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…
Nicolai maps for super Yang-Mills on the light cone
Olaf Lechtenfeld
We construct Nicolai maps for supersymmetric Yang-Mills theory in four and ten spacetime dimensions in the light-cone gauge, where the elimination of non-propagating degrees of fre…
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…
The Nicolai-map approach to supersymmetry
Olaf Lechtenfeld
In 1980 Hermann Nicolai proposed a characterization of supersymmetric theories that became known as the Nicolai map. This is a particular nonlocal and nonlinear field transformatio…
