论文摘要
在费米对凝结和激子凝结方面已经进行了广泛的理论和实验研究,作为不同类别的bose-Einstein样凝结。在这项工作中,存在Fermion-Exciton冷凝物---单个量子状态,在该量子状态下,Fermion对和激子冷凝水的特征共存 - - 在低粒子 - 数字($ n $)限制($ n $)的限制和理论上以大$ N $热力学限制为基础。费米昂(Fermion)对和fermion-exciton冷凝物的激子特征之间的权衡表明本质上是椭圆形的。讨论了Fermion-Exciton冷凝物的性能可能是Fermion对冷凝物和激子冷凝物的性质的混合,并且预计这一新的冷凝物的未来实验性和计算探索可能在超级调节器的双层中可以实现。
Extensive theoretical and experimental investigation has been conducted on fermion pair condensation and exciton condensation as distinct classes of Bose-Einstein-like condensation. In this work, the existence of a fermion-exciton condensate---a single quantum state in which character of both fermion pair and exciton condensates coexist---is established computationally in the low-particle-number ($N$) limit and theoretically in the large-$N$ thermodynamic limit. The trade-off between the fermion pair and excitonic character of the fermion-exciton condensate is shown to be elliptic in nature. The possibility that the properties of fermion-exciton condensates could be a hybrid of the properties of fermion pair condensates and exciton condensates is discussed, and future experimental and computational exploration of this new class of condensate, which may potentially be realizable in a bilayer of superconductors, is anticipated.
