Symmetry and Gap Classification of the non-symmorphic SrPtAs
Mark H. Fischer, Jun Goryo
The hexagonal superconductor SrPtAs exhibits time-reversal-symmetry breaking below , hinting at an unconventional pairing state. Therefore, the symmetry of the underlying crys…
Nematic and spin-charge orders driven by hole-doping a charge-transfer insulator
Mark H. Fischer, Si Wu, Michael Lawler +2
Recent experimental discoveries have brought a diverse set of broken symmetry states to the center stage of research on cuprate superconductors. Here, we focus on a thematic unders…
Spin Transfer Torque Generated by the Topological Insulator Bi_2Se_3
A. R. Mellnik, J. S. Lee, A. Richardella +8
Magnetic devices are a leading contender for implementing memory and logic technologies that are nonvolatile, that can scale to high density and high speed, and that do not suffer…
Identifying the `Fingerprint' of Antiferromagnetic Spin-Fluctuations on Iron-Pnictide Superconductivity
Milan P. Allan, Kyungmin Lee, Andreas W. Rost +9
Cooper pairing in the iron-based high-Tc superconductors is often conjectured to involve bosonic fluctuations. Among the candidates are antiferromagnetic spin-fluctuations and d-or…
Superconducting proximity effect in topological metals
Kyungmin Lee, Abolhassan Vaezi, Mark H. Fischer +1
Much interest in the superconducting proximity effect in three-dimensional (3D) topological insulators (TIs) has been driven by the potential to induce Majorana bound states at the…
Effects of surface-bulk hybridization in 3D topological `metals'
Yi-Ting Hsu, Mark H. Fischer, Taylor L. Hughes +2
Identifying the effects of surface-bulk coupling is a key challenge towards exploiting the topological nature of the surface states in many available three-dimensional topological…
