Bipolaronic charge density waves and polaronic spin density waves in the Holstein-Hubbard model
At large electron-phonon coupling, the phonon of the Holstein-Hubbard model can be (generally) treated classically. Exact results can be obtained for this model at any band filling and any finite dimension where the Hubbard term with coefficient U is treated rigorously. The existence of chaotic bipolaronic states is proven when U is smaller than a certain value Uc and for an electron-phonon cou...

متن کاملCoupling of spin waves with charge- and spin-density excitations in spin-polarized quantum wells
The coupling of spin waves with chargeand spin-density waves is shown to be induced by a spin-dependent interaction in a quantum well, which is spin polarized by a dc magnetic field at an angle u to the symmetry axis. The mixing of the plasmonic and magnonic modes, which occurs for both intraand intersubband transitions, depends on the coupling constant of the spin-spin interaction, the tilt an...
متن کاملThe microscopic structure of charge density waves in underdoped YBa2Cu3O6.54 revealed by X-ray diffraction.
Charge density wave (CDW) order appears throughout the underdoped high-temperature cuprate superconductors, but the underlying symmetry breaking and the origin of the CDW remain unclear. We use X-ray diffraction to determine the microscopic structure of the CDWs in an archetypical cuprate YBa2Cu3O6.54 at its superconducting transition temperature ∼ 60 K. We find that the CDWs in this material b...
متن کاملA general approach to charge/spin density waves electrodynamics
We reconsider microscopic grounds for the electric field response and for the phase dynamics ofcharge/spin density waves in pure systems. We suggest transparent and free of lengthy calculations way to derive the local Lagrangian valid at any temperature 0 < T < TMF and for arbitrary electronic spectrum provided it supports the existence of
