Preparation and magnetoresistance of Ag 2+x Se thin films deposited via Pulsed Laser Deposition
B. Mogwitz, C. Korte, M. von Kreutzbruck +2
The preparation of Ag 2+x Se thin films with thicknesses between 4 nm and 3000 nm by pulsed laser deposition on single crystalline NaCl and MgO substrates is reported. The films ar…
Magnetism of one-dimensional Wigner lattices and its impact on charge order
M. Daghofer, R. M. Noack, P. Horsch
The magnetic phase diagram of the quarter-filled generalized Wigner lattice with nearest- and next-nearest-neighbor hopping t_1 and t_2 is explored. We find a region at negative t_…
Optical sum rule anomalies in the cuprates: interplay between strong correlation and electronic bandstructures
A. Toschi, M. Capone
We theoretically analyze some of the anomalies of the optical sumrules in the high-temperature superconductors. In particular we address the particularly strong dependence on tempe…
Unidirectional d-wave superconducting domains in the two-dimensional t-J model
Marcin Raczkowski, Manuela Capello, Didier Poilblanc +2
Motivated by the recently observed pattern of unidirectional domains in high-T_c superconductors [Y. Kohsaka et al., Science 315, 1380 (2007)], we investigate the emergence of spon…
Momentum dependence of the electron-phonon coupling and self-energy effects in YBa_2Cu_3O_7 within the local density approximation
Rolf Heid, Klaus-Peter Bohnen, Roland Zeyher +1
Using the local density approximation (LDA) and a realistic phonon spectrum we determine the momentum and frequency dependence of in YBaCuO for the bo…
The Half-Filled One-Dimensional Extended Hubbard Model: Phase diagram and Thermodynamics
S. Glocke, A. Klümper, J. Sirker
We study the thermodynamics of the one-dimensional extended Hubbard model at half-filling using a density-matrix renormalization group method applied to transfer matrices. We show…
