  "abstract": "The superconducting diode effect manifests as nonreciprocal properties of critical currents, yet a systematic tensorial framework for its symmetry-governed responses remains lacking. We develop such a framework by relating the angular harmonics of critical currents to the magnetic field. Crystalline symmetries constrain the dipolar response to be purely antisymmetric (Hall-like) in Rashba superconductors with $C_{3v}$, $C_{4v}$, or $C_{6v}$ symmetry, whereas they require a diagonal, traceless tensor in Dresselhaus superconductors with $D_{2d}$ symmetry. For systems with fourfold symmetry, the octupole response appears at linear order, whose response tensors take symmetric off-diagonal and identity forms for $C_{4v}$ and $D_{2d}$ symmetries, respectively. Furthermore, nematicity activates otherwise forbidden tensor components, providing a sensitive probe of rotational symmetry breaking in superconductors. At cubic order in the magnetic field, the nonlinear response tensors likewise exhibit distinct symmetry-dependent patterns. Our framework establishes a symmetry-resolved characterization of the superconducting diode effect and provides a route to probing the underlying electronic structure and symmetry-breaking orders.",
