Fields as excitations of quantized coordinates
Fradkin E. S., Tseitlin A. A.
A method is proposed for constructing an effective action for fields corresponding to excitations of the quantized coordinates of extended objects (strings, membranes, etc.). In the low-energy limit, the effective action includes kinetic terms for the scalar field, the gravitational field, and the field of an antisymmetric tensor. The ground state of the theory is determined by the nontrivial vacuum values of these fields (so that, in particular, the tachyon problem in the theory of a Bose string is solved).
