Abstract:We study how the decoherence of macroscopic objects is induced intrisinically by relativistic effect. With the degree of freedom of center of mass (CM) characterizing the collective quantum state of a macroscopic object (MO), it is found that a MO consisting of N particles can decohere with time scale no more than √ N −1 . Here, the special relativity can induce the coupling of the collective motion mode and the relative motion modes in an order of 1/c 2 , which intrinsically results in the above minimum decoh… Show more
