从信息处理原理推导狄拉克方程

Derivation of the Dirac Equation from Principles of Information Processing

G. M. D'Ariano, P. Perinotti

摘要:

我们展示了三维空间中的狄拉克方程是如何在不使用相对性原理的情况下,从满足么正性、局域性、均匀性和离散各向同性的最小非平凡量子元胞自动机的大尺度动力学中产生的。狄拉克方程恢复为小波矢量和惯性质量,而洛伦兹协方差是扭曲的超相对论极限。因此,自动机可以被看作是从普朗克到费米统一尺度的理论。一个简单的渐近方法导致色散薛定谔方程描述窄带状态在所有尺度上的演变。

英文摘要:

We show how the Dirac equation in three space-dimensions emerges from the large-scale dynamics of the minimal nontrivial quantum cellular automaton satisfying unitariety, locality, homogeneity, and discrete isotropy, without using the relativity principle. The Dirac equation is recovered for small wave-vector and inertial mass, whereas Lorentz covariance is distorted in the ultra-relativistic limit. The automaton can thus be regarded as a theory unifying scales from Planck to Fermi. A simple asymptotic approach leads to a dispersive Schroedinger equation describing the evolution of narrow-band states at all scales.
