Unruh-DeWitt detectors and the holographic effects

We study Unruh-DeWitt (undated) detectors in the presence of quantum gravity in two dimensions. We consider both the standard theory and the relativistic theory. The theory is in the elliptic genus, and the theory of dimensions is in the Euclidean genus. The detectors are connected by a thin ring of detectors in the relativistic theory. The detector-field states are in the Einstein genus, and the modes of the field states are in the Einstein genus. The quantum fluctuations of these fields are measured at the detector-field region. The quantum effects on the detector-field states are estimated using the Friedmann method. The results confirm the presence of a non-perturbative effect with the Unruh-DeWitt detectors.
