电动后核

Electrodynamic Metanuclei

Gregory Gabadadze, Rachel A. Rosen

摘要:

带电费米子和带相反电荷的大质量标量没有自相互作用的相对论系统,被认为有一个长寿命的集体状态与净电荷。电荷驻留在球对称态的表面附近,而内部由被费米子中和的凝聚标量组成。亚稳态是通过标量凝聚体的负压与主要由费米子引起的正压的竞争而实现的。我们认为这样的元核由氦-4原子核和电子组成,低于原子核但高于原子密度。典型的变核代表着原子大小、巨大质量、电荷和过剩能量的带电球。与普通的原子核不同,变核的电荷与其半径成正比。通过隧穿的量子力学衰减和通过对创建的真空不稳定性,都抑制了大值的电荷。类似的态也可以由其他带电(伪)标量组成,例如π介子、标量超对称伙伴,或者新物理学中的自旋0态。

英文摘要:

A relativistic system of electrically charged fermions and oppositely charged massive scalars with no self-interactions, is argued to have a long-lived collective state with a net charge. The charge is residing near the surface of the spherically-symmetric state, while the interior consists of the condensed scalars, that are neutralized by the fermions. The metastability is achieved by competition of the negative pressure of the scalar condensate, against the positive pressure, mainly due to the fermions. We consider such metanuclei made of helium-4 nuclei and electrons, below nuclear but above atomic densities. Typical metanuclei represent charged balls of the atomic size, colossal mass, electric charge and excess energy. Unlike an ordinary nucleus, the charge of a metanucleus scales proportionately to its radius. The quantum mechanical decay through tunneling, and vacuum instability via pair-creation, are both suppressed for large values of the electric charge. Similar states could also be composed of other charged (pseudo)scalars, such as the pions, scalar supersymmetric partners, or in general, spin-0 states of new physics.
