A numerical relaxation approach for solving the general Ginzburg-Landau equations for type-II superconductors is developed. It is erst applied to an isotropic type-II superconductor near H, & in order to establish the reliability and effectiveness of this approach. The strength of this approach should be in dealing with anisotropic and/or inhomogeneous systems. As an initial test of this streng...

background : diabetes mellitus is a metabolic disorder and is considered as the sixth most common cause of mortality. hospital readmission in patients with diabetes is important and can impose great costs on the health system. therefore, this study investigated factors affecting the readmission of patients with type ii diabetes to selected hospitals in kermanshah, iran, in 2012. methods: this w...

We study the finite temperature electroweak phase transition in an external hypercharge U(1) magnetic field HY , using lattice Monte Carlo simulations. For sufficiently small fields, HY /T 2 <∼ 0.3, the magnetic field makes the first order transition stronger, but it still turns into a crossover for Higgs massesmH <∼ 80 GeV. For larger fields, we observe a mixed phase analogous to a type I supe...

It has been shown that a gravitational dual to a superconductor can be obtained by coupling anti-de Sitter gravity to a Maxwell field and charged scalar. We review our earlier analysis of this theory and extend it in two directions. First, we consider all values for the charge of the scalar field. Away from the large charge limit, backreaction on the spacetime metric is important. While the qua...

It is expected that in the interior of compact stars a proton superconductor coexists with and couples to a neutron superfluid. Starting from a field-theoretical model for two complex scalar fields – one of which is electrically charged – we derive a GinzburgLandau potential which includes entrainment between the two fluids and temperature effects from thermal excitations of the two scalar fiel...

The superconductors with the Ginzburg-Landau (G-L) parameter ($\kappa$) $\sim1/\sqrt{2}$ exist near a critical Bogolomonyi (B) point where they show inter-type domains between type-I and type-II superconductivity. While such physics is well understood for isotropic superconductors, experimental investigation of anisotropic B-point remains an unattained goal mainly due to unavailability model ma...

superconductor fault current limiter (sfcl) is an effective device to suppress high fault currents. this paper presents a comparative study of resistive and inductive fault current limiters from transient stability point of view.  appropriate location and type of the limiters in a hv substation is selected by a qualitative approach based on the equal area criterion. study system is simulated by...

A feasible strategy to realize the Majorana fermions is searching for a simple compound with both bulk superconductivity and Dirac surface states. In this paper, we performed calculations of electronic band structure, Fermi states, as well measured resistivity, magnetization, specific heat TlSb CsCl-type structure. The structure show that semimetal when spin-orbit coupling taken into account. M...
