半经典自旋阻尼：超辐射再探
Semiclassical spin damping: Superradiance revisited
摘要：
一个众所周知的描述超辐射从点状集合的许多原子涉及耗散运动的大自旋。相关的“超辐射主方程”允许一个正式的精确的解决方案，我们受到半经典的评价。线索是拉普拉斯逆变换的鞍点近似。所有以前的近似处理，不同的，因为他们可能会出现，都包含在我们的系统的制定。一个副产品是一个迄今为止未知的严格关系之间的连贯性和概率。我们的研究结果可以推广到自旋动力学与混沌在经典极限。
英文摘要：
A well known description of superradiance from pointlike collections of many atoms involves the dissipative motion of a large spin. The pertinent ``superradiance master equation'' allows for a formally exact solution which we subject to a semiclassical evaluation. The clue is a saddle-point approximation for an inverse Laplace transform. All previous approximate treatments, disparate as they may appear, are encompassed in our systematic formulation. A byproduct is a hitherto unknown rigorous relation between coherences and probabilities. Our results allow for generalizations to spin dynamics with chaos in the classical limit.
