强磁场中质子和中子性质的Skyrme模型研究

Skyrme model study of proton and neutron properties in a strong magnetic field

Bing-Ran He

摘要:

研究了均匀磁场中质子和中子的性质。Gell-Mann-Nishijima公式对于重子态是满足的。结果表明,随着磁场强度的增大,质子质量先减小后增大,而中子质量总是增大。质子和中子的磁矩之比随磁场强度的增大而增大。随着磁场强度的增大,质子的尺寸先增大后减小,而中子的尺寸总是减小。本文的分析表明,在磁星的核心部分,状态方程依赖于磁场,磁场改变了磁星的质量极限。

英文摘要:

The proton and neutron properties in a uniform magnetic field are investigated. The Gell-Mann-Nishijima formula is shown to be satisfied for baryon states. It is found that with increasing magnetic field strength, the proton mass first decreases and then increases, while the neutron mass always increases. The ratio between magnetic moment of proton and neutron increases with the increase of the magnetic field strength. With increasing magnetic field strength, the size of proton first increases and then decreases, while the size of neutron always decreases. The present analyse implies that in the core part of the magnetar, the equation of state depend on the magnetic field, which modifies the mass limit of the magnetar.
