2 + 1 dimensional de Sitter universe emerging from the gauge structure of a nonlinear quantum system
Berry phases and gauge structures are fundamental quantum phenomena. In linear quantum mechanics the gauge field in parameter space presents monopole singularities where the energy levels become degenerate. In nonlinear quantum mechanics, which is an effective theory of interacting quantum systems,...
