It is shown that the conclusion of the Comment by C.Barone et al. [J. Appl. Phys. Vol.115, 116101 (2014)] on the paper [J. Appl. Phys. Vol.113, 094901 (2013)] is a result of several flaws including incorrect assumption that the charge…
We point out that the structure of the self-energy suggested in cond-mat/0208140 as a result of a ``non-perturbative analysis'' by ``purely mathematical means'' is incompatible with the very definition of the self-energy.

We study the Josephson current in a junction comprising two superconductors linked by a strong ferromagnet in presence of impurities. We focus on a regime where the electron (and hole) motion is ballistic over the exchange length and…
The standard approach to non-equilibrium thermodynamics describes transport in terms of generalised forces and coupled currents, a typical example being the Fourier law that relates temperature gradient to the heat flux. Here we demonstrate…
The Josephson effect can be regarded as a striking manifestation of exciton condensation. It has been suggested to tune the condensate phase of bilayer excitons by applying interlayer tunneling current. A poorly-understood phenomenon…
Josephson tunneling across a planar junction generally depends on the relative twist angle, $\theta$, between the two layers. However, if under a discrete rotation, the order parameter in one layer is odd and the other is even (as, e.g.,…

The question raised by [Bastin and Martin 2003 J. Phys. B: At. Mol. Opt. Phys. 36, 4201] is examined and used to explain in more detail a key point of our calculations. They have sought to rebut criticisms raised by us of certain techniques…
