Caption

Left: movement of light in a strong gravitational field in the universe. Middle: non-Ohmic conduction arising from a non-trivial quantum-metric structure of the "electron universe", which is tunable via the magnetic texture of Mn3Sn and leads to a second-order Hall effect. Right: conventional Ohmic conduction accompanied by a trivial quantum-metric structure.
