论文摘要
从理论上讲，我们研究了稀有中子物质中的中子 - α$ p $波的命运，这可能在中子星和超新星爆炸中遇到。虽然$^5 $他被称为一个共鸣状态，它在真空中腐烂到中子和一个α粒子，但这种不稳定状态在中子费米海中变成了稳定的结合状态，因为中子的pauli-blocking效应禁止衰减过程。通过覆盖效应的辅助辅助的这种共振到结合的过渡可以在冷原子实验中实现，以便在异核Feshbach共振附近的量子混合物进行量子混合物。
We theoretically investigate the fate of a neutron-alpha $p$-wave resonance in dilute neutron matter, which may be encountered in neutron stars and supernova explosions. While $^5$He is known as a resonant state that decays to a neutron and an alpha particle in vacuum, this unstable state turns into a stable bound state in the neutron Fermi sea because the decay process is forbidden by the Pauli-blocking effect of neutrons. Such a resonance-to-bound transition assisted by the Pauli-blocking effect can be realized in cold atomic experiments for a quantum mixture near the heteronuclear Feshbach resonance.
