advancing their potential for energy-efficient magnetic memory devices with advantages of ultradense integration and ultrafast speed.，更多细节参见51吃瓜
