作为暗能量的宇宙学Bardeen-Cooper-Schrieffer凝聚
Cosmological Bardeen-Cooper-Schrieffer condensate as dark energy
摘要：
我们认为，晚时加速的发生可以方便地描述一阶广义相对论协变耦合到费米子。暗能量是在早期宇宙中形成的费米子的巴丁-库珀-施里弗凝聚体。在后期，间隙和化学势演化为具有有效负压的状态方程，从而自然导致加速。
英文摘要：
We argue that the occurrence of late-time acceleration can conveniently be described by first-order general relativity covariantly coupled to fermions. Dark energy arises as a Bardeen-Cooper-Schrieffer condensate of fermions which forms in the early universe. At late times, the gap and chemical potential evolve to have an equation of state with effective negative pressure, thus naturally leading to acceleration.
