Abstract
The nonsaturating, four-peak pattern of induced torque observed in spherical potassium samples has been a challenging puzzle for many years. It is found that this behavior can be quantitatively explained by an anisotropic Hall coefficient. This provides further confirmation of the broken translation symmetry of the ground state of potassium, i.e., a charge-density-wave structure.
