decoherencelike

decoherencelike refers to phenomena or processes that exhibit characteristics similar to quantum decoherence, but occur in systems that are not quantum mechanical in nature. Quantum decoherence is the loss of quantum coherence in a system due to interaction with its environment. This interaction causes a quantum system to transition from a superposition of states to a classical mixture of states.

In a decoherencelike process, a system that might otherwise exhibit complex, correlated, or seemingly non-classical behavior becomes simplified, more predictable, or loses its interconnectedness due to external influences or interactions. This simplification can manifest as a loss of correlations, a reduction in the range of possible states, or a transition to a more classical-like description of behavior.

For instance, in certain complex classical systems, interactions with a surrounding medium or a multitude of internal random processes can lead to a similar "washing out" of initial sensitive dependencies or intricate patterns, analogous to how an environment destroys quantum superposition. While not involving quantum states or wave functions, the outcome shares a functional resemblance: the system's behavior becomes less dependent on its precise initial quantum state and more on probabilistic, classical outcomes. This concept is often used metaphorically or as an analogy to understand complex classical systems or to draw parallels between quantum and classical physics when discussing the emergence of classicality.
