Polaron Mobility in the “Beyond Quasiparticles” Regime

Polaron mobility in oxygen-deficient and lithium-doped tungsten trioxide

Electron localization and polaron mobility in oxygen-deficient as well as Li-doped monoclinic tungsten trioxide have been studied in the adiabatic limit in the framework of density functional theory. We show that small polarons formed in the presence of oxygen vacancy prefer the bipolaronic W5+-W5+ configuration, whereas the W6+-W4+ configuration is found to be metastable. Our calculations sugg...

Soliton communication beyond the average-soliton regime

We study semianalytically soliton dynamics in a soliton-based communication line for which the amplifier spacing is larger than the soliton period (referred to as the quasi-adiabatic regime). This regime allows us to overcome the limit on the soliton duration (TFWHM , 15 ps) imposed by the average-soliton regime. Our calculations show that periodically stable propagation of short solitons (TFWH...

Transport through a molecular quantum dot in the polaron crossover regime

Polaron effects and electric field dependence of the charge carrier mobility in conjugated polymers.

Charge transport in conjugated polymers has been investigated using Monte Carlo simulations implemented on top of the Marcus theory for donor-acceptor transition rates. In particular, polaron effects and the dependency of the mobility on the temperature and the applied electric field have been studied. The conclusions are that while the qualitative temperature dependence is similar to that pred...

Managing Mobility in Beyond-3G Environments

Beyond 3G (B3G) environments typically consist of multi-homed terminals and wireless overlay networks. This paper presents a categorization of IP-level mobility management solutions for B3G environments. Closely observing the mobility requirements of a wide range of possible applications, the paper also motivates the consideration of a new mobility management approach in B3G environments, where...
