 note = {Cu^+ ion behavior is one of the heavily discussed topics in physical and material fields because of its unclear behavior and high potential in materials application. To provide a breakthrough in this field, comprehensive research that connects the real space and the reciprocal lattice (momentum) space is effective. Here, we investigated the Cu^+ ion behavior in two-dimensional layered system Cu0.33TiSe2, which shows the Cu^+ disorder-order phase transition at 200 K. Inelastic x-ray scattering revealed a large change of the Cu^+ ion dynamics at the phase transition. It is expected that the complex interactions are involved in the behavior of Cu^+ ions intercalated in the negatively charged TiSe2 layers by charge transfer. However, Monte Carlo simulations using a simple combination of repulsive forces between Cu^+ ions well reproduce the characteristic temperature dependence of the anisotropic diffuse scattering. These insights provide a unified understanding in controlling the intercalated system.},
