On the concept of local invariance in the theory of spin glasses

I.E. Dzyaloshinsk, G.E. Volovik

(1978)

We consider the possibility of applying the concept of local exchange invariance (Yang-Mills fields [3]) to describe spin glasses. We start with the microscopic discrete local invariance and frustration concept studied by Toulouse [8] and Villain [7] and show that on the macroscopic level a spin glass is naturally described by continuous Yang-Mills fields. In particular, magnetic and electric fields have the meaning of density and current of disclinations. We also study types of long-range order, oscillation spectra and possible phase transitions in such systems.
