    RG flows and stability in defect field theories 

    Carreño Bolla, I.; Rodriguez-Gomez, D.; Russo, J. G. (Jorge Guillermo) (Data de publicació: 2025-04-25)

    Abstract: We investigate defects in scalar field theories in four and six dimensions in a double-scaling (semiclassical) limit, where bulk loops are suppressed and quantum effects come from the defect coupling. We compute ...
