In the usual Ginzburg–Landau theory the critical value of Ginzburg–Landau parameter View the MathML source separates regimes of type-I and type-II superconductivity. The latter regime possess thermody...
An elusive state of matter called superconductivity could be realized in stacks of sheetlike crystals just a few atoms thick, a trio of physicists has determined.
In the superconductor LaRu$_3$Si$_2$ with the Kagome lattice of Ru, we have successfully doped the Ru with Fe and Co atoms. Contrasting behaviors of suppression to superconductivity is discovered betw...
We report thermal conductivity measurements down to 50 mK on Ca$_3$Ir$_4$Sn$_{13}$ single crystals, in which superconductivity with $T_c \approx 7$ K was claimed to coexist with ferromagnetic spin-flu...
The upper critical fields, $H_{c2}$($T$), of single crystals of the superconductor Ca$_{10}$(Pt$_{4-\delta}$As$_{8}$)((Fe$_{0.97}$Pt$_{0.03}$)$_{2}$As$_{2}$)$_{5}$ ($\delta$ $\approx$ 0.246) are deter...
We calculate corrections to the conventional result for the Coulomb pseudopotential in the theory of superconductivity. We find that retardation effects are still operative for higher order correction...
Superconductivity in the recently proposed ground-state structures of atomic metallic hydrogen is investigated over the pressure range 500 GPa to 3:5 TPa. Near molecular dissociation, the electron{pho...
Abstract: In this article two models for charges distributions are discussed. On the basis of our consideration we put different points of view for stationary state. We prove that only finite energy m...
We study a defect system of two parallel D5 probe branes in a large-N_c D3 background. Using the non-abelian DBI action, we study three different fields that can give rise to a superconducting phase t...
We report a systematic study on the influence of antiferromagnetic and ferromagnetic phases of Eu2+ moments on the superconducting phase upon doping the As site by isovalent P, which acts as chemica...
We report results of 59Co nuclear magnetic resonance measurements on a single crystal of super- conducting PuCoGa5 in its normal state. The nuclear spin-lattice relaxation rates and the Knight shifts...
Sr2IrO4 has been suggested as a Mott insulator from a single Jeff = 1/2 band, similar to the cuprates. However this picture is complicated by the measured large magnetic anisotropy and ferromagnetis...
Six months ago I was asked to write a personal history of my engagement with the high-Tc problem of the cuprate superconductors, in rather informal and autobiographical style. As the work proceeded I ...
It is shown that charge ordering in layered crystalline metals causes an increase in the normal state energy of the conducting layers. If this increase in the energy exceeds the difference between th...
The CeFeAsO and CeFePO iron pnictide compounds were studied via electrical transport measurements under high-pressure. In CeFeAsO polycrystals, the magnetic phases involving the Fe and Ce ions coexis...
