| Popis: | We study the properties of the transition probability for a circularly accelerated detector which interacts with the massless scalar fields in the presence of a reflecting boundary. As trajectory radius increases, the transition probability may exist some peaks in special circumstances, which lead to the possibility of same result for different trajectory radius with the same acceleration and energy gap. These behaviors can be characterized by some critical values. Furthermore, we analyze the entanglement harvesting phenomenon for two circularly accelerated detectors with a boundary. We consider that the two detectors are rotating around a common axis with the same acceleration, trajectory radius and angular velocity. When the detectors are close to the boundary, there may exist two peaks for entanglement harvesting. Interestingly, as trajectory radius increases, entanglement harvesting in some situations first decreases to zero, then maintains zero, and finally increases to a stable value. For a small energy gap, as the distance between the two detectors increases, the entanglement harvesting first takes zero at a larger distance between detectors and the boundary.
