Dispersion of incoherent spectral features in systems with strong electron-phonon coupling

O. Rösch, O. Gunnarsson

We study (inverse) photoemission from systems with strong coupling of doped carriers to phonons. Using an adiabatic approximation, we develop a method for calculating spectra. This…

Electron-phonon interaction in the three-band model

O. Rösch, O. Gunnarsson

We study the half-breathing phonon in the three-band model of a high temperature superconductor, allowing for vibrations of atoms and resulting changes of hopping parameters. Two d…

The Hall conductivity in unconventional charge density wave systems

D. N. Aristov, R. Zeyher

Charge density waves with unconventional order parameters, for instance, with d-wave symmetry (DDW), may be relevant in the underdoped regime of high-T_c cuprates or other quasi-on…

Functional renormalization group for Luttinger liquids with impurities

S. Andergassen, T. Enss, V. Meden +3

We improve the recently developed functional renormalization group (fRG) for impurities and boundaries in Luttinger liquids by including renormalization of the two-particle interac…

Theory of optical spectral weights in Mott insulators with orbital degrees of freedom

Giniyat Khaliullin, Peter Horsch, Andrzej M. Oles

Introducing partial sum rules for the optical multiplet transitions, we outline a unified approach to magnetic and optical properties of strongly correlated transition metal oxides…

Probing the phase diagram of CeRu_2Ge_2 by thermopower at high pressure

H. Wilhelm, D. Jaccard

The temperature dependence of the thermoelectric power, S(T), and the electrical resistivity of the magnetically ordered CeRu_2Ge_2 (T_N=8.55 K and T_C=7.40 K) were measured for pr…
