论文摘要
关于旋转间隙化合物yb $ _2 $ si $ _2 $ o $ $ _7 $的粘合剂粘液胶片（BEC）的最新实验数据显示出不对称的BEC DOME ARXIV：1810.13096V2。我们在呼吸蜂窝晶格上检查了对海森堡模型的修改，这表明可以通过弱各向异性的竞争形式来解释这种物理学。我们采用了一系列分析和数值技术，以表明各向异性产生了从具有破裂的ISING对称性状态的野外驱动相变为损坏对称性并跨越极化极限的相。
Recent experimental data on Bose-Einstein Condensation (BEC) of magnons in the spin-gap compound Yb$_2$Si$_2$O$_7$ revealed an asymmetric BEC dome arXiv:1810.13096v2. We examine modifications to the Heisenberg model on a breathing honeycomb lattice, showing that this physics can be explained by competing forms of weak anisotropy. We employ a gamut of analytical and numerical techniques to show that the anisotropy yields a field driven phase transition from a state with broken Ising symmetry to a phase which breaks no symmetries and crosses over to the polarized limit.
