We investigate geometric phase (GP) effects in nonadiabatic transitions through a conical intersection (CI) in an N-dimensional linear vibronic coupling (ND-LVC) model. This model allows for the coordinate transformation encompassing all nonadiabatic effects within a two-dimensional (2D) subsystem, while the other N - 2 dimensions form a system of uncoupled harmonic oscillators identical for both electronic states and coupled bi-linearly with the subsystem coordinates. The 2D subsystem governs…

The results reported here represent the first fully non-adiabatic quantum reactive scattering calculation for an ultracold reaction and validate the importance of the geometric phase on the Wigner threshold behavior.

Geometric Phase Effects in Ultracold Chemical Reactions

The role of the geometric phase effect in chemical reaction dynamics has long been a topic of active experimental and theoretical investigations. The topic has received renewed interest in recent

The moving crude adiabatic alternative to the adiabatic representation in excited state dynamics

The choice of the electronic representation in on-the-fly quantum dynamics is crucial. The adiabatic representation is appealing since adiabatic states are readily available from quantum chemistry

Nonadiabatic Quantum Dynamics with Frozen-Width Gaussians.

Techniques for simulating fully quantum nonadiabatic dynamics using the frozen-width moving Gaussian basis functions to represent the nuclear wave function are reviewed and the Nonstochastic Open System Schrödinger Equation is considered.

Geometric phase effects in low-energy dynamics near conical intersections: a study of the multidimensional linear vibronic coupling model.

In molecular systems containing conical intersections, a nontrivial geometric phase (GP) appears in the nuclear and electronic wave functions in the adiabatic representation of an N-dimensional linear vibronic coupling model.

When do we need to account for the geometric phase in excited state dynamics?

Using examples of the bis(methylene) adamantyl and butatriene cations and the pyrazine molecule, it is demonstrated that their effective 2D models reproduce the short-time dynamics of the corresponding full dimensional models, and the introduced indicators are very reliable in assessing GP effects.

Why Do Mixed Quantum-Classical Methods Describe Short-Time Dynamics through Conical Intersections So Well? Analysis of Geometric Phase Effects.

Using two-dimensional linear vibronic coupling models, this work unravels how the MQC methods can effectively mimic the most significant dynamical GP effects: compensation for repulsive diagonal second-order nonadiabatic couplings and transfer enhancement for a fully cylindrically symmetric component of a nuclear distribution.

Effect of the geometric phase on nuclear dynamics at a conical intersection: Extension of a recent topological approach from one to two coupled surfaces.

The approach is exact, and uses simple topology to separate the wave function into contributions from Feynman paths that wind different numbers of times, and in different senses, around the conical intersection.

Nonequilibrium Fermi golden rule for electronic transitions through conical intersections.

A simple analytical expression for the time evolution of electronic populations at finite temperature is developed, which can be seen as a nonequilibrium generalization of the Fermi golden rule due to aNonequilibrium character of the initial photoinduced nuclear distribution.
