The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We introduce a stochastic framework based on complex absorbing potentials (CAPs) to investigate exciton transport in large molecular aggregates.

C2weakest assumption

The framework assumes that CAPs can function as non-Hermitian reservoirs and sinks that enable effective measurement of transport efficiency in the simulated exciton dynamics.

C3one line summary

A stochastic framework based on complex absorbing potentials is introduced to simulate exciton transport in molecular aggregates, applied to cyanine dyes to study defect and topology effects with a new packing-based classification scheme.
