RT Journal Article SR Electronic T1 Modeling multi-particle complexes in stochastic chemical systems JF bioRxiv FD Cold Spring Harbor Laboratory SP 045435 DO 10.1101/045435 A1 Muir J. Morrison A1 Justin B. Kinney YR 2016 UL http://biorxiv.org/content/early/2016/03/23/045435.abstract AB Large complexes of classical particles play central roles in biology, in polymer physics, and in other disciplines. However, physics currently lacks mathematical methods for describing such complexes in terms of component particles, interaction energies, and assembly rules. Here we describe a Fock space structure that addresses this need, as well as diagrammatic methods that facilitate the use of this formalism. These methods can dramatically simplify the equations governing both equilibrium and non-equilibrium stochastic chemical systems. A mathematical relationship between the set of all complexes and a list of rules for complex assembly is also identified.
