Bridging steady-state and time-domain descriptions of molecular electron transport
Thibaut Lacroix, Namgee Cho, Clemens Vittmann +3
Electron transmission from an input electrode, through a molecular system, to an output electrode has been widely studied using the steady-state non-equilibrium Green's function (N…
Spin-Dependent Momentum Conservation of Electron-Phonon Scattering in Chirality-Induced Spin Selectivity
Clemens Vittmann, James Lim, Dario Tamascelli +2
The elucidation of the mechanisms behind chiral-induced spin selectivity remains an outstanding scientific challenge. Here we consider the role of delocalised phonon modes in elect…
Driving Force and Nonequilibrium Vibronic Dynamics in Charge Separation of Strongly Bound Electron-Hole Pairs
Alejandro D. Somoza, Nicola Lorenzoni, James Lim +2
Electron-hole pairs in organic photovoltaics dissociate efficiently despite their Coulomb-binding energy exceeding thermal energy at room temperature. The electronic states involve…
Interface-Induced Conservation of Momentum Leads to Chiral-Induced Spin Selectivity
Clemens Vittmann, R. Kevin Kessing, James Lim +2
We study the non-equilibrium dynamics of electron transmission from a straight waveguide to a helix with spin-orbit coupling. Transmission is found to be spin-selective and can lea…
Design principles for long-range energy transfer at room temperature
Andrea Mattioni, Felipe Caycedo-Soler, Susana F. Huelga +1
Under physiological conditions, ballistic long-range transfer of electronic excitations in molecular aggregates is generally expected to be suppressed by noise and dissipative proc…
Watching the coherent birth of polaron pairs in conjugated polymers
Antonietta De Sio, Filippo Troiani, Margherita Maiuri +9
Organic semiconductors have the remarkable property that their optical excitation not only generates charge-neutral electron-hole pairs (excitons) but also charge-separated polaron…
