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…
Optical conductivity and the sum rule in the DDW state
D. N. Aristov, R. Zeyher
The density-wave with d-wave order parameter (DDW) is possibly realized in the underdoped regime of high-T_c cuprates. The DDW state is characterized by two branches of low-lying e…
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…
Renormalization of the electron-phonon coupling in the one-band Hubbard model
Erik Koch, Roland Zeyher
We investigate the effect of electronic correlations on the coupling of electrons to Holstein phonons in the one-band Hubbard model. We calculate the static electron-phonon vertex…
