摘要翻译：
我们研究了外场中一维强吸引三组分超冷费米子中的三角子、配对和量子相变的性质。由Bethe ansatz解解析地得到了基态能量、临界场、磁化强度和相图的精确结果。在塞曼分裂的驱动下，系统呈现出三角子、束缚对、正常费米液体和这些态的四种混合物的奇异相。特别地，当最高超精细能级与两个较低能级分离时，会发生从三电子相到配对相的平滑相变。相反，当最低能级从两个较高能级分离时，有一个从三电子相到正常费米液体的平滑相变。

英文摘要：
We investigate the nature of trions, pairing and quantum phase transitions in one-dimensional strongly attractive three-component ultracold fermions in external fields. Exact results for the groundstate energy, critical fields, magnetization and phase diagrams are obtained analytically from the Bethe ansatz solutions. Driven by Zeeman splitting, the system shows exotic phases of trions, bound pairs, a normal Fermi liquid and four mixtures of these states. Particularly, a smooth phase transition from a trionic phase into a pairing phase occurs as the highest hyperfine level separates from the two lower energy levels. In contrast, there is a smooth phase transition from the trionic phase into a normal Fermi liquid as the lowest level separates from the two higher levels.
