We present the in-plane and c-axis penetration depths of the underdoped cuprates. The pseudogap phase is addressed within the framework of the ordered d-density wave (DDW). The above scenario is considered using a mean-field calculation of the tight binding model which incorporates two types of...

Along the lines of Blonder, Tinkham and Klapwijk, we investigate the charge transport through ferromagnet/two-dimensional electronic gas/d-wave superconductor (F/2DEG/S) junctions in the presence of Rashba spin-orbit (SO) coupling and focus our attention on the interplay between spin...

A Cooper pair from a s-wave superconductor (S) entering a conventional charge density wave (CDW) below the Peierls gap dephases on the Fermi wavelength while one particle states are localized on the CDW coherence length ξ<Subscript>CDW</Subscript>. It is thus practically impossible to observe a Josephson current...</subscript>

We theoretically calculate the Josephson current for two superconductor/ferromagnetic semiconductor (SC/FS) bilayers separated by a semiconductor (SM) layer. It is found that the critical Josephson current I<Subscript>C</Subscript> in the junction is strongly determined by not only the relative orientations of the...</subscript>

Four-component Bogoliubov-de Gennes equations are applied to study tunneling conductance spectra of ferromagnet/ferromagnet/d-wave superconductor (F<Subscript>1</Subscript>/F<Subscript>2</Subscript>/d-wave S) tunnel junctions and to find out signs of spin-triplet pairing correlations induced in the proximity structure. The pairing...</subscript></subscript>
