The probes are initially causally disconnected and non-entangled. We explore the parameter space $\\{{\\omega}, d_0, \\boldsymbol{v}_0\\}$ spanned by the energy gap $\\omega$ of the detectors, and the initial values of separation distance $d_0$ and relative velocity $\\boldsymbol{v}_0$, both covariantly defined in arbitrary curved spacetime.
