Journal ArticleDOI
Turning a nickelate Fermi surface into a cupratelike one through heterostructuring.
Philipp Hansmann,Philipp Hansmann,Xiaoping Yang,Alessandro Toschi,Alessandro Toschi,Giniyat Khaliullin,Ole Krogh Andersen,Karsten Held +7 more
TL;DR: Using the local density approximation and its combination with dynamical mean-field theory, it is shown that electronic correlations induce a single-sheet, cupratelike Fermi surface for hole-doped 1/1 LaNiO3/LaAlO3 heterostructures, indicating that "orbital engineering" by means ofheterostructuring should be possible.
Journal ArticleDOI
A microscopic view on the Mott transition in chromium-doped V 2 O 3
Stefano Lupi,Leonetta Baldassarre,B. Mansart,Andrea Perucchi,Alexei Barinov,Pavel Dudin,E. Papalazarou,Fanny Rodolakis,Jean-Pascal Rueff,J. P. Itié,Sylvain Ravy,Daniele Nicoletti,Paolo Postorino,Philipp Hansmann,N. Parragh,Alessandro Toschi,Tanusri Saha-Dasgupta,Ole Krogh Andersen,Giorgio Sangiovanni,Kathryn D. Held,Marino Marsi +20 more
TL;DR: This work unveils for the first time the MIT in Cr-doped V(2)O(3) with submicron lateral resolution: with decreasing temperature, microscopic domains become metallic and coexist with an insulating background.
Journal ArticleDOI
Tracking the Footprints of Spin Fluctuations: A MultiMethod, MultiMessenger Study of the Two-Dimensional Hubbard Model

Kim,Evgeny Kozik,E. A. Stepanov,Anna Kauch,Sabine Andergassen,Philipp Hansmann,Daniel Rohe,Y. M. Vilk,James P.F. LeBlanc,Shiwei Zhang,Andre-Marie Tremblay,Michel Ferrero,Olivier Parcollet,Antoine Georges +25 more
TL;DR: In this paper, a comparative study of state-of-the-art quantum many-body methods is performed using the half-filled Hubbard model at weak coupling as testing grounds, with two numerically exact methods (diagrammatic and determinantal quantum Monte Carlo) serving as a benchmark.
Journal ArticleDOI
Dichotomy between Large Local and Small Ordered Magnetic Moments in Iron-Based Superconductors
Philipp Hansmann,Ryotaro Arita,Alessandro Toschi,Shiro Sakai,Giorgio Sangiovanni,Karsten Held +5 more
TL;DR: In this article, a four-band model for iron-based superconductors with local density approximation combined with dynamical mean-field theory (LDA+DMFT) was proposed.
Journal ArticleDOI
Long-range Coulomb interactions in surface systems: a first-principles description within self-consistently combined GW and dynamical mean-field theory.
TL;DR: A fully ab initio derivation of low-energy Hamiltonians for the adatom systems Si(111):X, with X=Sn, Si, C, Pb, that is solved within self-consistently combined GW and dynamical mean-field theory.
