Query: Fermionic instantons   We demonstrate the existence of a broad class of non-perturbative fermionic
solutions to the Euclidean supergravity equations of motion, which are half-BPS
and nonsingular, possess zero action, and obey an (anti)self-duality condition.
These are identified as fermionic instantons associated to the status of the
gravitino as the gauge field of local supersymmetry. By explicitly constructing
these configurations from combinations of (anti)self-dual Yang-Mills gauge
fields and Killing spinors, we may leverage the ADHM method and generalisations
thereof to provide all possible solutions on certain gravitational backgrounds.
As one may expect, these solutions generate and are in turn intrinsically
dependent upon spacetime torsion.
