Non-Stationary Critical Phenomena: Expanding The Critical Point
Richard E. Spinney, Richard G. Morris
A prototypical model of symmetry-broken active matter -- biased quorum-sensing active particles (bQSAPs) -- is used to extend notions of dynamic critical phenomena to the paradigma…
A Dean-Kawasaki equation for reaction diffusion systems driven by Poisson noise
Richard E. Spinney, Richard G. Morris
We derive a stochastic partial differential equation that describes the fluctuating behaviour of reaction-diffusion systems of N particles, undergoing Markovian, unary reactions. T…
Bivalent Kinetics: Insights from Many Body Physics
Richard E. Spinney, Lawrence K. Lee, Richard G. Morris
Bivalency confers several concentration-dependent phenomena, including avidity, competitive exchange and multi-site competitive exchange. Since these concepts are crucial for a wid…
Thermodynamics of emergent structure in active matter
Emanuele Crosato, Mikhail Prokopenko, Richard E. Spinney
Active matter is rapidly becoming a key paradigm of out-of-equilibrium soft matter exhibiting complex collective phenomena, yet the thermodynamics of such systems remain poorly und…
A thermodynamically consistent model of finite state machines
Dominique Chu, Richard Spinney
Finite state machines (FSMs) are a theoretically and practically important model of computation. We propose a general, thermodynamically consistent model of FSMs and characterise t…
Entropy balance and Information processing in bipartite and non-bipartite composite systems
Richard E. Spinney, Joseph T. Lizier, Mikhail Prokopenko
Information dynamics is an emerging description of information processing in complex systems which describes systems in terms of intrinsic computation, identifying computational pr…
Information ratchets exploiting spatially structured information reservoirs
Richard E. Spinney, Mikhail Prokopenko, Dominique Chu
Information ratchets extract work from heat baths using low entropy information reservoirs. We find that the structure of the reservoirs affects both their performance and phase di…
Entropy production from stochastic dynamics in discrete full phase space
Ian J. Ford, Richard E. Spinney
The stochastic entropy generated during the evolution of a system interacting with an environment may be separated into three components, but only two of these have a non-negative…
Entropy production in full phase space for continuous stochastic dynamics
Richard E. Spinney, Ian J. Ford
The total entropy production and its three constituent components are described both as fluctuating trajectory-dependent quantities and as averaged contributions in the context of…
Non-equilibrium thermodynamics of stochastic systems with odd and even variables
Richard E. Spinney, Ian J. Ford
The total entropy production of stochastic systems can be divided into three quantities. The first corresponds to the excess heat, whilst the second two comprise the house-keeping…
Fluctuation relations: a pedagogical overview
Richard E. Spinney, Ian J. Ford
The fluctuation relations have received considerable attention since their emergence and development in the 1990s. We present a summary of the main results and suggest ways to inte…
