Nonlinear metastability for a parabolic system of reaction-diffusion equations [PDF]

open access: yes, 2016
We consider a system of reaction-diffusion equations in a bounded interval of the real line, with emphasis on the metastable dynamics, whereby the time-dependent solution approaches its steady state in an asymptotically exponentially long time interval ...

Population–reaction model and microbial experimental ecosystems for understanding hierarchical dynamics of ecosystems [PDF]

open access: yes, 2016
Understanding ecosystem dynamics is crucial as contemporary human societies face ecosystem degradation. One of the challenges that needs to be recognized is the complex hierarchical dynamics.

Simulation of weak polyelectrolytes: A comparison between the constant pH and the reaction ensemble method

open access: yes, 2017
The reaction ensemble and the constant pH method are well-known chemical equilibrium approaches to simulate protonation and deprotonation reactions in classical molecular dynamics and Monte Carlo simulations.

First-principles quantum dynamical theory for the dissociative chemisorption of H2O on rigid Cu(111)

open access: yesNature Communications, 2016
Dissociative chemisorption dynamics of polyatomic molecules on surfaces are still challenging to probe quantitatively. Here, the authors report the 9-dimensional quantum dynamics of H2O dissociative chemisorption on Cu(111), with the highest level of ...

Reversible Interacting-Particle Reaction Dynamics [PDF]

open access: yesThe Journal of Physical Chemistry B, 2018
Interacting-Particle Reaction Dynamics (iPRD) simulates the spatiotemporal evolution of particles that experience interaction forces and can react with one another. The combination of interaction forces and reactions enable a wide range of complex reactive systems in biology and chemistry, but give rise to new questions such as how to evolve the ...

Phase reduction approach to synchronization of spatiotemporal rhythms in reaction-diffusion systems

open access: yes, 2014
Reaction-diffusion systems can describe a wide class of rhythmic spatiotemporal patterns observed in chemical and biological systems, such as circulating pulses on a ring, oscillating spots, target waves, and rotating spirals. These rhythmic dynamics can

Observation of triplet-assisted long-distance charge-transfer exciton transport in single organic cocrystal

open access: yesNature Communications
Charge-transfer (CT) states with long transport distances are highly desired for promoting the performance of organic optoelectronic devices in photoconversion and electroluminescence.

Four-Atom Reaction Dynamics

open access: yesThe Journal of Physical Chemistry, 1994
It is now possible to do quantum reactive scattering calculations on the state-to-state dynamics of gas phase chemical reactions involving four atoms. This article gives an overview of this recent progress. A survey is also given of results obtained using the rotating bond approximation (RBA).

Coherent chemical kinetics as quantum walks II: Radical-pair reactions in Arabidopsis thaliana

open access: yes, 2015
We apply the quantum-walk approach recently proposed in arXiv:quant-ph-1506.04213 to a radical-pair reaction where realistic estimates for the intermediate transition rates are available.

High Order Split Operators for the Time-Dependent Wavepacket method of Triatomic Reactive Scattering in Hyperspherical Coordinates

open access: yesEntropy, 2019
Since the introduction of a series of methods for solving the time-dependent Schrödinger equation (TDSE) in the 80s of the last centry, such as the Fourier transform, the split operator (SO), the Chebyshev polynomial propagator, and complex ...
