A team led by physicist Johannes Gooth at IBM Research near Zurich, Switzerland, say they have seen evidence for a long-predicted effect called the axial–gravitational anomaly. It states that huge gravitational fields — which general relativity describes as the result of enormous masses curving space-time — should destroy the symmetry of particular kinds of particles that usually come in mirror-image pairs, creating more of one particle and less of another. The kinds of conditions needed to prove this unusual breakdown of a fundamental ‘conservation law’ can’t be created in a laboratory. But the researchers exploited a peculiar parallel between gravity and temperature to create a lab analogue of the anomaly in niobium phosphide crystals. “This anomaly is so hard to measure that even indirect evidence is a major breakthrough,” says team member Adolfo Grushin of the University of California, Berkeley. Inside the crystal, the effect is as if a drawerful of pairs of gloves were suddenly to acquire an excess of right-handed gloves because some of the left-handed ones had switched handedness. The result, published in Nature2, bolsters an emerging view that quantum materials — crystals whose properties are dominated by quantum-mechanical effects – can act as experimental test-beds for physics effects that could only otherwise be seen under exotic circumstances.
