Strongly fluctuating moments in the high-temperature magnetic superconductor RbEuFeAs
K. Willa, R. Willa, J. -K. Bao +5
We report detailed specific heat measurements on the recently discovered magnetic superconductor RbEuFeAs. We investigated the superconducting transition at 37K and extract…
On the trace anomaly of a Weyl fermion in a gauge background
Fiorenzo Bastianelli, Matteo Broccoli
We study the trace anomaly of a Weyl fermion in an abelian gauge background. Although the presence of the chiral anomaly implies a breakdown of gauge invariance, we find that the t…
Nanocalorimetric Evidence for Nematic Superconductivity in the Doped Topological Insulator SrBiSe
Kristin Willa, Roland Willa, Kok Wee Song +6
Spontaneous rotational-symmetry breaking in the superconducting state of doped has attracted significant attention as an indicator for topological supe…
Peak effect due to competing vortex ground states in superconductors with large inclusions
Roland Willa, Alexei E. Koshelev, Ivan A. Sadovskyy +1
Superconductors can support large dissipation-free electrical currents only if vortex lines are effectively immobilized by material defects. Macroscopic critical currents depend on…
Anisotropic superconductivity and magnetism in single-crystal RbEuFeAs
M. P. Smylie, K. Willa, J. -K. Bao +11
We investigate the anisotropic superconducting and magnetic properties of single-crystal RbEuFeAs using magnetotransport and magnetization measurements. We determine a magn…
Interplay between orbital-quantization effects and the Fulde-Ferrell-Larkin-Ovchinnikov instability in multiple-band layered superconductors
Kok Wee Song, Alexei E. Koshelev
We explore superconducting instability for a clean two-band layered superconductor with deep and shallow bands in the magnetic field applied perpendicular to the layers. In the sha…
