  We present CHAMPION: a software developed to automatically detect
time-dependent bonds between atoms based on their dynamics, classify the local
graph topology around them, and analyze the physicochemical properties of these
topologies by statistical physics. In stark contrast to methodologies where
bonds are detected based on static conditions such as cut-off distances,
CHAMPION considers pairs of atoms to be bound only if they move together and
act as a bound pair over time. Furthermore, the time-dependent global bond
graph is possible to split into dynamically shifting connected components or
subgraphs around a certain chemical motif and thereby allow the physicochemical
properties of each such topology to be analyzed by statistical physics.
Applicable to condensed matter and liquids in general, and electrolytes in
particular, this allows both quantitative and qualitative descriptions of local
structure, as well as dynamical processes such as speciation and diffusion. We
present here a detailed overview of CHAMPION, including its underlying
methodology, implementation and capabilities.
