论文摘要
我们研究了Dicke超高的热力学极限。我们找到了系统密度矩阵的表达式，我们可以证明在大原子数N的极限中精确。这与先前已知的解决方案相反，这些解决方案仅在数值上建立并且仅在多次范围内有效。当系统受到额外的激发衰减时，我们还引入了一个渐近精确的解决方案，因为这在实验中是常见的情况。
We investigate the thermodynamic limit of Dicke superradiance. We find an expression for the system's density matrix that we can prove is exact in the limit of large atom numbers N. This is in contrast to previously known solutions whose accuracy has only been established numerically and that are valid only for a range of times. We also introduce an asymptotically exact solution when the system is subject to additional incoherent decay of excitations as this is a common occurrence in experiment.
