Charge Distributions in Polyacetylene Chains Containing a Positively Charged Defect
We present a comparative study of the AIM, CHELPG, GAPT, MK, Mulliken, NPA, and RESP charge distributions associated with a positively charged soliton on increasingly large trans-polyacetylene chains, at HF, MP2, and DFT levels of theory. The charge storage in the soliton-bearing systems is explored in detail, including charge magnitude, charge separation, charge alternation, and chain length e...
متن کاملSpin Conductivity and Spin-Charge Separation in the High Tc Cuprates
We study both the spin and electrical conductivities in models of relevance to the high Tc cuprates. These models describe metallic states with or without spin-charge separation. We demonstrate that, given a linear in temperature dependence of the electrical resistivity, the spin resistivity should also be linear in temperature in the absence of spin-charge separation and under conditions appro...
متن کاملStudies of photoexcited states in polyacetylene and poly(paraphenylenevinylene) by absorption detected magnetic resonance: The case of neutral photoexcitations.
Photoexcited states in trans polyacetylene lt-(CH), l and in ulkoxy derivatives of poly(puraphenylenevinylene) (PPV) have been studied by the technique of absorption detected magnetic resonance. In addition to the stable charged photoexcitations, which are charged solitons in t-(CH), and bipolarons in PPV, we clearly identify neutral photoexcitations with nonzero spins. In t-(CH), these are spi...
متن کاملReal Time Density Functional Simulations of Quantum Scale Conductance
We study electronic conductance through single molecules by subjecting a molecular junction to a time dependent potential and propagating the electronic state in real time using time-dependent density functional theory (TDDFT). This is in contrast with the more common steady-state nonequilibrium Green’s function (NEGF) method. We start by examining quantum scale conductance methods in both the ...
متن کاملSpin-charge separation in two dimensions: A numerical study.
The question of spin-charge separation in two-dimensional lattices has been addressed by numerical simulations of the motion of one hole in a half-filled band. The calculations have been performed on finite clusters with Hubbard and t-J models. By comparing the time evolution of spin and charge polarisation currents in one and two dimensions, evidence in favor of spin-charge separation in two d...
