Magnetic incommensurability and fluctuating charge density waves in the repulsive Hubbard model
A Sherman, M Schreiber
Magnetic and charge susceptibilities of the two-dimensional repulsive Hubbard model are investigated applying a strong coupling diagram technique in which the expansion in powers o…
The chemical potential for the inhomogeneous electron liquid in terms of its kinetic and potential parts with special consideration of the surface pote ntial step and BCS-BEC crossover
K. Morawetz, N. H. March, R. H. Squire
The chemical potential of a many-body system is valuable since it carries fingerprints of phase changes. Here, we summarize results for for a thre e-dimensional electron li…
Are the renormalized band widths in TTF-TCNQ of structural or electronic origin? - An angular dependent NEXAFS study
M. Sing, J. Meyer, M. Hoinkis +5
We have performed angle-dependent near-edge x-ray absorption fine structure measurements in the Auger electron yield mode on the correlated quasi-one-dimensional organic conductor…
Magnetic susceptibility of the two-dimensional Hubbard model using a power series for the hopping constant
Alexei Sherman, Michael Schreiber
The magnetic susceptibility of the two-dimensional repulsive Hubbard model with nearest-neighbor hopping is investigated using the diagram technique developed for the case of stron…
