论文摘要
我们研究了在存在狂欢偶联的情况下，研究了三维BCS-BEC交叉，该耦合强烈影响系统的多种特性，例如化学势，配对间隙和超流体密度。我们确定临界相互作用强度，在该系统下在零温度下也正常。最后，我们通过使用不同的理论方案来计算Rabi耦合对超流体到正常相变的临界温度的影响。
We investigate the three-dimensional BCS-BEC crossover in the presence of a Rabi coupling which strongly affects several properties of the system, such as the chemical potential, the pairing gap and the superfluid density. We determine the critical interaction strength, below which the system is normal also at zero temperature. Finally, we calculate the effect of the Rabi coupling on the critical temperature of the superfluid-to-normal phase transition by using different theoretical schemes.
