继较早的推导米勒，我们给出了一个简洁的推导赫尔曼-克鲁克传播，充分利用了辛结构的问题。我们还直接证明了Baranger及其同事得到的解冻高斯半经典传播子与线性化的Herman-Kluk传播子是等价的。
Following an earlier derivation by Miller, we give a concise derivation of the Herman-Kluk propagator that fully exploits the symplectic structure of the problem. We also show directly that the version of the thawed Gaussian semiclassical propagator obtained by Baranger and co-workers is equivalent to the linearized Herman-Kluk propagator.
