The coupling flow for supergravity
Federico Arrighi, Saurish Khandelwal, Olaf Lechtenfeld
Quantum correlation functions in supersymmetric field theories can be encoded in the Nicolai map. The infinitesimal inverse map provides their response to a change in a coupling co…

Towards a Nicolai map for supergravity
Federico Arrighi, Saurish Khandelwal, Olaf Lechtenfeld
We investigate the possibility of a Nicolai map for minimal supergravity in four dimensions. Such a map would allow for the computation of quantum supergravity correlation function…

Nicolai maps for supersymmetric sigma models
Olaf Lechtenfeld
Supersymmetric field theories can be characterized by their Nicolai map, which is a nonlinear and nonlocal field transformation to their free-field limit. The systematic constructi…
