Abstract
After reviewing the construction of the fuzzy sphere and the formulation of the scalar theory in this non-commutative setting, we address a detailed non-perturbative study by means of a novel algorithm, which strongly reduces the correlation problems in the matrix update process, and which allows the investigation of different regimes of the model in a precise and reliable way. We study the modes associated to different momenta and the rôle they play in the case when the potential admits classically degenerate minima, pointing out a consistent interpretation which is corroborated by our data, and which sheds further light on the results obtained in some previous works. We also investigate the effects of the non-commutative anomaly predicted in a one-loop perturbative analysis of the model, which is expected to induce a distortion of the dispersion relation on the fuzzy sphere.
