First Principles Prediction of Topological Phases in Thin Films of Pyrochlore Iridates
Xiang Hu, Zhicheng Zhong, Gregory A. Fiete
Topological phases have attracted much interest in recent years. While there are a number of three-dimensional materials exhibiting topological properties, there are relatively few…
Fluctuation diagnostics of the electron self-energy: Origin of the pseudogap physics
O. Gunnarsson, T. Schäfer, J. P. F. LeBlanc +5
We demonstrate how to identify which physical processes dominate the low-energy spectral functions of correlated electron systems. We obtain an unambiguous classification through a…
On the separability of dynamical and non-local correlations in three dimensions
T. Schäfer, A. Toschi, Jan M. Tomczak
While second-order phase transitions always cause strong non-local fluctuations, their effect on spectral properties crucially depends on the dimensionality. For the important case…
QSGW+DMFT: an electronic structure scheme for the iron pnictides and beyond
Jan M. Tomczak
While in strongly correlated materials one often focuses on local electronic correlations, the influence of non-local exchange and correlation effects beyond band-theory can be per…
Magnetism of sigma-phase Fe-Mo alloys: its revealing and characterization
J. Cieslak, S. M. Dubiel, M. Reissner
A low-temperature magnetism was revealed in a series of sigma-Fe(100-x)Mo(x) alloys (x=45-53). Its characterization has been done using vibrating sample magnetometry, Mössbauer spe…
Bands, resonances, edge singularities and excitons in core level spectroscopy investigated within the dynamical mean field theory
M. W. Haverkort, G. Sangiovanni, P. Hansmann +3
Using a recently developed impurity solver we exemplify how dynamical mean field theory captures band excitations, resonances, edge singularities and excitons in core level x-ray a…
