Molecular theory of Langevin dynamics for active self-diffusiophoretic colloids
Bryan Robertson, Jeremy Schofield, Pierre Gaspard +1
Active colloidal particles that are propelled by a self-diffusiophoretic mechanism are often described by Langevin equations that are either postulated on physical grounds or deriv…
The stochastic motion of self-thermophoretic Janus particles
Pierre Gaspard, Raymond Kapral
Langevin equations for the self-thermophoretic dynamics of Janus motors partially coated with an absorbing layer that is heated by a radiation field are presented. The derivation o…
Thermodynamics and statistical mechanics of chemically-powered synthetic nanomotors
Pierre Gaspard, Raymond Kapral
Colloidal motors without moving parts can be propelled by self-diffusiophoresis, coupling molecular concentration gradients generated by surface chemical reactions to the velocity…
Finite-time fluctuation theorem for diffusion-influenced surface reactions on spherical and Janus catalytic particles
Pierre Gaspard, Patrick Grosfils, Mu-Jie Huang +1
A finite-time fluctuation theorem for the diffusion-influenced surface reaction A <=> B is investigated for spherical and Janus catalytic particles. The finite-time rates and therm…
Finite-time fluctuation theorem for diffusion-influenced surface reactions
Pierre Gaspard, Raymond Kapral
A finite-time fluctuation theorem is proved for the diffusion-influenced surface reaction A<->B in a domain with any geometry where the species A and B undergo diffusive transport…
Fluctuating chemohydrodynamics and the stochastic motion of self-diffusiophoretic particles
Pierre Gaspard, Raymond Kapral
The propulsion of active particles by self-diffusiophoresis is driven by asymmetric catalytic reactions on the particle surface that generate a mechanochemical coupling between the…
Mechanochemical fluctuation theorem and thermodynamics of self-phoretic motors
Pierre Gaspard, Raymond Kapral
Microscopic dynamical aspects of the propulsion of nanomotors by self-phoretic mechanisms are considered. Propulsion by self-diffusiophoresis relies on the mechanochemical coupling…
Self-propulsion through symmetry breaking
Pierre de Buyl, Alexander S. Mikhailov, Raymond Kapral
In addition to self-propulsion by phoretic mechanisms that arises from an asymmetric distribution of reactive species around a catalytic motor, spherical particles with a uniform d…
Surface-hopping dynamics and decoherence with quantum equilibrium structure
Robbie Grunwald, Hyojoon Kim, Raymond Kapral
In open quantum systems decoherence occurs through interaction of a quantum subsystem with its environment. The computation of expectation values requires a knowledge of the quantu…
Decoherence and Quantum-Classical Master Equation Dynamics
Robbie Grunwald, Raymond Kapral
The conditions under which quantum-classical Liouville dynamics may be reduced to a master equation are investigated. Systems that can be partitioned into a quantum-classical subsy…
Quantum-Classical Limit of Quantum Correlation Functions
Alessandro Sergi, Raymond Kapral
A quantum-classical limit of the canonical equilibrium time correlation function for a quantum system is derived. The quantum-classical limit for the dynamics is obtained for quant…
Rapid convergence of time-averaged frequency in phase synchronized systems
Jörn Davidsen, István Z. Kiss, John L. Hudson +1
Numerical and experimental evidence is presented to show that many phase synchronized systems of non-identical chaotic oscillators, where the chaotic state is reached through a per…
Phase synchronization and topological defects in inhomogeneous media
J. Davidsen, R. Kapral
The influence of topological defects on phase synchronization and phase coherence in two-dimensional arrays of locally-coupled, nonidentical, chaotic oscillators is investigated. T…
Fluctuation Effects on Quadratic Autocatalysis Fronts
Mikhail V. Velikanov, Raymond Kapral
A Markov chain model for spatially distributed autocatalytic systems with a quadratic reaction rate is considered. An approximate solution for the local probability distribution is…
