In Quantum Field Theory (QFT), the scattering amplitudes are central to learn about the interaction various field species, which participate in a process. These interactions give rise to many interesting quantum phenomenon, which many of the time we can study through perturbation techniques. Otherwise one has to resort non-perturbative techniques such as effective field theory. In a real experimental run we get only the overall amplitude for a transition from which we try to test the validity of perturbative sturcture.If the perturbative methods are uinder control in a theory then the higher order effects are typically successively subdued. This makes it difficult to verify if the higher order affects are indeed of the structure in which the theory predicts them to be. In this study we propose to fgenerate cavity environment which can be tuned fir specifically amplifying different terms in an interacting theory. A cavity offers boundary conditions, which through specific choice of resonance frequency brings ina controllable parameter into the picture which can be utilized to identify a particular transition element. A high quality factor cavity theoretically supports modes near a given value efficiently while away from the resonance the modes are marginally supported. Thus if there are loop level effects in an interacting theory which contribute to a specific frequency other than the tree level contribution, it is possible to relatively enhance that using the cavity resonance judiciously. Such an effect has recently been shown to be efficient in enhancing the non-inertial frames which are typically heavily supressed in free space. In addition if the frame is an accelerating one, this further provides an additional parameter to control the density of mode distributions. The proposed study advocates fr using both these features to selectively enhance and identify loop level effects as well as quantum gravity effects in such controlled environment.
