我们提出了一种有条理的方法来控制和增强量子和光学系统中指数衰减的偏差，方法是利用最近围绕另一种微妙效应的进展：连续体中的束缚态，这在过去十年中已经在光波导阵列实验中观察到。具体来说，我们表明，通过填充一个初始状态正交的束缚态的连续，它是可能的工程系统参数，通常的指数衰减过程被抑制有利于逆幂律动力学和相干效应，通常是非常难以检测的实验。我们证明了我们的方法使用基于光波导阵列实验的模型，并进一步表明，该方法是强大的，即使在面对显着失谐的精确位置的束缚态在连续。
We propose a methodical approach to controlling and enhancing deviations from exponential decay in quantum and optical systems by exploiting recent progress surrounding another subtle effect: the bound states in the continuum, which have been observed in optical waveguide array experiments within this past decade. Specifically, we show that by populating an initial state orthogonal to that of the bound state in the continuum, it is possible to engineer system parameters for which the usual exponential decay process is suppressed in favor of inverse power law dynamics and coherent effects that typically would be extremely difficult to detect in experiment. We demonstrate our method using a model based on an optical waveguide array experiment and further show that the method is robust even in the face of significant detuning from the precise location of the bound state in the continuum.
