Classical dynamics as constrained quantum dynamics [PDF]

open access: yesJournal of Physics A: Mathematical and General, 2003
We show that the classical mechanics of an algebraic model are implied by its quantizations. An algebraic model is defined, and the corresponding classical and quantum realizations are given in terms of a spectrum generating algebra. Classical equations of motion are then obtained by constraining the quantal dynamics of an algebraic model to an ...

Social group behaviour of triads. Dependence on purpose and gender [PDF]

open access: yes, 2018
We analysed a set of uninstructed pedestrian trajectories automatically tracked in a public area, and we asked a human coder to assess their group relationships.

Dynamical footprints of hurricanes in the tropical dynamics

open access: yesChaos: An Interdisciplinary Journal of Nonlinear Science, 2023
Hurricanes—and more broadly tropical cyclones—are high-impact weather phenomena whose adverse socio-economic and ecosystem impacts affect a considerable part of the global population. Despite our reasonably robust meteorological understanding of tropical cyclones, we still face outstanding challenges for their numerical simulations.

Partial Dynamical Symmetry and Mixed Dynamics [PDF]

open access: yesPhysical Review Letters, 1996
Partial dynamical symmetry describes a situation in which some eigenstates have a symmetry which the quantum Hamiltonian does not share. This property is shown to have a classical analogue in which some tori in phase space are associated with a symmetry which the classical Hamiltonian does not share.

The dynamics of transmission and the dynamics of networks [PDF]

open access: yesJournal of Animal Ecology, 2017
A toy example depicted here highlighting the results of a study in this issue of theJournal of Animal Ecologythat investigates the impact of network dynamics on potential disease outbreaks. Infections (stars) that spread by contact only (left) reduce the predicted outbreak size compared to situations where individuals can become infected by moving ...
