Theta-vacuum and large N limit in CP^{N-1} sigma models
Miguel Aguado, Manuel Asorey
The theta dependence of the vacuum energy density in CP^{N-1} models is re-analysed in the semiclassical approach, the 1/N expansion and arguments based on the nodal structure of v…

Nahm Transform and Moduli Spaces of CPn Models on the Torus
M. Aguado, M. Asorey, A. Wipf
There is a Nahm transform for two-dimensional gauge fields which establishes a one-to-one correspondence between the orbit space of U(N) gauge fields with topological charge k defi…

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…
