Description:
Author(s): Zhicheng Zhong, Markus Wallerberger, Jan M. Tomczak, Ciro Taranto, Nicolaus Parragh, Alessandro Toschi, Giorgio Sangiovanni, and Karsten Held We employ density functional theory plus dynamical mean field theory and identify the physical origin of why two layers of SrVO 3 on a SrTiO 3 substrate are insulating: the thin film geometry lifts the orbital degeneracy, which in turn triggers a first-order Mott-Hubbard transition. Two layers of SrVO ... [Phys. Rev. Lett. 114, 246401] Published Tue Jun 16, 2015
