Fractional ac Josephson effect in unconventional superconductors
For certain orientations of Josephson junctions between two px-wave or two d-wave superconductors,
 the subgap Andreev bound states produce a 4π-periodic relation between the Josephson
 current I and the phase difference:φ I sin(φ/2). Consequently, the ac Josephson current has the&am...

| description | For certain orientations of Josephson junctions between two px-wave or two d-wave superconductors,
the subgap Andreev bound states produce a 4π-periodic relation between the Josephson
current I and the phase difference:φ I sin(φ/2). Consequently, the ac Josephson current has the
fractional frequency eV h, where V is the dc voltage. In the tunneling limit, the Josephson current
is proportional to the first power (not square) of the electron tunneling amplitude. Thus, the
Josephson current between unconventional superconductors is carried by ingle electrons, rather
than by Cooper pairs. The fractional ac Josephson effect can be observed experimentally by measuring
frequency spectrum of microwave radiation from the junction
