论文摘要
我们研究了与基础旋转对称性的相互作用旋转系统的平均场溶液的变异扰动。引入了基于Majorana恒星代表的混合状态和群体理论的方法。该方法显着降低了扰动自由度的未知程度，使我们对新兴物理现象进行了简化而直接的探索。我们将其应用于表征自旋-1玻色 - 因子凝结物的相位，并用熵研究这些相的行为。还研究了在Hartree-fock近似中进行的Spin-2相图，其中预测环状新的相边界与温度的非线性偏差。
We study the variational perturbations for the mean-field solution of an interacting spinor system with underlying rotational symmetries. An approach based upon the Majorana stellar representation for mixed states and group theory is introduced to this end. The method reduces significantly the unknown degrees of freedom of the perturbation, allowing us a simplified and direct exploration on emergent physical phenomena. We apply it to characterize the phases of a spin-1 Bose-Einstein condensate and to study the behavior of these phases with entropy. The spin-2 phase diagram was also investigated within the Hartree-Fock approximation, where a non-linear deviation of the cyclic-nematic phase boundary with temperature is predicted.
