Pseudogap-induced asymmetric tunneling in cuprate superconductors

•We provide an explanation to the asymmetric tunneling in cuprate superconductors.•We reproduce qualitatively main features of the differential tunneling spectrum.•The asymmetric tunneling is a consequence due to the presence the pseudogap.•The symmetric tunneling spectrum recovers in the heavily ov...
