Abstract

In this paper, a method is developed to investigate the relativistic quantum information of anyons. Anyons are particles with intermediate statistics ranging between Bose-Einstein and Fermi-Dirac statistics, with a parameter α\alpha (0<α<10<\alpha<1) characteristic of this intermediate statistics. A density matrix is also introduced as a combination of the density matrices of bosons and fermions with a continuous parameter, α\alpha, that represents the behavior of anyons. This density matrix reduces to bosonic and fermionic density matrices in the limits α0\alpha\rightarrow 0 and α1\alpha\rightarrow 1,respectively. We compute entanglement entropy, negativity, and coherency for anyons in non-inertial frames as a function of α\alpha. We also computed quantum fisher information for these particles. Semions, which are particles with α=0.5\alpha = 0.5, were found to have minimum quantum fisher information with respect to α\alpha than those with other values of fractional parameter.
