• Abstract: 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.

  We investigate the effects of relative motion on entanglement harvesting by considering a pair of Unruh-Dewitt detectors moving at arbitrary, but independent, velocities. We find that the Negativity is a function of the relative velocity of the detectors, as well as their energy gaps and minimal separation.

  We show that it is possible to harvest quantum resources other than entanglement from a coherent field. For a detector moving at a constant velocity and with a mean radius of the same order as its transition wavelength, we observe that, for relativistic speeds, coherence swelling effects are present.

• Entanglement harvesting in the presence of a reflecting boundary [7.030564717893124]
  We study the entanglement harvesting of inertial and uniformly accelerated detectors locally interacting with vacuum massless scalar fields. We find that the presence of the boundary generally degrades the harvested entanglement when two detectors are very close to the boundary. Remarkably, the parameter space of the detectors' separation and the magnitude of acceleration that allows entanglement harvesting to occur is enlarged due to the presence of the boundary.

  This paper considers three inter-related adversarial inference problems involving cognitive radars. We first discuss inverse tracking of the radar to estimate the adversary's estimate of us based on radar's actions and calibrate the radar's sensing accuracy. Second, using revealed preference from microeconomics, we formulate a non-parametric test to identify if the cognitive radar is a constrained utility maximizer with signal processing constraints.
