Abstract

We argue, in light of Collapse Model interpretation of quantum theory, that the fundamental division between the quantum and classical behaviors might be analogous to the division of thermodynamic phases. A specific relationship between the collapse parameter \((\lambda )\) and the collapse length scale (\(r_C\)) plays the role of the coexistence curve in usual thermodynamic phase diagrams. We further claim that our functional relationship between \(\lambda\) and \(r_C\) is strongly supported by the existing International Germanium Experiment (IGEX) collaboration data. This result is preceded by a brief discussion of quantum measurement theory and the Ghirardi–Rimini–Weber (GRW) model applied to the free wavepacket dynamics.
