Superconductivity in the vicinity of a ferroelectric quantum phase transition

S. E. Rowley, C. Enderlein, J. Ferreira de Oliveira +4

Superconductivity has been observed in doped SrTiO $_{3}$ at charge-carrier densities below 10 $^{18}$ cm $^{- 3}$ , where the density of states at the Fermi level of the itinerant electr…

Ambient Pressure Structural Quantum Critical Point in the Phase Diagram of (Ca $_{x}$ Sr $_{1 - x}$ ) $_{3}$ Rh $_{4}$ Sn $_{13}$

S. K. Goh, D. A. Tompsett, P. J. Saines +5

The quasi-skutterudite superconductor Sr $_{3}$ Rh $_{4}$ Sn $_{13}$ features a pronounced anomaly in electrical resistivity at $T^{*} \sim$ 138 K. We show that the anomaly is caused by a secon…

The importance of anisotropic Coulomb interactions and exchange to the band gap and antiferromagnetism of β-MnO2 from DFT+U

David A. Tompsett, Derek S. Middlemiss, M. Saiful Islam

First principles density functional theory (DFT) is used to investigate the electronic structure of β-MnO2. From collinear spin polarized calculations we find that DFT+U_Eff predic…

Enhancement of the Superconducting Transition Temperature with Hydrostatic Pressure in Ca_{3}Ir_{4}Sn_{13} Single Crystals

Swee K. Goh, Lina E. Klintberg, Patricia L. Alireza +5

We report high pressure magnetic susceptibility and electrical resistivity measurements on Ca_{3}Ir_{4}Sn_{13} single crystals up to 60 kbar. These measurements allow us to follow…

The Role of Crystal Symmetry in the Magnetic Instabilities of $β$ -YbAlB $_{4}$ and $α$ -YbAlB $_{4}$

D. A. Tompsett, Z. P. Yin, G. G. Lonzarich +1

Density functional theory methods are applied to investigate the properties of the new superconductor $β$ -YbAlB $_{4}$ and its polymorph $α$ -YbAlB $_{4}$ . We utilize the generalized grad…
