Lagrangian Descriptors of Thermalized Transition States on Time-Varying Energy Surfaces.
Thermalized chemical reactions driven under dynamical load are characteristic of activated dynamics for arbitrary nonautonomous systems. Recent generalizations of transition state theory to obtainExpand

Ab initio calculation of anharmonic constants for a transition state, with application to semiclassical transition state tunneling probabilities
“Good” (i.e. conserved) action variables exist in the vicinity of a saddle point (i.e. transition state) of a potential energy surface in complete analogy to those related to a minimum on theExpand

Mechanism for radical cation transport in duplex DNA oligonucleotides.
We investigated the photoinduced one-electron oxidation of a series of DNA oligomers having a covalently linked anthraquinone group (AQ) and containing [(A)(n)GG](m) or [(T)(n)GG](m) segments. TheseExpand

Cumulative reaction probabilities for H+H2→H2+H from a knowledge of the anharmonic force field
Abstract In an earlier publication, the authors showed how knowledge of a quartic force field expanded about a transition state can be used to obtain transition state theory tunneling probabilities.Expand

Chemical dynamics between wells across a time-dependent barrier: Self-similarity in the Lagrangian descriptor and reactive basins.
In chemical or physical reaction dynamics, it is essential to distinguish precisely between reactants and products for all times. Expand

Chemical reaction dynamics with stochastic potentials below the high-friction limit
Thermally activated escape over a fluctuating barrier is studied by numerical simulations of the Langevin equation. A class of merged harmonic oscillator potentials are used to model barrierExpand

Semiclassical transition state theory. A new perspective
Abstract The semiclassical transition state theory (SCTST) introduced by Miller, Hernandez, Handy, Jayatilaka and Willetts requires the inversion of an (effectively integrable ) Hamiltonian withExpand

Adaptive Steered Molecular Dynamics of the Long-Distance Unfolding of Neuropeptide Y.
Neuropeptide Y (NPY) has been found to adopt two stable conformations in vivo: (1) a monomeric form called the PP-fold in which a polyproline tail is folded onto an α-helix via a β-turn and (2) aExpand

Quantum time correlation functions and classical coherence
Abstract Quantum time correlation functions for electronically adiabatic and nonadiabatic processes have recently been evaluated directly using the semiclassical initial value representation [J. CaoExpand

Dynamical simulation of dipolar Janus colloids: equilibrium structure and thermodynamics.
The static microstructures and thermodynamics of a colloidal dispersion of dipolar Janus (DJ) particles-that is, dipolar spheres in which each hemisphere is specified by a different chargeExpand
