Description

We study non-topological bright solitons in two-dimensional conformal field theory. Our analysis shows that these solitons exhibit only zero modes, with no vibrational or decay excitations. This behavior is explained by examining a relativistic extension of the model, where conformal symmetry is weakly violated and decay modes appear. Thus, the restoration of conformal symmetry ensures the remarkable stability of the solutions.
