• Abstract: In this work we consider basic characteristics of a quantum-classical continuous phase transition with spontaneous (non-dynamical) unitary symmetry (superposition) breaking (effective hiding). We clearly demonstrate that collapse (transition from superposition in corresponding statistical mixture of quantum states of measured quantum system by measurement or detection realized by appropriate measuring apparatus) represents in fact mentioned phase transition. Practically, collapse as an effective (non-absolute) phenomena can be considered as an especial case of the general formalism of spontaneous symmetry breaking (with applications in many different domains of the physics, e.g. in elasticity of rigid bodies, quantum theory of ferromagnetism, quantum theory of electro-weak interactions as well as in chaotic inflation cosmology), All this admits simple solution of the quantum mechanics foundation problem. Quantum mechanics (without any super-luminal dynamical effects) represents a natural bridge between classical mechanics and quantum field theory.

  This text begins with a series of critical considerations on the initial interpretation of quantum phenomena observed in atomic systems. Arguments are given in favour of the random zero-point radiation field (ZPF) as the element needed to complete the quantum process. The permanent presence of the field drastically affects the dynamics of the particle, which eventually falls under the control of the field.
