Conspectus Organic semiconductors (OSs) are an exciting class of materials that have
enabled disruptive technologies in this century including large-area electronics, flexible …

Coherence refers to correlations in waves. Because matter has a wave-particle nature, it is
unsurprising that coherence has deep connections with the most contemporary issues in …

We present a nonadiabatic classical-trajectory approach that offers the best of both worlds
between fewest-switches surface hopping (FSSH) and quasiclassical mapping dynamics …

In multicomponent quantum chemistry, more than one type of particle is treated quantum
mechanically with either density functional theory or wave function based methods. In …

We recently derived a spin-mapping approach for treating the nonadiabatic dynamics of a
two-level system in a classical environment [JE Runeson and JO Richardson, J. Chem …

Ring polymer surface hopping (RPSH) has been recently introduced as a well-tailored
method for incorporating nuclear quantum effects, such as zero-point energy and tunneling …

Imaginary-time path-integral or 'ring-polymer'methods have been used to simulate quantum
(Boltzmann) statistical properties since the 1980s. This article reviews the more recent …

We propose a trajectory-based method for simulating nonadiabatic dynamics in molecular
systems with two coupled electronic states. Employing a quantum-mechanically exact …

It is well-known that fewest-switches surface hopping (FSSH) fails to correctly capture the
quadratic scaling of rate constants with diabatic coupling in the weak-coupling limit, as …

Electronic friction is a correction to the Born-Oppenheimer approximation, whereby nuclei in
motion experience a drag in the presence of a manifold of electronic states. The notion of …
