IS THE CONDENSATION OF STRINGS THE ORIGIN OF EINSTEIN GRAVITY?

Abstract

We propose a mechanism to generate the metric in which the Kalb-Ramond symmetry existing in the topological BF theory is broken through the condensation of the string fields which are so introduced as to couple the antisymmetric tensor fields B, invariantly under the Kalb-Ramond symmetry. In the chiral decomposition of the local Lorentz group, the non-Abelian B fields need to be generalized to the string fields. The mechanism of the condensation is discussed, in view of the confinement problem and the polymer physics.
