Abstract
We investigate the effect of qubit motion in terms of speed and acceleration on the variation in dynamic behavior of Wehrl entropy, second order correlation function and qubit–field entanglement. We consider three different coherent states of low-power potential (CSLPP) through the value of its exponent, specifically, the infinite-square, triangular, and harmonic potential wells. The relationship between the photon statistics quantified by the second order correlation function and nonclassical correlation of the qubit–field system is explored as the system evolves. The results show that the proposed scheme is very sensitive to the value of the exponent for both a moving and a stationary qubit. A high correlation between the qubit and CSLPP field is achieved by a proper choice of exponent, qubit speed, and acceleration.
