We study the effect of temporal correlation in a Langevin equation describing nonadiabatic dynamics at metal surfaces. For a harmonic oscillator, the Langevin equation preserves the quantum dynamics exactly and it is demonstrated that memory effects are needed in order to conserve the ground state energy of the oscillator. We then compare the result of Langevin dynamics in a harmonic potential with a perturbative master equation approach and show that the Langevin equation gives a better…

Reaction-Induced Excitations and Their Effect on Surface Chemistry
Despite intensive study of reactions on metals, it is unclear whether electronic excitations play an important role. Here, we show that nonadiabatic effects do indeed play a significant role in N2…
Hot electron effects during reactive scattering of H2 from Ag(111): assessing the sensitivity to initial conditions, coupling magnitude, and electronic temperature.
TLDR
This work systematically studies the effect of hot electrons on measurable state-to-state scattering probabilities of molecular hydrogen from a (111) surface of silver and assesses the ability of ab initio electronic friction methods to accurately describe hot electron-mediated energy loss as a function of initial reaction conditions and electronic temperature.

Quantum corrected Langevin dynamics for adsorbates on metal surfaces interacting with hot electrons.
TLDR
It is shown how to rigorously obtain quantum mechanical probabilities from the classical phase space distributions resulting from the dynamics of Langevin dynamics for quadratic potentials and adsorbates interacting with a thermal reservoir of electrons.
A Langevin equation approach to electron transfer reactions in the diabatic basis.
TLDR
The two-hop Langevin equation (THLE) appears to provide a viable alternative to established methods--such as Ehrenfest dynamics or surface hopping--for the treatment of nonadiabatic effects in electron transfer simulations.
Reactive and nonreactive scattering of N2 from Ru(0001): a six-dimensional adiabatic study.
TLDR
The theoretical results show a strong dependence of reaction on the initial vibrational state and computed angular scattering distributions and parallel translation energy distributions are in good agreement with experiments on scattering, but the theory overestimates vibrational and rotational excitations in scattering.
Nonadiabatic effects in the dissociation of oxygen molecules at the Al(111) surface
The measured low initial sticking probability of oxygen molecules at the Al(111) surface that had puzzled the field for many years was recently explained in a nonadiabatic picture invoking…
Quantum kinetic theory of vibrational heating and bond breaking by hot electrons
A quantum kinetic theory of surface bond-breaking induced by laser-excited hot electrons is presented within a vibrational-heating mechanism, in which the fast electron-vibration energy transfer…
Femtosecond laser induced associative desorption of H2 from Ru(0001): comparison of "first principles" theory with experiment.
TLDR
It is shown that the success of the one dimensional model is based on the rapid intermixing of the z and d coordinates as the H-H climbs out of the adsorption well, which implies that some caution must be used in interpreting activation energies obtained in fitting experiments to the one dimension model.
Indirect evidence for strong nonadiabatic coupling in N2 associative desorption from and dissociative adsorption on Ru(0001)
This paper reports the simultaneous internal state and translational energy resolved associative desorption flux of N2 from Ru(0001) using two different experimental approaches. Both experiments show…
How adiabatic is activated adsorption/associative desorption?
TLDR
Using density-functional theory, friction coefficients describing the damping of nuclear motion into electron-hole pair excitation for the two best-known examples of activated adsorption are calculated and found that nonadiabatic effects are minimal for the H2/Cu(111) system, but are quite important for N2/Ru(0001).
Origin of power laws for reactions at metal surfaces mediated by hot electrons.
TLDR
A model of multiple inelastic scattering by hot electrons is proposed which reproduces this power law and the observed exponents of several experiments and a simple physical interpretation of the exponent n, which represents the number of adsorbate vibrational states participating in the reaction.
