1. Wavefunction

   Linked via "environment"

   Large Mass/Energy: When the system's mass or energy scale becomes much larger than $\hbar$.
   Decoherence: The interaction of the quantum system with its environment causes the off-diagonal elements of the density matrix to decay rapidly, effectively mimicking wavefunction collapse without explicit measurement.
   The fundamental difference in state description is summarized below, reflecting how the wavefunction fundamentally alters the concept of object identity [6].
