摘要：

The apparently unrelated experimental observations of optical sum rule violation(1) and of tunneling asymmetry in NIS tunneling(2) find a simple explanation within the theory of hole superconductivity. In fact, both phenomena were predicted by the theory long before they were experimentally observed(3,4). Other experimental predictions of the theory, in particular a novel feature expected in photoemission experiments, are discussed.
