Tuning of the CDW in the Halogen-Bridged Transition-Metal Linear-Chain Compounds
Local-density-approximation calculations are used to show that the metal-metal distance along the chains controls the charge-density wave (CDW) in halogen-bridged transition-metal linear-chain (MX) compounds. The strength of the CDW can be understood in terms of a two band Su-Schrieffer-Heeger model if a hard-core ion-ion repulsion potential is also added. We predict a second-order phase transi...
متن کاملSpin-Peierls transition in TiPO4
The complex interplay between charge, orbital, spin and lattice degrees of freedom in low-dimensional systems with pronounced quantum fluctuations allows for a plethora of complex and unusual ground states. Most of the prominent examples of low-dimensional quantum antiferromagnets with exotic ground states contain Cu (3d, S = 1/2) ions with one hole present in the eg orbitals. Compounds of earl...
متن کاملSolitons, polarons and their dynamics in mixed-valence halogen-bridged MX-chains.
This article describes the photo-generation processes of elementary excitations such as solitons and polarons, and their dynamics in the one-dimensional (1D) halogen-bridged Pt compound [Pt(en)2Br](ClO4)2. Spin-solitons were photo-generated via relaxation processes of CT excitons and self-trapped excitons, made evident by photo-induced absorption and photo-induced electron spin resonance spectr...
متن کاملEffect of quantum lattice fluctuations on the optical-absorption spectra of halogen-bridged mixed-valence transition-metal complexes
The effect of quantum lattice fluctuations on the optical-absorption spectra in the ground state of halogen-bridged mixed-valence transition-metal linear-chain complexes is studied by using a one-dimensional extended Peierls-Hubbard model. The nonadiabatic effects due to finite phonon frequency ωπ > 0 are treated through an energy-dependent electron-phonon scattering function δ(k, k) introduced...
متن کاملThe spin-Peierls chain revisited
We extend previous analytical studies of the ground-state phase diagram of a one-dimensional Heisenberg spin chain coupled to optical phonons, which for increasing spin-lattice coupling undergoes a quantum phase transition from a gap-less to a gaped phase with finite lattice dimerisation. We check the analytical results against established four-block and new two-block density matrix renormalisa...
