Model for superconductivity at any temperature

Mikhail Chapochnikov, Yannis Burnier, Eray Sabancilar

We construct a 2 + 1 dimensional model that sustains superconductivity at all temperatures. This is achieved by introducing a Chern-Simons mixing term between two Abelian gauge fields A and Z. The superfluid is described by a complex scalar charged under Z ...

Magnetotransport studies of superconducting Pr4Fe2As2Te1-xO4

László Forró, Bálint Náfrádi, Richard Gaal, Sergiy Katrych, Péter Szirmai, Andrea Pisoni

We report a study of the electrical transport properties of single crystals of Pr(4)Fe(2)As(2)Te(1-)xO(4), a recently discovered iron-based superconductor. Resistivity, Hall effect, and magnetoresistance are measured in a broad temperature range revealing ...

Single crystals of superconducting SmFeAsOHx: Structure and properties

László Forró, Alla Arakcheeva, Richard Gaal, Sergiy Katrych, Andrea Pisoni, Ping Huang, Péter Krisztián Matus

We report the synthesis, structure, and superconducting properties of single crystals of SmFeAsOHx. The crystals were grown at high pressure and high temperature using a cubic anvil technique. H-1-NMR studies confirm the presence of H atoms in the samples. ...

Three-dimensional momentum-resolved electronic structure of 1T-TiSe2: A combined soft-x-ray photoemission and density functional theory study

Helmuth Berger, Thorsten Schmitt

1T-TiSe2 is a quasi-two-dimensional transition metal dichalcogenide, which exhibits a charge density wave transition at a critical temperature of similar to 200 K as well as low-temperature superconductivity induced by pressure or intercalation. The electr ...

Bose-Einstein condensation of light in a cavity

Oleksandr Kriuchkov

The paper considers Bose-Einstein condensation (BEC) of light in a cavity with a medium. In the framework of a two-level model we show the effect of gaseous medium on the critical temperature of light condensation in the system. Transition of the system to ...

Superconductivity-Induced Transparency in Terahertz Metamaterials

A plasmonic analogue of electromagnetically induced transparancy is activated and tuned in the terahertz (THz) range in asymmetric metamaterials fabricated from high critical temperature (T-c) superconductor thin films. The asymmetric design provides a nea ...
