作者研究了富中子核物质的相图，允许四个竞争阶段。由此产生的相图具有两个三临界点，以及从BCS相到玻色-爱因斯坦氘核凝聚物加上中子气体的交叉。通过研究库珀对波函数和相关量来跟踪各个阶段的物理和从弱耦合到强耦合的过渡。
The authors examine the phase diagram of neutron-rich nuclear matter, allowing for four competing phases. The resulting phase diagram features two tricritical points as well as crossovers from the BCS phase to a Bose-Einstein deuteron condensate plus a neutron gas. The physics of the individual phases and the transition from weak to strong coupling is traced by examining the Cooper-pair wave function and related quantities.
