On the possibility of decoherence due to a relativistic effect

Abstract

This note looks at the possibility of a system of free particles presenting decoherence in the total momentum when tracing upon their relative momenta if we take into account a relativistic correction to the expression of the kinetic energy.

Decoherence of macroscopic objects from relativistic effect

“…In this paper, we focus on its intrinsic origin which results in the minimum decoherence even in the absence of any usual environments. It has been found that the collective mode of MOs can be coupled with its inner motion modes [17,18]. C. Carazza has studied the decoherence effect of the collective variable for free quasi-relativistic particles [18].…”

“…It has been found that the collective mode of MOs can be coupled with its inner motion modes. [17][18][19] Carazza has studied the decoherence effect of the collective variable for free quasi-relativistic particles. [19] Nevertheless, for macroscopic objects, a more reasonable scenario should take the interaction between particles into account, since it is the coupling between particles that bound them into a macroscopic object.…”

Recently, Igor Pikovski et al has also studied decoherence due to gravitational time dilation in 2015.…”
