【 摘 要 】

We demonstrate that the formation of a chiral d-density wave state generates a topological Meissner effect (TME) in the absence of any kind of superconductivity. The TME is identical to the usual superconducting Meissner effect, but it appears only for magnetic fields perpendicular to the plane while it is absent for in-plane fields. The observed enhanced diamagnetic signals in the nonsuperconducting pseudogap regime of the cuprates may find an alternative interpretation in terms of the TME, originating from a chiral d-density wave pseudogap.
