Phase coherence in tight-binding models with nonrandom long-range hopping

- Physics
- 2004

The density of states, even for a perfectly ordered tight-binding model, can exhibit a tail-like feature at the top of the band, provided the hopping integral falls off in space slowly enough. We…

Scaling and universality in the optics of disordered exciton chains.

- PhysicsPhysical review letters

It is demonstrated numerically that the joint probability distribution of exciton energies and transition dipole moments obeys a one-parameter scaling, originating from the fact that both the energy and the dipole moment are determined by the number of coherently bound molecules.

Time-resolved two-dimensional photon-echo spectra of linear J-aggregates containing four molecules per unit cell--a model system for a concentrated water solution of the pseudo-isocyanine dye--is theoretically considered and possibilities of probing quantum coherences, as well as performing quantum control via two-color 2D PE spectroscopy, are discussed.

Unraveling intra-aggregate structural disorder using single-molecule spectroscopy.

A Frenkel exciton model is exploited to show that the experimentally observed correlation of linewidths and other statistical properties of the single-aggregate spectra can be explained from small variations of the molecular orientations within individual aggregates.

Exchange narrowing of the J band of molecular dye aggregates.

A unified theory incorporating the two approaches is presented, which shows that the origins of the narrowing are different and features of both narrowing mechanisms are evident.
