The population transfer dynamics of model donor–bridge–acceptor systems is studied by comparing a recently developed polaron-transformed quantum master equation (PQME) with the well-known Redfield and Förster theories of quantum transport. We show that the PQME approach reduces to these two theories in their respective limits of validity and naturally interpolates between them as a function of the system–bath coupling strength. By exploring the parameter space of our model problem, we identify…

Influence of Coherent Tunneling and Incoherent Hopping on the Charge Transfer Mechanism in Linear Donor-Bridge-Acceptor Systems.

The quantum master equation (QME) approach is applied, based on second-order perturbation theory in a quantum dissipative system, to examine the dynamical processes involved in charge-transfer and follow the population transfer rate at the acceptor to shed light on the transition from tunneling to hopping.

Accurate information on the distance dependence of resonance energy transfer (RET) is crucial for its utilization as a spectroscopic ruler of nanometer scale distances. In this regard, understanding

Interplay of Direct and Indirect Charge-Transfer Pathways in Donor-Bridge-Acceptor Systems.

It is demonstrated that the combination of indirect and direct donor-acceptor coupling either enhances or leads to a destructive quantum interference effect on charge-transport processes, depending on the energy landscape of the DBA system.

Studying rare nonadiabatic dynamics with transition path sampling quantum jump trajectories.

A method to study rare nonadiabatic dynamics in open quantum systems using transition path sampling and quantum jump trajectories using the stochastic realizations of an unravelled quantum master equation, which results in trajectories that can be conditioned on starting and ending in particular quantum states.

Theoretical investigation of non-Förster exciton transfer mechanisms in perylene diimide donor, phenylene bridge, and terrylene diimide acceptor systems.

Results confirm that the delocalization of the exciton to the bridge parts contributes to significant enhancement of donor-acceptor electronic coupling and suggest that the contribution of common vibrational modes serves as the main source of deviation from Förster's spectral overlap expression.

Analysis of the Trajectory Surface Hopping Method from the Markov State Model Perspective

This work addresses the known deficiency of the FSSH method to describe quantum transitions between electronic states that are not coupled directly, in the processes such as Auger recombination by introducing an alternative definition for the surface hopping probabilities, as derived from the Markov state model perspective.

Spin-selective electron transfer reactions of radical pairs: Beyond the Haberkorn master equation.

By performing simulations of radical pair reactions with the exact hierarchical equations of motion method, it is demonstrated that the master equations provide a very accurate description of radical pairs undergoing spin-selective non-adiabatic electron transfer reactions.

Computational modeling of charge hopping dynamics along a disordered one-dimensional wire with energy gradients in quantum environments.

Results show that the charge transport in the quantum bath is more sensitive to the magnitude of the gradient and the disorder than in the classical bath, and among all the four approximations for the hopping rates, the SPI approximation is confirmed to work best overall.

Spin Dynamics in Radical Pairs

The coherent spin dynamics of radical pairs play a crucial role in their reactions, which consequently cannot be described by a simple kinetic scheme. Instead, simulations of the spin dynamics are

This work extends previous work on singlet exciton fission in isolated dimers to the case of crystalline materials, focusing on pentacene as a canonical and concrete example, demonstrating significant charge-transfer character in the low-lying excited states.



Consistent treatment of coherent and incoherent energy transfer dynamics using a variational master equation.

This work investigates the energy transfer dynamics in a donor-acceptor model by developing a time-local master equation technique based on a variational transformation of the underlying Hamiltonian, and shows how to include the effects of both environmental correlations and non-equilibrium preparations within the formalism.

Crossover from Single-Step Tunneling to Multistep Hopping for Molecular Triplet Energy Transfer

It is shown that the dominant TT mechanism switches from tunneling to wire-like hopping between bridge lengths 1 and 2, and the crossover observed for TT can be determined by direct observation of the bridge-occupied state.

An ultrafast polarization experiment specifically designed to observe quantum coherent dynamics in the intermediate coupling regime for electronic energy transfer suggests that quantum transport effects occur at room temperature when chemical donor-acceptor bonds help to correlate dephasing perturbations.

Theory of coherent resonance energy transfer for coherent initial condition.

It is shown that contribution of inhomogeneous terms is more significant for coherent initial condition than for localized one and the overall model calculations provide details of the interplay between quantum coherence and nonequilibrium/non-Markovian effects in the time dependent donor population dynamics.
