标题： Saturation properties of nuclear matter in the presence of strong magnetic field

摘要： 冷对称核物质在强磁场中的不同饱和性质已被考虑。 我们发现，对于大约为$B> 3 \times 10 ^ {17}\ G$、{对于有和没有核子异常磁矩的两种情况}的磁场，饱和密度和饱和能量随着磁场的增加而增加。 这表明对称核物质的磁化率变为负数，显示出抗磁响应，尤其是在$B< 3 \times 10 ^ {17}\ G$处。 我们发现，对于核物质，轨道磁化强度的大小比自旋磁化强度要高。 我们的结果表明，在足够高的磁场下，即$B> 3 \times 10 ^ {17}\ G$、{状态方程的软化是由朗道量子化引起的，但被核物质磁化带来的硬化所掩盖。}，我们已经表明强磁场对核物质的影响可能会改变通过应用实验可观测量得到的对称核物质状态方程的约束。 显示英文摘要

摘要： Different saturation properties of cold symmetric nuclear matter in the strong magnetic field have been considered. We have seen that for magnetic fields about $B> 3 \times 10 ^ {17}\ G$, {for both cases with and without nucleon anomalous magnetic moments}, the saturation density and saturation energy grow by increasing the magnetic field. It is indicated that the magnetic susceptibility of symmetric nuclear matter becomes negative showing the diamagnetic response especially at $B< 3 \times 10 ^ {17}\ G$. We have found that for the nuclear matter, the magnitude of orbital magnetization reaches the higher values comparing to the spin magnetization. Our results for the incompressibility show that at high enough magnetic fields, i.e. $B> 3 \times 10 ^ {17}\ G$, {the softening of equation of state caused by Landau quantization is overwhelmed by stiffening due to the magnetization of nuclear matter.} We have shown that the effects of strong magnetic field on nuclear matter may affect the constraints on the equation of state of symmetric nuclear matter obtained applying the experimental observable.
