The coupling flow for supergravity
Federico Arrighi, Saurish Khandelwal, Olaf Lechtenfeld
The paper derives a flow operator governing how quantum correlation functions in four‑dimensional Poincaré supergravity change with the gravitational coupling, using the superconfo…
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…
Nicolai maps with four-fermion interactions
Lorenzo Casarin, Olaf Lechtenfeld, Maximilian Rupprecht
Nicolai maps offer an alternative description of supersymmetric theories via nonlinear and nonlocal transformations characterized by the so-called `free-action' and `determinant-ma…
