The Atiyah-Singer index theorem and the gauge field copy problem

Adonai S. Sant'Anna, Newton C. A. da Costa, Francisco A. Doria

K-theory allows us to define an analytical condition for the existence of `false' gauge field copies through the use of the Atiyah-Singer index theorem. After establishing that res…

Bounds on Correlation Functions of Quantum Rotators

Oscar Bolina, J. Rodrigo Parreira

We derive a McBryan-Spencer bound to the correlation function of a one-dimensional array of quantum rotators in the Villain approximation of the cosine interaction. We obtain the p…
