Non-Markovian dynamics revealed at the bound state in continuum

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 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 continuum.
