发现磁单极子存在？Observation of Dirac monopoles in ...

磁性是有两极的

磁单极子被发现如果是真的。大概,会有不得了的事情发生

想想磁铁只有一极。。。

一级咋了  还是不明

牛了。也许是未来的突破口。

怎么可能只有一极

我来装个x   其实跟去年3月份的德国某个组的成果类似，这个磁单极子只是通过凝聚态造出来的一个具有磁单极子性质的“准粒子”。并不是基本粒子形式存在的磁单极子。另外，磁单极子只是存在于超弦理论与量子场论中，不会与经典的麦克斯韦理论有太多冲突…没有什么太多需要改写，不如说，如果磁单极子不存在……好多理论才要改写呢……

一级咋了  还是不明
如果地球只有一极，理论上会塌缩成无限小的一个点

在一极世界面前，黑洞都会被吞噬

反重力？      

真发现了存在磁单极的话，将引领科技史上的一次巨大革命！

这个并不是粒子物理中的磁单极子,只是凝聚态的产物.可以用来研究monopole的性质,但是和基本粒子中的磁单极并不是一回事

电有电荷（质子，电子），对应就有磁荷，只是一直未发现。麦克斯韦方程已经考虑过磁荷了，理论早已成熟

楼上大神已科普

或许一个单子是单磁极，但是，如果要想得到足够大的磁体，就要把单磁极子叠加起来，这样实际上就又会变成2极了
所以，实际上这个发现没什么大的用处
以上只是胡侃几句哈

Although analogues of magnetic monopoles have been found in exotic spin ices5, 6 and other systems7, 8, 9, there has been no direct experimental observation of Dirac monopoles within a medium described by a quantum field, such as superfluid helium-3 (refs 10, 11, 12, 13). Here we demonstrate the controlled creation14 of Dirac monopoles in the synthetic magnetic field produced by a spinor Bose–Einstein condensate. Monopoles are identified, in both experiments and matching numerical simulations, at the termini of vortex lines within the condensate. By directly imaging such a vortex line, the presence of a monopole may be discerned from the experimental data alone. These real-space images provide conclusive and long-awaited experimental evidence of the existence of Dirac monopoles. Our result provides an unprecedented opportunity to observe and manipulate these quantum mechanical entities in a controlled environment.
