We study the question of the Ward identity for “large” gauge invariance in 0+1 dimensional theories. We derive the relevant Ward identities for a single flavor fermion and a single flavor complex scalar field interacting with an Abelian gauge field. These identities are nonlinear. The Ward identity for any other complicated theory can be derived from these basic sets of identities. However, the...

In contrast to recent claims by Enss, Henkel, Picone, and Schollwöck [J. Phys. A 37, 10479] it is shown by numerical simulations that the autoresponse function of the critical 1+1-dimensional contact process is not in agreement with the predictions of local scale invariance.
