Decoherence of Excitons in Multichromophore Systems: Thermal Line Broadening and Destruction of Superradiant Emission
D. J. Heijs, V. A. Malyshev, J. Knoester
We study the temperature-dependent dephasing rate of excitons in chains of chromophores, accounting for scattering on static disorder as well as acoustic phonons in the host matrix…
Thermal broadening of the J-band in disordered linear molecular aggregates: A theoretical study
D. J. Heijs, V. A. Malyshev, J. Knoester
We theoretically study the temperature dependence of the J-band width in disordered linear molecular aggregates, caused by dephasing of the exciton states due to scattering on vibr…
Trapping time statistics and efficiency of transport of optical excitations in dendrimers
Dirk-Jan Heijs, Victor A. Malyshev, Jasper Knoester
We theoretically study the trapping time distribution and the efficiency of the excitation energy transport in dendritic systems. Trapping of excitations, created at the periphery…
Temperature dependent fluorescence in disordered Frenkel chains: interplay of equilibration and local band-edge level structure
M. Bednarz, V. A. Malyshev, J. Knoester
We model the optical dynamics in linear Frenkel exciton systems governed by scattering on static disorder and lattice vibrations, and calculate the temperature dependent fluorescen…
Spin-Isospin Model of NaV_2O_5
M. V. Mostovoy, J. Knoester, D. I. Khomskii
We argue that in the quarter-filled ladder compound NaV_2O_5 the quasi-one-dimensional spin system is strongly coupled to a low-energy antiferroelectric mode of the excitonic type.…
Peierls transition with acoustic phonons and twist deformation in carbon nanotubes
Marc Thilo Figge, Maxim Mostovoy, Jasper Knoester
We consider the Peierls instability due to the interaction of electrons with both acoustic and optical phonons. We suggest that such a transition takes place in carbon nanotubes wi…
