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…
Ferrimagnetic mixed-spin ladders in weak and strong coupling limits
D. N. Aristov, M. N. Kiselev
We study two similar spin ladder systems with the ferromagnetic leg coupling. First model includes two sorts of spins, s= 1/2 and s= 1, and the second model comprises only s=1/2 le…
