Population bound effects on bosonic correlations in noninertial frames
Abstract
We analyze the effect of bounding the occupation number of bosonic field modes on the correlations among all the different spatialtemporal regions in a setting in which we have a space time with a horizon along with an inertial observer. We show that the entanglement between A (inertial observer) and R (uniformly accelerated observer) depends on the bound N, contrary to the fermionic case. Whether or not decoherence increases with N depends on the value of the acceleration a. Concerning the bipartition ARbar (Alice with an observer in Rindler's region IV), we show that no entanglement is created whatever the value of N and a. Furthermore, AR entanglement is very quickly lost for finite N and for N{yields}{infinity}. We will study in detail the mutual information conservation law found for bosons and fermions. By means of the boundary effects associated to N finiteness, we will show that for bosons this law stems from classical correlations while for fermions it has a quantum origin. Finally, we will present the strong N dependence of the entanglement in RRbar bipartition and compare the fermionic cases with their finite N bosonic analogs. We will also show the antiintuitive dependence of this entanglement on statisticsmore »
