Landau theory of superconducting phases in T_h crystals
S. H. Curnoe, I. A. Sergienko
We consider the Landau theory of phase transitions for multiple superconducting phases in T_h crystals. All possible phase transition sequences involving a single superconducting o…
Order parameter in superconductors with non-degenerate bands
I. A. Sergienko, S. H. Curnoe
In noncentrosymmetric metals, the spin degeneracy of the electronic bands is lifted by spin-orbit coupling. We consider general symmetry properties of the pairing function Delta(k)…
Theory of Metal-Insulator Transition in PrRu4P12 and PrFe4P12
S. H. Curnoe, H. Harima, K. Takegahara +1
All symmetry allowed couplings between the 4f^2-electron ground state doublet of trivalent praseodymium in PrRu4P12 and PrFe4P12 and displacements of the phosphorus, iron or ruthen…
Metallic "Ferroelectricity" in the Pyrochlore Cd2Re2O7
I. A. Sergienko, V. Keppens, M. McGuire +8
A class of materials known as ``ferroelectric metals'' was discussed theoretically by Anderson and Blount in 1965 [Phys. Rev. Lett. 14, 217 (1965)], but to date no examples of this…
Superconducting states in the tetrahedral compound PrOs4Sb12
I. A. Sergienko, S. H. Curnoe
We find possible superconducting states for tetrahedral (Th) symmetry crystals with strong spin-orbit coupling using Landau theory. Additional symmetry breaking within the supercon…
Structural order parameter and itinerant electron magnetism in Cd2Re2O7
I. A. Sergienko, S. H. Curnoe
We describe the low temperature behaviour of the magnetic susceptibility of Cd2Re2O7 in terms of a Landau theory of structural phase transitions. We calculate the zero temperature…
