Incommensurate magnetic order: A fingerprint for electronic correlations in hole-doped cuprates
Michael Klett, Jacob Beyer, David Riegler +4
Intertwined charge and magnetic fluctuations in high- copper oxide superconductors (cuprates) are hypothesized to be a consequence of their correlated electronic nature…
Selection of direction of the ordered moments in NaIrO and RuCl
Yuriy Sizyuk, Peter Woelfle, Natalia B. Perkins
The magnetic orders in NaIrO and RuCl, honeycomb systems with strong spin-orbit coupling and correlations, have been recently described by models with the dominant…
The free energy of anisotropic quantum spin systems: Functional integral representation
Peter Woelfle, Natalia B Perkins, Yuriy Sizyuk
In this work, we propose a method for calculating the free energy of anisotropic quantum spin systems. We use the Hubbard-Stratonovich transformation to express the partition funct…
Spin-flip scattering of critical quasiparticles and the phase diagram of YbRh2Si2
Peter Woelfle, Elihu Abrahams
Several observed transport and thermodynamic properties of the heavy-fermion compound YbRh2Si2 in the quantum critical regime are unusual and suggest that the fermionic quasipartic…
Interplay of many-body and single-particle interactions in iridates and rhodates
Natalia B. Perkins, Yuriy Sizyuk, Peter Wölfle
Motivated by recent experiments exploring the spin-orbit-coupled magnetism in - and -band transition metal oxides, we study magnetic interactions in Ir- and Rh-based compou…
Quasiparticles beyond the Fermi liquid and heavy fermion criticality
Peter Wölfle, Elihu Abrahams
We give a self-consistent theory of the scale dependent effective mass enhancement m*/m of quasiparticles by 3D antiferromagnetic (AFM) spin fluctuations in the presence of disorde…
Nonequilibrium Cotunneling through a Three-Level Quantum Dot
S. Schmaus, V. Koerting, J. Paaske +3
We calculate the nonlinear cotunneling conductance through a quantum dot with 3 electrons occupying the three highest lying energy levels. Starting from a 3-orbital Anderson model,…
