Origin of the anomalies: the modified Heisenberg equation
J. G. Esteve
The origin of the anomalies is analyzed. It is shown that they are due to the fact that the generators of the symmetry do not leave invariant the domain of definition of the Hamilt…

Vacuum Nodes and Anomalies in Quantum Theories
M. Aguado, M. Asorey, J. G. Esteve
We show that nodal points of ground states of some quantum systems with magnetic interactions can be identified in simple geometric terms. We analyse in detail two different archet…

Rigorous Analysis of Renormalization Group Pathologies in the 4-State Clock Model
M. Asorey, J. G. Esteve, R. Fernandez J. Salas
We perform an exact renormalization-group analysis of one-dimensional 4-state clock models with complex interactions. Our aim is to provide a simple explicit illustration of the be…
