Quantum mechanics as an approximation of classical statistical mechanics | | Andrei Khrennikov
; | | Date: |
3 Jun 2005 | | Subject: | Statistical Mechanics | cond-mat.stat-mech | | Abstract: | We show that the probabilistic formalism of QM can be obtained as a special projection of classical statistical mechanics for systems with an infinite number of degrees of freedom. Such systems can be interpreted as classical fields. Thus in our approach QM is a projection of (prequantum) classical statistical field theory (PCSFT). This projection is based on the Taylor expansion of classical physical variables -- maps $f: Omega o {f R},$ where $Omega$ is the infinite-dimensional Hilbert space. The space of classical statistical states consists of Gaussian measures on $Omega$ having zero mean value and negligibly small dispersion. On one hand, the creation of such a prequantum model strongly supports attempts (first of all by Schrödinger and Einstein) to create purely field model of QM. On the other hand, it gives the possibility to go beyond QM. The main experimental prediction is that averages calculated in the mathematical formalism of QM (von Neumann’s trace formula) are only approximative averages. If predictions of PCSFT are correct then it would be possible to find deviations of experimental averages from quantum ones. | | Source: | arXiv, cond-mat/0506077 | | Services: | Forum | Review | PDF | Favorites | |
