Superconductivity in dilute SrTiO3: A review

MN Gastiasoro, J Ruhman, RM Fernandes - Annals of Physics, 2020 - Elsevier
Doped SrTiO 3, 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 standard …

Anisotropic superconductivity mediated by ferroelectric fluctuations in cubic systems with spin-orbit coupling

MN Gastiasoro, TV Trevisan, RM Fernandes - Physical Review B, 2020 - APS
