宇宙磁振子铁磁凝聚产生的暗能量

Dark Energy from ferromagnetic condensation of cosmic magninos

Urjit A. Yajnik

摘要:

有人提出,一个超轻的费米子物种,被称为宇宙magnino已经凝聚成一个铁磁态的宇宙。与这种铁磁性相关的畴壁的延伸结构解释了观测到的暗能量。在修改的情况下,与电子气,它提出了斯通纳标准是满足由于磁偶极排斥。宇宙学的要求,然后产生一个较低的界限上的磁矩的宇宙magnino。提出的磁性应该与一种新的非标准电磁学相关联。如果在这种电磁作用下,磁尼诺也是带电的,那么相应的带相反电荷的较重物质将部分或全部解释宇宙中的暗物质。

英文摘要:

It is proposed that an ultra-light fermionic species, dubbed cosmic magnino has condensed into a ferromagnetic state in the Universe. The extended structure of domain walls associated with this ferromagnetism accounts for the observed Dark Energy. In modification of the situation with an electron gas, it is proposed that the Stoner criterion is satisfied due to magnetic dipolar repulsion. The cosmological requirements then yeild a lower bound on the magnetic moment of the cosmic magnino. The proposed magnetism is supposed to be associated with a new non-standard electromagnetism. If the magnino is also electrically charged under this electromagnetism, the corresponding oppositely charged heavier species would account partially or entirely for the Dark Matter in the Universe.
