Superconductivity in dilute SrTiO: a review
Maria N. Gastiasoro, Jonathan Ruhman, Rafael M. Fernandes
Doped SrTiO, one of the most dilute bulk systems to display superconductivity, is perhaps the first example of an unconventional superconductor, as it does not fit into the sta…
Chiral superconductivity in the alternate stacking compound 4Hb-TaS
A. Ribak, R. Majlin Skiff, M. Mograbi +6
Layered van der Waals (vdW) materials are emerging as one of the most versatile directions in the field of quantum condensed matter physics. They allow an unprecedented control of…
Comment on "Superconductivity at low density near a ferroelectric quantum critical point: Doped SrTiO3"
Jonathan Ruhman, Patrick A. Lee
Wölfle and Balatsky Phys. Rev. B 98, 104505 (2018) have proposed a microscopic pairing mechanism for doped SrTiO (STO) based on the coupling of electronic…
Superconductivity near a ferroelectric quantum critical point in ultralow-density Dirac materials
Vladyslav Kozii, Zhen Bi, Jonathan Ruhman
The experimental observation of superconductivity in doped semimetals and semiconductors, where the Fermi energy is comparable to or smaller than the characteristic phonon frequenc…
