Optical properties of LaNiO3 films tuned from compressive to tensile strain
I. Ardizzone, M. Zingl, J. Teyssier +11
Materials with strong electronic correlations host remarkable -- and technologically relevant -- phenomena such as magnetism, superconductivity and metal-insulator transitions. Har…
Legendre-spectral Dyson equation solver with super-exponential convergence
Xinyang Dong, Dominika Zgid, Emanuel Gull +1
Quantum many-body systems in thermal equilibrium can be described by the imaginary time Green's function formalism. However, the treatment of large molecular or solid ab inito prob…
NESSi: The Non-Equilibrium Systems Simulation package
Michael Schüler, Denis Golež, Yuta Murakami +5
The nonequilibrium dynamics of correlated many-particle systems is of interest in connection with pump-probe experiments on molecular systems and solids, as well as theoretical inv…
Strongly correlated materials from a numerical renormalization group perspective: How the Fermi-liquid state of SrRuO emerges
Fabian B. Kugler, Manuel Zingl, Hugo U. R. Strand +3
The crossover from fluctuating atomic constituents to a collective state as one lowers temperature or energy is at the heart of the dynamical mean-field theory description of the s…
Magnetic response of SrRuO: quasi-local spin fluctuations due to Hund's coupling
Hugo U. R. Strand, Manuel Zingl, Nils Wentzell +2
We study the magnetic susceptibility in the normal state of SrRuO using dynamical mean-field theory including dynamical vertex corrections. Besides the well known incommens…
High-resolution photoemission on Sr2RuO4 reveals correlation-enhanced effective spin-orbit coupling and dominantly local self-energies
A. Tamai, M. Zingl, E. Rozbicki +17
We explore the interplay of electron-electron correlations and spin-orbit coupling in the model Fermi liquid Sr2RuO4 using laser-based angle-resolved photoemission spectroscopy. Ou…
