The ordinary quantum theory points out that general relativity (GR) is negligible for spatial distances up to the Planck scale lP=(hG/c3)1/2∼10−33cm. Consistency in the foundations of the quantum theory requires a “soft” spacetime structure of the GR at essentially longer length. However, for some reasons this appears to be not enough. A new framework (“superrelativity”) for the desirable generalization of the foundation of quantum theory is proposed. A generalized nonlinear Klein-Gordon equation has been derived in order to shape a stable (...) wave packet. (shrink)

The deterministic process of the detection of a single quantum of energy in Bohm's approach to quantum field theory is illustrated using the Jaynes-Cummings model with a scalar field. The nonlocality of differing quantum states of the scalar field is also explored, and this description is compared with the causal picture of an unquantized field acting on the detector.
