Incommensurate Magnetism in FeAs Strips: Neutron Scattering from CaFeAs
Yusuke Nambu, Liang L. Zhao, Emilia Morosan +7
Magnetism in the orthorhombic metal CaFeAs was examined through neutron diffraction for powder and single crystalline samples. Incommensurate (${\bm q}_{\rm m}\approx (0.37…
Local suppression of the hidden order phase by impurities in URu2Si2
Maria E. Pezzoli, Matthias J. Graf, Kristjan Haule +2
We consider the effects of impurities on the enigmatic hidden order (HO) state of the heavy-fermion material URu2Si2. In particular, we focus on local effects of Rh impurities as a…
The coherence-incoherence crossover and the mass-renormalization puzzles in Sr2RuO4
Jernej Mravlje, Markus Aichhorn, Takashi Miyake +3
We calculate the electronic structure of Sr2RuO4, treating correlations in the framework of dynamical mean-field theory. The approach successfully reproduces several experimental r…
Dynamical Mean-Field Theory for Molecular Electronics: Electronic Structure and Transport Properties
D. Jacob, K. Haule, G. Kotliar
We present an approach for calculating the electronic structure and transport properties of nanoscopic conductors that takes into account the dynamical correlations of strongly int…
Magnetization, Maxwell's Relations and the Local Physics of the Dilute System Th_{1-x}U_{x}Ru_{2}Si_{2}
Anna Toth, Premala Chandra, Piers Coleman +2
The dilute Kondo compound, Th_{1-x}U_{x}Ru_{2}Si_{2} (TURS), displays non-Fermi liquid behavior but no zero-point entropy; it thus appears to elude description by known single-ion…
Magnetism and Charge Dynamics in Iron Pnictides
Z. P. Yin, K. Haule, G. Kotliar
In a wide variety of materials, such as copper oxides, heavy fermions, organic salts, and the recently discovered iron pnictides, superconductivity is found in close proximity to a…
