Using the microscopic formalism of Eilenberger equations, a three-band Ginzburg-Landau theory for the intraband dirty limit and clean interband scattering case is derived. Within the framework of this three-band Ginzburg-Landau theory, expressions for the critical temperature T
Dendritic flux avalanches is a frequently encountered consequence of the thermomagnetic instability in type-II superconducting films. The avalanches, which are potentially harmful for superconductor-based devices, can be suppressed by an adjacent normal metal layer, even when the two layers are...
We study the temperature and impurity effects of the ground state energy and the ground state binding energy in an anisotropic quantum dot by using the linear combination operator method. We also discuss the relations of the vibrational frequency and the mean number phonons varying with the...
In the present work the case of a chromium Bose–Einstein condensate is considered. The model includes not only the presence of the so-called contact interaction but also a long range and anisotropic dipole–dipole interaction has been included. Some thermodynamical properties are analyzed. For...
We theoretically study the electronic transport properties of Dirac fermions through one and double triangular barriers in graphene nanoribbon. Using the transfer matrix method, we determine the transmission, conductance and Fano factor. They are obtained to be various parameters dependent such...
We present the effect of A-site double doping (La0.254Y0.746) on elastic and thermal properties of EuVO3 in a wide doping range (0≤x≤1), using a modified rigid ion model (MRIM). Various lattice distortions and their relation to bulk modulus has been investigated systematically. The effect of the...
This paper calculates the oscillation period of an electron by using variational method of Pekar type on the condition of electric-LO-phonon strong coupling in a triangular bound potential quantum dot. It obtains the eigenenergies of the ground state and the first excited state, the...
The proximity effect in MoRe/Al sandwiches with different critical temperatures T
of MoRe films has been studied. The estimation of the proximity effect parameters has been made and their dependence on the Al thickness built. Features associated with instability of nonequilibrium...
There are indications that some high temperature unconventional superconductors have a “complex” d-wave order parameter (with an admixture of s-wave) leading to nonzero energy gap. Since the coherence length is short and the Fermi energy is relatively small the quasiclassical approach is...
