论文摘要
与配对相互作用的强烈相关的费米系统在临界温度$ t_c $以下变成超氟。这种配对相关性在温度下改变液体的行为的程度$ t> t_c $是一个微妙的问题，它仍然是一个辩论的领域，特别是关于在BCS-BEC的bcs-bec交叉中出现的未固定旋转旋转$ 1/2 $非差异性问题的出现。为了阐明这一点，我们在统一限制及其周围提取了数量的关键重要性，即：使用非扰动，约束，限制性的量子量子型碳纤维量，总能量，旋转易感性，旋转易感性，配对相关函数，凝聚力分数和临界温度$ t_c $的奇怪的奇怪重要性。
Strongly correlated Fermi systems with pairing interactions become superfluid below a critical temperature $T_c$. The extent to which such pairing correlations alter the behavior of the liquid at temperatures $T > T_c$ is a subtle issue that remains an area of debate, in particular regarding the appearance of the so-called pseudogap in the BCS-BEC crossover of unpolarized spin-$1/2$ nonrelativistic matter. To shed light on this, we extract several quantities of crucial importance at and around the unitary limit, namely: the odd-even staggering of the total energy, the spin susceptibility, the pairing correlation function, the condensate fraction, and the critical temperature $T_c$, using a non-perturbative, constrained-ensemble quantum Monte Carlo algorithm.
