  author={Gian Luigi Alberghi and Roberto Casadio and Alessandro Gruppuso},
Non-minimally coupled scalar fields have been extensively used in the literature to account for higher loop quantum corrections to the theory of scalar fields in the general relativity theory of gravitation (see, e.g., [1] and Refs. therein). However, contrary to the minimally coupled case, quantization of such fields in the framework of quantum field… CONTINUE READING
