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.

从坍缩模型看量子经典除法的新见解
我们认为,根据量子理论的坍缩模型解释,量子行为和经典行为之间的基本划分可能类似于热力学相的划分。塌缩参数\((\lambda )\)与塌缩长度尺度(\(r_C\))之间的特定关系在通常的热力学相图中起着共存曲线的作用。我们进一步声称\(\lambda\)和\(r_C\)之间的函数关系得到了现有国际锗实验(IGEX)合作数据的有力支持。在此结果之前,简要讨论了量子测量理论和应用于自由波包动力学的Ghirardi-Rimini-Weber (GRW)模型。

期刊介绍: The conceptual foundations of physics have been under constant revision from the outset, and remain so today. Discussion of foundational issues has always been a major source of progress in science, on a par with empirical knowledge and mathematics. Examples include the debates on the nature of space and time involving Newton and later Einstein; on the nature of heat and of energy; on irreversibility and probability due to Boltzmann; on the nature of matter and observation measurement during the early days of quantum theory; on the meaning of renormalisation, and many others. Today, insightful reflection on the conceptual structure utilised in our efforts to understand the physical world is of particular value, given the serious unsolved problems that are likely to demand, once again, modifications of the grammar of our scientific description of the physical world. The quantum properties of gravity, the nature of measurement in quantum mechanics, the primary source of irreversibility, the role of information in physics – all these are examples of questions about which science is still confused and whose solution may well demand more than skilled mathematics and new experiments. Foundations of Physics is a privileged forum for discussing such foundational issues, open to physicists, cosmologists, philosophers and mathematicians. It is devoted to the conceptual bases of the fundamental theories of physics and cosmology, to their logical, methodological, and philosophical premises. The journal welcomes papers on issues such as the foundations of special and general relativity, quantum theory, classical and quantum field theory, quantum gravity, unified theories, thermodynamics, statistical mechanics, cosmology, and similar.
