Magnetic order in the pseudogap phase of high- superconductors
B. Fauque, Y. Sidis, V. Hinkov +4
One of the leading issues in high- superconductors is the origin of the pseudogap phase in underdoped cuprates. Using polarized elastic neutron diffraction, we identify a nove…
Kondo physics in transport through a quantum dot with Luttinger liquid leads
S. Andergassen, T. Enss, V. Meden
We study the gate voltage dependence of the linear conductance through a quantum dot coupled to one-dimensional leads. For interacting dot electrons but noninteracting leads Kondo…
Renormalization-group analysis of the one-dimensional extended Hubbard model with a single impurity
S. Andergassen, T. Enss, V. Meden +3
We analyze the one-dimensional extended Hubbard model with a single static impurity by using a computational technique based on the functional renormalization group. This extends p…
Momentum-resolved spectral functions of SrVO calculated by LDA+DMFT
I. A. Nekrasov, K. Held, G. Keller +6
LDA+DMFT, the merger of density functional theory in the local density approximation and dynamical mean-field theory, has been mostly employed to calculate k-integrated spectra acc…
Polaronic behavior of undoped high-Tc cuprates
O. Rösch, O. Gunnarsson, X. J. Zhou +6
We present angle-resolved photoemission spectroscopy (ARPES) data on undoped La2CuO4, indicating polaronic coupling between bosons and charge carriers. Using a shell model, we calc…
Optical conductivity of unconventional charge density wave systems: Role of vertex corrections
D. N. Aristov, R. Zeyher
The optical conductivity of a d-CDW conductor is calculated for electrons on a square lattice and a nearest-neighbor charge-charge interaction using the lowest-order conserving app…
