Space-time Interaction Principle as a Description of Quantum Dynamics of Particle

摘要: Abstract We propose a space-time interaction principle (StIP) which states any particle with mass m will involve random motion without friction, due to impacts from space-time. Every impact changes the amount \hbar for an action of particle. According principle, firstly, we prove coefficient must be \Re=\frac{\hbar}{2m_{ST}} deriving Langevin's equation corresponding Fokker-Planck Hamiltonian, where m_{ST} is sensible can derive that Schr\ddot{o} dinger equation, and reduce inertial in non-relativistic quantum mechanics. Secondly, show there exist smallest \bar{m}_{ST} as minimum mass, provided speed light vacuum maximum postulation special relativity. Furthermore, estimate magnitude this microwave background radiation. Thirdly, interpretation Heisenberg's uncertainty suggested, stochastic origin Feynman's path integral formalism. It shown construct physical picture distinct Copenhagen interpretation, reinvestigate nature reveal behaviours materialistic point view.
