Abstract: Density functional theory calculations reveal the existence of different correlated-electron ground states in (111)-oriented n-type LaAlO_(3)/SrTiO_(3) symmetric superlattices. They can be tuned by selecting the SrTiO3 thickness, and range from a trivial metal for thick… read more here.

Abstract: We discuss noncollinear magnetic phenomena whose local order parameter is characterized by more than one spin vector. By focusing on the simple cases of 2D triangular and 3D pyrochlore lattices, we demonstrate that their low-energy… read more here.

DOI: 10.3390/nano13020238
Abstract: The discovery of high-Tc superconductivity in cuprates in 1986 moved strongly correlated systems from exotic worlds interesting only for pure theorists to the focus of solid-state research. In recent decades, the majority of hot topics… read more here.
