Symplectic Constraints in Quantum Reaction Dynamics: Squeezed-State Suppression and Candidate Width Scales
Stephen Wiggins
Classical reaction dynamics suggests transport through an index-1 saddle is organized not just by flux, but by local symplectic width scales of bounded proxy neighborhoods near the…
Symplectic Constraints in Classical Reaction Dynamics: From Gromov's Camel to Reaction Rates
Stephen Wiggins
We investigate whether ideas from symplectic topology, in particular Gromov's non-squeezing theorem and symplectic capacity, can provide useful geometric insight into classical rea…
Geometric Diagnostics of Scrambling-Related Sensitivity in a Bohmian Preparation Space
Stephen Wiggins
The Out-of-Time-Order Correlator (OTOC) is a standard algebraic diagnostic of quantum information scrambling, but it offers limited direct geometric intuition. In this note, we pro…
Data-Driven Model Identification Using Time Delayed Nonlinear Maps for Systems with Multiple Attractors
Athanasios P. lliopoulos, Evelyn Lunasin, John G. Michopoulos +2
This study presents a method, along with its algorithmic and computational framework implementation, and performance verification for dynamical system identification. The approach…
Barry Carpenter. Pioneering Physical Organic Chemist, Teacher, Mentor and Friend
Stephanie R. Hare, Allan R. Pinhas, Julia Rehbein +2
This is the preface to a special issue of the Journal of Physical Organic Chemistry dedicated to an outstanding physical organic chemist, mentor and friend, Barry Carpenter on the…
Quantifying chaos using Lagrangian descriptors
Malcolm Hillebrand, Sebastian Zimper, Arnold Ngapasare +3
We present and validate simple and efficient methods to estimate the chaoticity of orbits in low dimensional dynamical systems from computations of Lagrangian descriptors (LDs) on…
