Dimensionless Physics: Continuation
G. E. Volovik
Abstract
Abstract Several approaches to quantum gravity (including the model of superplastic vacuum; Diakonov tetrads emerging as the bilinear combinations of the fermionis fields; BF-theories of gravity; and effective acoustic metric) suggest that in general relativity the metric must have dimension 2, i.e., [gμν] = 1/[L]2, irrespective of the dimension of spacetime. This leads to the “dimensionless physics” discussed in [1]. Here we continue to exploit this unusual dimension of the metric.
