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 …

Abstract In LaAlO3/SrTiO3 heterostructures, a gate tunable superconducting electron gas is
confined in a quantum well at the interface between two insulating oxides. Remarkably, the …

We present a new experimental approach to investigate the magnetic properties of the
anisotropic heavy-fermion system YbRh 2 Si 2 as a function of crystallographic orientation …

Many-body systems, composed of a macroscopic ensemble of mutually interacting particles,
can show very different physical properties with respect to their individual microscopic …

Superconductors are characterized by several energy scales such as the critical
temperature or the superconducting energy gap that characterizes the Cooper-pair …

Supraleitung in korrelierten Elektronensystemen in Ubergangsmetall-Oxiden ist ein
faszinierendes und komplexes Phänomen, welches in den vergangenen drei Jahrzenten …
