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 …

I review theoretical ideas and implications of experiments for the gap structure and symmetry
of the Fe-based superconductors. Unlike any other class of unconventional …

SrTiO3, a quantum paraelectric, becomes a metal with a superconducting instability after
removal of an extremely small number of oxygen atoms. It turns into a ferroelectric upon …

The nature of superconductivity in SrTiO3, the first oxide superconductor to be discovered,
remains a subject of intense debate several decades after its discovery. SrTiO3 is also an …

The theoretical understanding of the spin-orbit coupling (SOC) effects at LaAlO 3/SrTiO 3
interfaces and SrTiO 3 surfaces is still in its infancy. We perform first-principles density …

Paramagnets on the border of ferromagnetism at low temperatures are more subtle and
complex than anticipated by the conventional theory of quantum critical phenomena. Could …

The origin of superconductivity in bulk SrTiO 3 is a mystery since the nonmonotonous
variation of the critical transition with carrier concentration defies the expectations of the …

In doped SrTiO 3 superconductivity persists down to an exceptionally low concentration of
mobile electrons. This restricts the relevant energy window and possible pairing scenarios …

Two-dimensional electron gases (2DEGs) at oxide interfaces may exhibit unique properties,
including effects from strong electron correlations, extremely high electron densities …

Strontium titanate is a wide-gap semiconductor avoiding a ferroelectric instability thanks to
quantum fluctuations. This proximity leads to strong screening of static Coulomb interaction …
