Photon-assisted tunneling through a regular B-form single-stranded DNA with Majorana zero modes

Using nonequilibrium Green's function method, we investigate the transport properties through a regular B-form single-stranded DNA with Majorana zero modes in the presence of a microwave field. The photon-coupled Majorana zero mode acts as a series of channels in which Majorana zero mode can absorb (emit) photons. These channels present in the spectral function as a series of stripes, generating the corresponding photon peaks in the tunneling spectroscopy. The photon-assisted processes with Majorana zero mode can be regulated by gate voltage. This provides a method for detecting the existence of non-zero energy Majorana zero modes in organic molecule.
