We consider two-dimensional weakly bound heterospecies molecules formed in a Fermi-Bose mixture with attractive Fermi-Bose and repulsive Bose-Bose interactions. Bosonic exchanges lead to an intermolecular attraction, which can be controlled and tuned to a p-wave resonance. Such attractive fermionic molecules can be realized in quasi-two-dimensional ultracold isotopic mixtures. We show that they are stable with respect to the recombination to deeply bound molecular states and with respect to the formation of higher-order clusters (trimers, tetramers, etc.).
我们考虑在具有吸引力的费米-玻色子相互作用和排斥的玻色-玻色相互作用的费米-玻色混合物中形成的二维弱束缚异种族分子。玻色子交换导致分子间吸引力，可以对其进行控制和调谐到 p 波共振。这种有吸引力的费米子分子可以在准二维的超冷同位素混合物中实现。我们表明，它们相对于深束缚分子态的复合以及相对于更高阶团簇（三聚体、四聚体等）的形成是稳定的。
